Autonomous Power Supply for Electric Hand Tools

         
   

 Technical characteristics:

  • input voltage - from 45 to 80 V;
  • output voltage (rectangular wave form with fill factor 0.8) - 220 V+ 10%;
  • output frequency is 50 ± 0.5 Hz;
  • output power:
    when working on electrical hand tools - to 2100 W.
    when working on the floodlight - to 1000 W;
  • efficiensy - not less than 0.75;
  • mode of operation: at polishing machine - intermittent, when working on the floodlight - long, up to 8 hours of continuous operation.
 
         
 

The device provides soft start mode, which increases the lifetime of both the voltage Converter and load. The circuit is protected with a utility model certificate (Russian Federation).
