FREQUENCY CHANGER

50-60 Hz to 400Hz, 3 Phase

SPC6 1000The SPC-6-1000-3PH solid state frequency changer converts 115 VAC 50/60 Hz to 115/200 VAC and 26/45 VAC, 400 Hz 3Ø sine wave power. The SPC-6-1000-3PH is designed for use on test benches to check radars, compasses, gyros, synchros or any instrument requiring 3 phase power.

The SPC-6-1000-3PH-230 and SPC-6-1000-3PHC are frequency changer models available for 230 VAC 50 Hz operation.
