SALIENT FEATURES
BENIFITS

Balance output

Suitable for balanced 3 phase load. (no Need of unbalance 3 phase inverter which is more expensive)

IGBT based inverter

Rugged design, can deliver 5 times peak output current, suitable for lifts with A/c drive

IGBT based smps battery charger

a)Wide input voltage range
b) Low ripple dc charging current
c) Less heating of batteries so battery life improves

Automatic changeover

No attendant required
