Feature

• 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
 

• Over low/ high input voltage protection

        When input voltage is too low, it will cut off output.
When input inserted to wrong outlet (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 high voltage
 

• 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
 

• Lightning surge protecting device

It has surge protection device and can effectively absorb 4500 A (8/20μs) and can effectively reduced the damage of thunder strike
 

• Multiple Indication LED

       Green LED light on at normal status, and red LED light on at input low voltage or overheat (same LED)
 

• Industrial class output outlet, safe and reliable

Output outlets of this AVR is with industrial class outlets, solid and durable and will not melt due to overheat as ordinary injection molding product
 

• Dual panel design with high reliability

     This AVR is in dual-panel design, precisely welded. High resistance to vibration, it gives higher reliability and longer service life
 

• High efficiency, high power factor, energy conservation and environment friendly

       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

        This series AVR is made of steel shell, it is good in fire protection.
Compact, streamlined appearance, it occupy virtually no space
