ES3 30KVA Single Phase UPS Power Supply

ES3 30KVA Single Phase UPS Power Supply
  • Model NoES3-30KVA UPS
  • Size
  • Operating temperature


This UPS system with pure sine wave output.
It can provide reliable and high quality AC power supply to a wide scope of applications from computer equipment, 
telecommunication systems to industrial facilities.
It outputs pure sine wave on inverter mode; 
when normal AC source is cut, 
it will turn into inverter mode automatically and provide back-up power from the battery.  


• Sine wave output applies to different kinds of electronic products as below.  
 Microprocessor control technique with high performance.  
Wide adjustable range for input voltage, high degree of accuracy for output, automatic voltage regulation.  
High reliability with protections for overload, short circuit, over voltage, under voltage and overheating.  
Modularized circuit PCB design for easy installation and field-maintenance.  
Instant auto-sensing and auto-adjustable chargers for optimized battery performance and prolonged battery longevity.  
Efficient toroidal transformer at lowest energy loss
