3 phases + 4 wires + PE IPM module EPS Emergency Power Supply for centralized control
Our EPS YJS series is extensively applied to banks, hospitals,
hotels, markets, schools, bus or rail stations, sea or air ports,
exhibition buildings, sport buildings, tunnels, etc.
Our lighting power EPS adopts intelligent IPM module, which ensures
the output is reliable and balanced.
It can be used together with fireproof linkage system for
centralized control.. CPU control and pure sine wave output.
Inductance and mixed load devices.
RS232 or RS485 remote monitoring.
Designed with both LED and LCD display.
Easy maintenance, long service life, and energy saving.
