Description: M57120L is a non-isolated DC-to-DC converter with a built-in transformer. Wide range of input voltage (DC 113V-400V) enables direct connection to rectified 120V and 240V AC. This device is best suited for use as a pre-regulator for standard DC-to-DC converters. Features: Wide Range of Input Source Voltage (113V-400V DC)
