Description :

Specially for automatic control and distribution panel
Compact size NU series electronic Automatic Voltage Regulator is in all-electronic automatic control. It is featured with rapid voltage regulation, frequency wave of output is same as input, free of distortion and has very wide input range. It can absorb surge instantly and there is perfect protecting devices that is suitable for area with instable voltage or where steady voltage required.

Features :

* Very wide input voltage range- This series AVR can maintain ≦5% voltage stability when the input is within-23% and + 30% range
* True RMS detecting circuit- It has precise True RMS detection and is capable to maintain accurate voltage regulation when the external power supply is distorted
* Zero-cross transfer circuit, with longer life- This series AVR owns accurate zero-cross circuit, the output is without power cut-off time while AVR is working
* Automatic start delay with good protecting effects- The AVR will delay the start 4 seconds automatically when physically started and when mains is resumed after black out, it can protect your equipment from damage of transient high voltage of surge
* Overload and overheat dual protection- The AVR has overheat protection, in addition to the overload protection, when transformer temperature is too high, it will cut-off output of AVR automatically
* Full low frequency working, no interference to your equipment- The AVR is free of any high frequency transforming power circuit and won’t cause any high frequency disturbance
* Output voltmeter indication- This series AVR has analog voltmeter giving clear indication of output voltage
