Pure Sine Wave Inverter

General Details

Inverters, as the name suggest inverts DC current to AC current. DC power is fed as input from battery banks to this inverters. full bridge topology using IGBT / Mosfets driven and controlled by DSP based microcontroller is used to convert this DC power to AC power along with other features for safe operation and better control. This AC power generated is a 50Hz pure sine wave as that of utility supply. Inverters are fully protected against output short circuits and overload conditions.

Product Highlights

  • Pure sine wave output to run all appliances.
  • Input and output fully isolated design.
  • High efficiency up to 94%.
  • Capable of driving highly reactive and capacitive loads at start moment.
  • Digital signal controller based technology using MOSFET’s.
  • Soft start capability for starting heavy loads.
  • Protection like low input voltage, overload, short circuit, low battery indication, input – over voltage and over temperature.
  • On-load switch/circuit breaker.
  • Circuits like pilot generator, power stage regulator, gating pulse generator, input filter control, alarm and supervisory circuits.
