Static UPS 3kVA to 400kVA

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.

 Suitably designed UPS systems are a permanent part of the building structure and involve a high level of investment therefore there is no room for compromise when it comes to the security and economy of your UPS.  The Piller Static UPS product range meets the highest requirements of a secure power supply and at the same time is very economical.

 A combination of 16-bit microcontrollers and the latest power electronic components controls, regulates, monitors and ensures all UPS functions perform with maximum reliability.
