UPS Invertors

 

 

Square Wave Inverters
Salient Features :

 

  • Micro Controller Based Digital Inverter

  • Latest PWM Technology (Mosfet Based)

  • Intelligent Load Management (Auto Restart)

  • High Efficiency (Means Longer Back-up Time)

  • Pulse (SMPS) Charger ( Quick Charge even at low voltages)

  • Overload & low Batt. Cut-off with Audio-Visual Indication

  • Change Over Audio Indication

 

 

Sine Wave Inverter
Salient Features :

 

  • Highly reliable Digital Signal Processor (DSP) based design

  • Pure Sinewave Output (Low distortion, saves 38% on motor loads, 10% on fan loads)

  • Pulse (SMPS) Charger (Quick Charge even at low input voltages of 120 VAC)

  • Highly Fault-tolerant system, Protections for overload/ Short Circuit, battery cut-off, Output Wrongly Connected to Phase, Audible alarms for mains to inverter changeover and vice versa.

 

 

Mode of Operation

 

The Micro Controls Inverter/UPS works on Lead Acid Batteries. Whenever Mains fails, the inverter/ups changes over to the inverter/UPS mode instantaneously, and starts operating on the Batteries and supplies AC voltage to the connected loads. As soon as the mains power is restored, the Inverter/UPS changes over back to the normal mains power, and now starts charging the drained batteries for the next impending power failure.
