the se25 is primarily designed to power 115 vac line to neutral or line to line 400 hz three phase wye or delta system loads with maximum continuous output power of 250 va. Se25 inverter applications include airborne or ground instruments, navigation equipment and radar systems. the se25 operates from a 28 vdc source and the output can be configured for three wire 115 volt delta load, or four wire 115/200 volt wye loads. Each ac output phase (? A, ? B & ? C) is isolated from the dc input and chassis ground. The se25 is interchangeable dimensionally with 250 va inverters conforming to ms21983-3.
