Voltage stabilizer thyristor NIK STV-12

Stabilizer thyristor booster type NIK STV-12
STV stabilizers are used to limit the impact of voltage fluctuations on the operation of electricity consumers and provide:

equipment operation in a wide power supply range from 145 V to 275 V;
undistorted sinusoidal output voltage and work in the entire range of output loads (from idle to maximum load);
short circuit protection:
— electronic protection against impulse current — 2 ms;
— high quality circuit breaker;
protection against pulsed input voltage — over 275 V, response time 8 ms;
protection against undervoltage — 145 V, response time 100 ms;
work in the «transit» mode in an emergency;
motor protection
For the convenience of viewing the measurement data, a LCD display is installed on the front panel. The device is installed to improve the quality of power supply of apartments, houses, offices, industrial enterprises.
