Three Phase Voltage Stabilizers
Features
- Fully Solid State Circuit for highest reliability.
- Auto/Manual facility-- in case of control card failure manual control of output is possible from front panel. (Provided only in units above 5 KVA 1Ph.)
- Unaffected by Load Power Factor.
- Zero waveform distortion & phase shift introduced in stabilizer.
- Output Cut-Off by means of relays/contactors in each unit.
- Input Short Circuit Protection by means of fuse.
- Output Short Circuit Protection by circuit of MCB.
- Audio & Visual Indicators for over/under voltage cut-off.
- Easy servicability through plug in type PCB.
- Built-in Analog meter to Monitor Input & Output voltages by means of Selector switch
