Wilmore Electronics announced that its low-profile, 1000-VA dc-to-ac inverters are now available with an optional built-in automatic load switchover feature that lets them operate in uninterruptible power supply or stand-by modes. The devices fit in 19- or 23-inch racks and are available in 24-, 48- and 130-Vdc input versions. They are designed for use in telecommunications, SCADA and security applications where a stable and reliable source of ac power needs to be derived from a dc-power (battery) system, the company said.
