Flywheel Uninterruptible Power Supply
Power Systems & Controls’ Series NB is a “battery-less” Flywheel Rotary Uninterruptible Power Supply (RUPS) system designed to provide the same proven power protection as our battery supported Rotary UPS systems (Series MC and Series XC) without the need and cost associated with battery modules. The core of the Series NB is the flywheel extended power module. The flywheel converts rotational energy into mechanical energy, which is then stored to bridge the power gap should normal utility power fail. The PS&C flywheel rotary uninterruptible power supply was developed to start the back-up engine generator and seamlessly provide continuous electrical power to the critical load. The Flywheel Rotary UPS comes in single modules, as well as, paralleled systems for complete N+X redundancy.

- Lower Insurance Premiums
- Integrated Quiet Design
- High Speed Digital Controls
- Versitile Communications Platform
The Series NB helps to guarantee the lowest possible power bill and the highest electrical power quality. It has been designed to protect demanding electrical systems like variable speed motor drives, which other power conditioning technologies simply cannot handle. Sizes are available from 25 to 2500kVA. If your backup requirement is longer than typically requested, Power Systems & Controls can parallel flywheel modules together to achieve the desired time. However, the quantity will have an impact on the UPS system’s overall weight, dimensions, and cost.
The electrical isolation of the rotary UPS is not derived from the flywheel, but rather the motor generator that is incorporated into the primary power path. The electrical isolation is only possible because the motor and generator are distinctly separate with their own carefully grounded frames, which are tied together mechanically through precise coupling. This mechanical separation is the only way to electrically separate utility from the load.
Power Systems & Controls’ Flywheel Rotary Uninterruptible Power Supplies are setting the industry standard for what a customer has grown to expect from a flywheel system as it comes with a color touch screen display to illustrate all important functions and overall information. There are also numerous options for the “battery-less” UPS ranging from advanced remote communications/controls to customized NEMA enclosures and ISO containers for special applications.
