Rotabloc Rotary UPS

Rotabloc is an Electrically Coupled Rotary UPS System made in the U.S. and Europe

Designed to Protect Against Electrical Disturbances in the Event of Power Failures as well as Applications in Need of Improved Power Quality

IEM Power Systems has developed the complete UPS system to protect Critical / ‘No-Break Loads’ against electrical disturbances in the event of power failures, voltage transients, or slow voltage fluctuations.

Our simple, robust design allows for low maintenance while guarantees maximum reliability.

Rotabloc is electrically connected to the back-up generator, providing advantages including:

  • Locating the engine genset remotely – saving valuable internal space
  • No mechanical wear when the generator is engaged – increasing reliability and reducing maintenance
  • Safely test or maintain the energy storage unit and the engine generator separately
  • Ability to utilize a site’s existing engine generator assets

Rotabloc UPS also employs an electro-magnetic coupling to harvest the stored energy without friction or wear during sustained Utility failures. This patented energy transfer system reduces maintenance and further increases reliability.

No other UPS provides the same simplicity, reliability and efficiency delivered by the Rotabloc system.

The result is a RUPS with the most favorable TCO for your project.

IEM Power Systems is the only UPS manufacturer that will build, integrate and test your system in the factory as standard.
