Powervar UPS range provides reliable power

It has power-factor correction circuitry that raises the input power factor to near unity (more than 0.95).

The input current is in phase with the input voltage and harmonic distortion of the input current (THDi) is kept to less than five per cent.

This ensures that the UPS does not add to the power-quality problems of the facility or create interference for other electronic devices powered from it; and that the facility is not affected by the non-linear load connected to the UPS, which means that the UPS prevents its connected loads from contributing to heating of conductors or the tripping of magnetic or leakage-type circuit breakers.

Power-factor correction stabilises the battery buss voltage, so battery lifetime is improved, and the UPS may be paired with generator set without the need for oversizing of the generator.
