Square Wave Home UPS 800/1400 VA

  • Micro controller based design.
  • Quasi Square Wave output with close loop output voltage regulation, output voltages settable through preset.
  • SCR based phase angle controlled constant current charging, charging can be set between 1 Amps. to 15 Amps. through on board preset.
  • SCR short protection feature, in case SCR get shorted than this feature will save transformer from burning up.
  • Soft start for output voltages ensures smooth start of heavy load.
