Static UPS from 3kVA –500kVA

Complex computer centres, automated production plants and other critical applications make high demands on UPS systems, as power supply failures can have catastrophic results. Non-linear loads therefore have to be handled as safely as shock loads and overloads such as those caused by power surges. When it comes to the security and economy of a UPS system, there is no room for compromise. The Piller Static UPS meets the highest requirements of a secure power supply and at the same time is very economical.

3kVA up to 10kVA


10kVA up to 80kVA


100kVA up to 500kVA

Why Piller's Static UPS?

A combination of microcontrollers and the latest power electronic components control, regulate and monitor the UPS functions to ensure maximum reliability. The Piller Static UPS is a true online UPS with VFI SS 1111 characteristic double voltage conversion and continuously supplies a constant voltage and frequency. Even in the event of a mains failure, the load is supplied by the inverter without interruption. 

At the same time and even with a 100% unbalanced load, Piller Static UPS maintains accuracy at the high output voltage to avoid jeopardising the operation of the critical loads. Varying loads do not affect the quality of the output voltage. They are corrected by the inverter by means of pulse width modulation with instantaneous value accuracy and variable pulse frequency.

Non-linear loads, the predominant part of all systems, generate high peak currents – the quality of the output voltage is maintained even with a 3 times peak current crest factor with respect to the rate current (distortion factor up to 3%).
