AUTOPRO UPS System a reliable Partner in the office electrical characteristics

HF series online UPS System from Professional Lighting Pvt. Ltd. are becoming more and more popular as an power conditioning equipment in large computing enviornments. AUTOPRO UPS Systems are built with latest technology that results in higher efficiency and minimum downtime.

Dual Conversion technology constantly converts incoming AC to filtered DC power before it is inverted back to frequency controlled AC power. The higher efficiency of AUTOPRO Inverter ensures that the losses are very low during operation. This dual technology is highly appreciated in large computer system setups.

Multiple SPWM Technology results in higher electrical efficiency. This reduces considerable power bills. Moreover the load on power lines in the establishment reduces thereby eliminating line drops, conductor heating etc.

Professional Lighting Pvt. Ltd. uses latest semiconductor components, and high quality magnetic transformers that results in low losses during power conversion. The efficiency of the whole system is improved.

As recommended by leading computer consultant, the output waveform of AUTOPRO UPS System is pure sinusoidal with less than 3% distortion even at full load.

All the UPS Systems are tropicalized for Indian line conditions.
Simple Straight forward and elegantly designed front panel layout makes the unit easy to operate and observe the status of the UPS System.
