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. 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.

APOTRANS Static Transfer Switch

All around the globe complex electrical and electronic processes, information technology and automation, govern our manufacturing, service industries, data management and communications.

In today’s fast-moving world, Piller continues to develop new and innovative solutions to meet the challenge. As the requirement for resilient and redundant power supplies is growing, the Piller APOTRANS represents the latest evolution of redundancy. 

The APOTRANS static transfer switch is suitable either as a retrofit to existing power distribution systems or for new systems. It supports critical loads by invisibly switching to an alternative power source should the preferred source become out of tolerance or fail completely. From 25A to 63A to 125A to 1600A units, Piller provides the optimum solution.

Energy Storage Flywheels and Battery Systems

Piller offers a kinetic energy storage option which gives the designer the chance to save space and maximise power density per unit. With a POWERBRIDGE™, stored energy levels are certain and there is no environmental disposal issue to manage in the future. Importantly, a POWERBRIDGE™ will absorb energy at the same rate as it can dissipate. That means the POWERBRIDGE™ can stabilise a diesel engine and that frequency stability under dynamic load conditions cannot be matched by any other kinetic storage solution. A vertically mounted flywheel and generator utilising magnetic bearing technology, the POWERBRIDGE™ is available in a number of sizes for different power ratings and ride-through autonomy.
