UNIQUE FEATURES
The Phase Selector:
- Micro controller based. Hence all parameters like change over times etc., are better tuned and optimized.
- Senses Phase to Phase voltage, hence works well even if there is a problem with neutral line. And does not get confused with reverse voltage that comes back from the power transformer.
Static Voltage Regulator:
- Wide input voltage range, 3 tap model works from 150 - 280 Volts and 4 tap model from 135 - 280 Volts.
- Micro controller based. Proper tap change points, proper hysteresis, proper protection against possibility of thyristor failures. Proper visual indication in case of thyristor failure.
- Bypass Switch: In case of SVR failure, bypass switch acts redundent, reduces down time in case of any failure in SVR (optional)
