AEG SVS Power Introduces the SVS 20kVA UPS

July 30, 2000 by Jeff Shepard

AEG SVS Power Supply Systems GmbH (Furth, Germany) presented their new UPS at the Hanover Trade Fair 2000. According to AEG SVS, this new UPS is the first to make exclusive use of UltraCaps from EPCOS AG as the storage medium instead of lead-acid accumulators.

The new UPS uses a total of 115 UltraCaps with a capacitance of 2,700 farads each connected in series and supplies an energy of 450kW. Presented in a UPS model SVS Protect 5.31, the altered model supplies a maximum of 20kVA and features a bridging time of 30 seconds under full load. According to AEG SVS, it can compensate more than 95 percent of all power failures. If outages of longer duration have to be managed, a diesel generator can be started during the bridging 30 seconds.

The new UPS is based on proven continuous conversion or online technology, meaning the line current is continuously rectified, buffered and inverted again before being supplied to the load. In addition to the no-delay switch-over to storage operation, the technology offers filtering of harmonics, spikes and other net-work glitches. The double-layer capacitors, such as UltraCaps, are designed to handle more than 500,000 charging/discharging cycles during a minimum operating life of 10 years, with no change in their capacitance as a function of time.

According to AEG SVS, the UltraCaps do not need regular maintenance cycles and test runs and can be completely discharged, if necessary. UltraCaps feature an approximate charging time of a few seconds. The UltraCaps' permissible temperature range is -30 degrees to 70 degrees C.
