Lighting Power Saver

Image

1. Introduction

At the trend of energy saving,ONEXT ELECTRIC have developed ZJD serie interlligent non-contact lighting power saver.
The product is controlled by MCU,According to lighting characters nowadays,it could meet lighting time requirements,it is programmable to output different voltage.

2. Working principle

Adopting microcomputer intelligent test,quick swith between IGBT or SCR,it is programmable according daylight to save electricty in the principle of sin. wave composition compensation.
It's characters are programmable,high setting accuracy,no carbon brush,non-contact,maintenance-free,3 phase auto balance.
128*64 LED screen could appear voltage,current,power,working state,it could output different voltage by programming.With RS232 inteference,sets of power saver could be monitored by remote computer.
