First of all – for stable power supply of electronic devices, computer equipment, as well as any equipment with the electronic power supply unit. It was specifically designed for safe operation of the load.
Inverter voltage regulator with advanced protection without energy accumulation.
Extinguishes dangerous voltage spikes before they hit the load.
There are two types of double energy conversion regulators – with the accumulation in internal tanks and with the return of energy to the grid.
– when the input voltage is extremely low or extremely high;
– when there is a manufacturing plant in the neighborhood and its equipment gives dangerous emissions when disconnecting or operating machines, engines, welding machines or frequent and sudden voltage spikes in your grid.
– when you yourself are the production, to stop the grid from sagging when the motor starts (limit the maximum output current in the load);
– when it is necessary to improve the shape of the voltage to reduce the heating of various motors or the humming of transformers at the consumer;
– when it is necessary to return electricity to the grid, for example – if you have a solar power plant;
– when there is especially little space for installation, but a powerful regulator is required
– to compensate for reactive power, if the permissible limit of reactive power consumption in the office is exceeded (for example, many fluorescent lamps with ballasts)
– when it is necessary to provide stabilization of large production, as Quant is able to work in a group in parallel, allowing to make three-phase clusters up to 0.5 MW of capacity and more;
– when it is necessary to achieve 100% consumer protection;
The output voltage will always be stable and equal without overvoltages, especially short-term, which are dangerous for electronics and can cause its failure, remaining “uncaught” for thyristor / triac / relay / servo-motor regulators, no matter what happens on the input.
There is no problem with loss of power when the grid voltage is too high. The regulator will always deliver its maximum rated power.
Since it is a household regulator, its power is not reduced, but the power that the grid can give it to transmit to the load can be reduced. If the input circuit breaker is rated at 40A, it can deliver 8800 watts of power at 220V. If the grid sags to 110V – it can give only 4400 watts of power, as a voltage-to-current conversion. According to the contract with the energy supplier you will not be able to take more than 40A of current from such grid.
The principle is that if something really dangerous suddenly appears on the input, it is firsty limited to a level that is safe for the regulator itself (in practice these are pulses not higher than 600V or AC voltage with an effective value lower than 380), then the regulator brings these values to nominal, as its principle of operation allows it to “catch up” with as many rapid surges in voltage as it’s possible, so that they do not exceed dangerous values for it.
Only when the regulator has failed. No need to use Transit mode without an absolute necessity. And yet, if you use the mode – turn off the delicate electronics from the grid, most likely you only need the lights at such times. Remember – the regulator does not turn off the input circuit breaker for no reason. Most likely, if disconnected – there is an emergency in the grid. Same mean if it failured. In an emergency (neutral wire disruption, phase to ground fault in an overhead line or line failure in a multi-story building), the Transit mode does not provide sufficient protection.
Yes, it works, but in this mode it does not bring the level of power pulses to the nominal value, but only to 530V – 550V. Safety of electronics, which corresponds to the so-called ITIC (CBEMA) curve will provide with a high probability, but most electronics, unfortunately, meet these curves in full, real safety can only be obtained by continuously maintaining the nominal voltage of 220-230V, even without short overloads, even for a few microseconds.
Yes, it can withstand short-term overloads of up to 25% of nominal for 10 seconds. Withstands also short circuits on the output, while giving the maximum current (up to 200% of nominal) for up to 0.5 sec.
When the permissible overload is exceeded – the input circuit breaker is switched off.
When there is a short circuit on the output – it shuts down the output, considering it as the connection of a powerful load with a large starting current. But before that, repeat the attempt to start 10 times at intervals of 6 seconds. This mode allows you to avoid ignition wiring due to short-circuit current heating, increases safety, but at the same time allows you to start the load, start power of which exceeds the power of the reguator (remember, that the output voltage at the start will drop sharply. This is not a regular, but an additional mode, it is better to buy a regulator with a reserve for start power, as traditionally it is always done).
Interesting to know
If a powerful machine, industrial fan, compressor or powerful pump is fed through the Quant regulator, it will allow the load to start softly at the moment of start when the current is maximal and the voltage is minimal (sagged by the load). Naturally, its output will “sag” for the start-up time, so you will need to either tolerate a short “sag” of the lights, or feed a heavy load with a separate regulator, and the lights – separately.
For production it is optimal to divide the necessary power into parts: one – for the lights, computers, other electronics, and another for machines, welding, other “interfering” consumers, also instead of one powerful stabilizer to put two less powerful.
Because during start-up the engine requires only a multiplied current, not the power. The regulator gives it an increased current, reducing the output voltage, after accelerating the rotor, the voltage increases to the nominal value and further – steadily and accurately maintained. Thus there is no excess of power on an input, and, accordingly, there is no excess of current consumption from the grid.
You can save money by paying for reactive power in the office or in the workplace. The household consumer does not pay for reactive energy at all. Its meter does not count it, so there will be no savings in the household. But with a severely overloaded grid at least your consumption from it will be 2-3A less as at least from your load at least reactive current will load a grid less.
For your interference-sensitive electronics to work properly. And also loading of strongly “sagged” grid decreases, the form of output voltage improves, harmonics are extinguished. Of course, the main part of the work to improve the form of the output voltage is the regulator itself.
Quant Voltage Regulator is a instantaneous regulator. It has no delay to regulate the output voltage. We can also say that it does not react to surges and spikes on the input – no matter what happens, the output does not apply, it always has a nominal voltage – 220 or 230V.
