Series Description
The MGRI-20-R series features a range of high density board mounted isolated dc/dc converters. With a 12:1 ultra-wide input voltage range and reinforced isolation (4252 Vdc test) the MGRI-20-R delivers a double 10 W output channel. Available in 2x5, 2x12, or 2x15 volts outputs, each model features a trim function to adjust the output voltages in a 80-110% range.
The converter embeds several functions as soft start, over temperatures and output overload protection. The converter comes in a low profile fully potted metallic case.
