EPS Electric Inverter For Elevator / Industrial Three Phase Inverter

 

Energy saving, environment friendly,new generation EF series 3phase  EPS (Emergency power supply) 10-30kva

EF series 3phase emergency power supply adopted world leading online technology and network communication,small size, high efficiency, low noise ,low operation cost. Super sttong overload ability and rugged enough for any kinds of load, especially for elevator and industry useWith comprehensive protection, it’s widely used for elevator, factory, fire-fighting etc. 6KVA-30KVA.

 

Working theory:

This EPS is a power supply system with multiple protection and output isolated transformer.When AC is normal, it will provide output directly from the AC input and recharge the battery.When AC mains off or abnormal, battery power will converted to AC power  as output.

 

Working diagram as below:           

                                        

(1)When is AC normal, battery is under charging  and the output power is provided by the AC input.

 

(2)AC off or abnormal, battery supply the power to load via inverter

  

(3)input and output display

 

(4)DC voltage and temperature
