China 600kVA 800kVA 1200kVA 2000kVA WB low voltage regulator

WBLVR Solve the Terminal Voltage Problem
8 gears of boosting voltage& set down voltage by using reversing relay;
It will output 5Vrms for each gear of switch, during switching, power supply will not be broke off and no sudden change;
By SCR zero-crossing switch and by pass relay, fast gear shift, low loss, long life, the output has no impact;
LVR can still normally work at the rated capacity while the input voltage is as lower as 150Vrms (output is 183Vrms );
Voltage regulating/ba pass can be switched manually;the bypass capacity is twice the rated value;
With output overload protection, transformer vertemperature protection, output short circuit protection(internal circuit breaker);
Equipped with temperature-controlled fan, LVR will cool itself naturally for saving energy when the ambient temperature is low, but LVR will be cooled automatically by a fan at high temperature;
The efficiency of voltage regulating of LVR is very high, and it will be by pass status while it does not work for saving energy;
With capacitance compensation(optional), auto zerocrossing switch according to loads change, and capacitor bank has over-current protection;
The minimum maintenance voltage is 90Vrms, it will not output if output is lower than the maintaining voltage;
With maintenance bypass(optional);
With internal transformer over-current protection, LVR can be protected in a safe status when malfunction such as short-circuit occurs in internal ;
Using DSP for intelligent control, protection and real-time fault diagnosis;
With the LCD, checking the fault record, set parameters, etc.
With WIFI module, it can be convenient maintenance and setting;
Extensible 485module,GPRS module;

LVR Working schematic diagram:
WBLVR devices is connected in series with the low-voltage lines at the user end, real-time detect input voltage Ui (the voltage before it is being raised) and the output voltage Uo. When the input voltage Ui is too low, the voltage compensation module will give another corresponding voltage to the load according to the actual input voltage so that the output voltage Uo can satisfy the normal operation of the load, thereby giving the qualified voltage of the power supply to the terminal user and solving the low-voltage problem.
