Complex computer centres, automatedproduction 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 behandled 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. ThePiller Static UPS meets the highestrequirements of a secure power supply and at the same time is veryeconomical.A combination of microcontrollers and the latest power electronic components control, regulate and...

For the same nominal power the AP Premium provides moreactive power (12.5%) than conventional UPS systems. This allows more loads to be connected. > Modern server power supplies tend to absorb capacitive currents. The AP Premium makes more capacitive power available than conventional UPS systems. 5 >

Conventional UPS systems absorb current which has very high levels of distortion(up to 35%). This distorted current causes an appreciable rise in the specified, limited harmonic level. In addition, such currents also have serious notches, which cause so-called commutation notches in the supply system. The result is a phase shift between voltage and current and thus reactive power absorption. Other UPS manufacturers install filter systems in the energy supply, resulting in over dimensioning of standby generating plant, cables and fuses. AP Premium eliminates this as it takes up sinusoidal current....