This is the work of several regulators on one line, on a common load, combining their outputs through a special device that needs to be agreed (separately paid, or as a bonus when buying several regulators, depending on the terms of purchase).
– when it is necessary to improve protection against dangerous high-voltage emissions in the workplace
– when it is necessary to increase the survivability of the system, in this case the power of regulators is set higher than the consuming load, then shutting off some of them does not affect the operation of the system.
– when it is necessary to gain any desired power, say, when production has grown you can buy a regulator of the desired model. This is more profitable than putting one powerful regulator, as the protection of the cluster of QUANT regulators increases when connected in parallel.
Regulators capacities sum up, load consumption is divided exactly by all the parallel regulators without losses.
In addition, if one of the regulators is turned off – the power is instantly distributed evenly over the rest, increasing the survivability of the system.
Of course it is! Maintenance of such a system is easier, the weight and dimensions of separate parts simplify logistics, and even without a power reserve the system remains working capacity at less power (or it is possible to hot-swap just one unit from the cluster, which also simplifies maintenance and does not leave the facility without power).
Quant regulator does not operate with a generator. Therefore, the installation of the Quant regulator must be installed before the diesel generator.
Note: diesel generators are different in quality. The “nominal” power may suddenly be actually less than expected according to the generator instructions. If the output of the generator “sags”, that is, its own voltage regulation fails, it means that it has exceeded its nominal power. The regulator in this case is useless, it will not pull more power, and will sag the output even more. There will be nowhere to get extra power. It is necessary to reduce the load on the generator or take a more powerful generator, guided by practice, not its advertising. Then again the regulator will not be needed, because the generator voltage is maintained at the nominal.
When a powerful generator feeds the entire production and part of the power consumes office equipment (computers, lighting, CCTV cameras, other sensible electronics), in this case this part of the consumers also cannot be fed through the regulator. Always consult our brand manager in advance.
It differs in the fact that it precisely limits the voltage, not allowing even short exceedances of the safe level. That guarantees the survival of the regulator and its loads in our grids, whether it is a Chinese mobile phone charger or expensive medical unique electronic equipment, computer or laptop.
There is nothing to hum or buzz at operating temperatures up to 65ºC. If the temperature is higher – the regulator turns on a fan for active cooling, but due to the high efficiency of the regulators, it does not work at maximum speed, but only helps the natural cooling.
Due to the use of new technologies and modern components it was possible to achieve a significant reduction in weight and dimensions in the entire model range.
Due to the double conversion of the input voltage. During the double conversion, all harmful effects on the input load are eliminated.
But the main thing is that due to the special absorber of dangerous pulses and overvoltages on the input of the regulator, any overvoltages at a level safe for the regulator itself is strictly limited, after which it is able to maintain the output voltage exactly at the nominal value. The unique property of the limiter/absorber is that it is designed with a reserve for the entire service life of the regulator, it does not limit the number of operations and does not contain wearing parts (cartridges) requiring replacement, as traditional “SPDs”.
The basic warranty is only 5 years. You can also get an additional warranty if you register the serial number of the regulator.
The service life or resource of the Quant regulator is not less than 12 years from the moment of the beginning of operation.
The service life of the Quant regulator is provided by a careful choice of branded accessories and carefully calculation of their operating modes at development. And also by the modular design that allows to repeatedly test individual modules in the course of the assembly, then the assembled product, and then – a test run on the stand. The assembler of each subsequent stage once again checks the work of the preliminary stage of assembly. The controller returns the product if the appliance does not operate as it should in accordance with the installation instructions (but this happens quite rarely).
The service center is located at 238 Zelena Street, Lviv, in the premises of the store “ElectroPatron”. If the product fails – the user receives a replacement.
Operation with solar power plants
Quant will operate with SPP, both on input and on output. That is, if the neighbors have an SPP on the line and it creates problems in the form of surges every time its inverter overvoltage protection is triggered is triggered (for example, when the sun is too bright), then these sharp voltage spikes can be eliminated only by an inverter regulator, such as Quant.
Otherwise, the connection of the SPP to the output of the regulator in order to “pump” the required amount of energy through a weak line to increase the voltage in it is acceptable only for the dedicated line. Otherwise, the equipment of the neighbors on this (common) line may fail (Quant can output up to 350V into the line when switched back on, if such a cutoff threshold is selected in the regulator settings).
Yes, it regulates, but the solar inverter, which is designed for own use, already has a stable output voltage that does not require additional regulation. If there is not enough solar energy and the voltage is less than normal, the regulator will not be able to help, because not enough energy is generated to maintain the necessary nominal voltage.
Yes. Thus it is better to connect the inverter properly – in a line, and the regulator will already be fed from the same line. If the voltage in the line is such that the inverter itself cannot be started, then the inverter can be connected to the output of the regulator, but the tripping threshold at the input in the regulator should be set to a safe level – 260-270 V, otherwise, those consumers who are fed from the same line, will receive dangerous voltage for their equipment.
Yes, there is almost nothing to replace Quant in case of problems with the neighbor’s SPP, because in excessive sunshine, when the SPP inverter overvoltage protection is triggered on the output, surges can be very sharp and large in amplitude. An ordinary regulator can even exacerbate the problem, but a household regulator such as a Quant can easily handle it and provide 220 (230V) output, without surges and fluctuations.
Yes, this may be the reason for such a connection, although the solar inverter usually has its own protection mechanism against emergencies and high voltage on the output.
