True Online UPS Systems

MOSFET / IGBT BASED PWM TECHNOLOGY True on-line operation Double conversion with GALVANIC ISOLATION High frequency PWM IGBT/ MOSFET technology ensure lower switching losses Support critical load even under chronic brown  out condition without discharging battery Digitally processed sine wave Pulse With Modulation (PWM) technique helps to generate sine wave forms of very less harmonic distortion. Unique wave form correction circuitries ensures perfect sine wave even with non linear loads. Low acoustic noise  Soft start  Fast transient response High efficiency & Low harmonic distortion Easy installation & service spares easily available. User friendly front panel.
