Active Power has responded to growing market requirements for continuous power solutions by enhancing its popular CleanSource dc line of battery-free energy storage systems to include expanded power levels and incorporate several changes in the evolving product line. Based on Active Power’s proven flywheel technology, the new models provide tightly regulated, adjustable dc voltage to replace or augment batteries configured with uninterruptible power supply (UPS) systems backing up critical applications in the 100-kW to 2000-kW power ranges.
The new and enhanced models are available with unit power ratings of 100 kW, 140 kW, 200 kW, 250 kW, 425 kW and 500 kW, and can be paralleled in combinations up to 2000 kW. They accept an input float voltage from 400 Vdc to 600 Vdc to supply a charging current of 15 A to 100 A per flywheel. User-adjustable output voltage can be set from 360 Vdc to 550 Vdc with ±1% steady-state voltage regulation. Unlike batteries that must be maintained as close as possible to 20°C to avoid performance degradation, the CleanSource DC models are designed to operate comfortably from 0°C to 40°C.
