Caterpillar, Holt and Active Power Demo CAT UPS

December 13, 2001 by Jeff Shepard

Caterpillar Inc. (Peoria, IL), Holt Power Systems Inc. (Sacramento, CA) and Active Power Inc. (Austin, TX) held a power quality seminar and demonstration to unveil the CAT UPS battery-free, energy solution on December 14, 2001, in Sacramento, CA.

The presentation included simulated power outages in which the CAT UPS flywheel system provided ride-through utility power until the Caterpillar generator started. The CAT UPS

system is integrated with a flywheel motor-generator, CleanSource, which stores kinetic

energy. The stored energy is instantly converted to electricity and powers the critical load during utility disturbances or until a standby generator takes over. The power-dense system, jointly developed by Caterpillar and Active Power, provides

back-up power in a compact, efficient, low-maintenance package.
