Electronics Type AVR-NU
Product Introduction
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. |

Output voltmeter indication |
|
|
This series AVR can maintain ≦5% voltage stability when the input is within-23% and + 30% range |
|
This series AVR has analog voltmeter giving clear indication of output voltage | |
![]() |
True RMS detecting circuit |
![]() |
Lightning surge protecting device |
|
|
It has precise True RMS detection and is capable to maintain accurate voltage regulation when the external power supply is distorted |
|
It has surge protection device and can effectively absorb 4500 A (8/20μs) and can effectively reduced the damage of thunder strike |
|
![]() |
Zero-cross transfer circuit, with longer life |
![]() |
Multiple Indication LED |
|
|
his series AVR owns accurate zero-cross circuit, the output is without power cut-off time while AVR is working |
|
Green LED light on at normal status, and red LED light on at input low voltage or overheat (same LED) |
|
![]() |
Automatic start delay with good protecting effects |
![]() |
Industrial class output socket, safe and reliable |
|
|
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 |
|
Output outlets of this AVR is with industrial class outlets, solid and durable and will not melt due to overheat as ordinary injection molding products | |
![]() |
Overload and overheat dual protection |
![]() |
Dual panel design with high reliability |
|
|
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 |
|
This AVR is in dual-panel design, precisely welded. High resistance to vibration, it gives higher reliability and longer service life |
|
![]() |
Full low frequency working, no interference to your equipment |
![]() |
High efficiency, high power factor, energy conservation and environment friendly |
|
The AVR is free of any high frequency transforming power circuit and won’t cause any high frequency disturbance | The AVR has efficiency at least 97%, and power factor is better than 0.98. it is the best green energy conservation product. |

High power factor, compact, safe and elegant |
![]() |
Over low/ high input voltage protection |
|
|
This series AVR is made of steel shell, it is good in fire protection.Compact, streamlined appearance, it occupy virtually no space |
|
When input voltage is too low, it will cut off output. When input inserted to wrong socket (such as 110V AVR inserted into 220V socket) and the voltage is too high, it will turn off internal and output power and will not damage your equipment as a result of over voltage |
