Features of the Shiva Amvaj Phase Controller
Accurate mains monitoring because neutral is not used (neutral sometimes becomes live)
Protection against
Over-voltage and under-voltage
Phase sequence error (swapping) and phase asymmetry
Loss of any phase
4 indicators to signal
AC: Mains power
REL: Relay on
F: Over-voltage, under-voltage and phase asymmetry
P: Phase sequence error (swapping)
Adjustment screws for setting asymmetry and turn-on time
Parameters do not change due to panel contactor shocks
