VLA400-204 Powerex, Inc., 200 E. Hillis Street, Youngwood, Pennsylvania 15697-1800 (724) 925-7272 High Voltage Input DC/DC Converter Description: VLA400-204 is a non-isolated type DC-DC converter. Wide range of input voltage (DC 113V - 380V) enables direct connection to rectified 120V and 240V AC. This device is best suited for use as a pre-regulator for standard DC-DC converters.
