Wiring

Three-phase five-wire system

Power distribution function

Multiple output power distribution function

Parameter display function

The voltage stabilizer screen has the functions of displaying operating parameters: three-phase voltage, three-phase current, and displaying fault information and fault records.

circuit control

Adopt digital (CPU) true RMS sampling control system

Automatic transfer to mains/bypass function

When a fault occurs, it can be automatically switched to the mains/bypass power supply without causing shutdown. To ensure that the power supply will not be stopped due to machine failure (self-recovery)

Protective function

It has overvoltage, undervoltage, short circuit, overcurrent, reverse phase, lack of equal protection functions. When the voltage stabilizer fails, the display screen can emit sound and light digital flashing alarm, and press any button on the display surface to mute the sound; other requirements ( 1) Communication interface: With RS232/485, it can realize remote control, remote signaling, telemetry, and monitor the working status and parameters of the voltage stabilizer in real time. All data must be set through the display panel, and the communication interface protocol is provided free of charge.

Overvoltage protection

246V±4%

Lightning protection function

The input is equipped with high performance or imported lightning protection system
