Electronics Type AVR-NU

NU Electronics Type Power Conditioner
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.

 

Feature:
         

Very wide input voltage range

 

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
