URB_YMD-20WR3 series of isolated DC-DC converter products feature an ultra-wide 4:1 input voltage with efficiency of up to 91%, 1500VDC
input to output isolation, an operating ambient temperature range of -40℃ to +105℃, input under-voltage protection, output
over-voltage, overcurrent, short circuit protection, which makes them widely used in industrial control, electric power, instruments and
communications applications. Optional packages are offered for chassis or DIN-rail mounting (A2S, A4S), adding additional input reverse
polarity protection.

Notes:
1
Use “H” suffix for heat sink mounting, “A2S” suffix for chassis mounting and “A4S” suffix for DIN-Rail mounting. We recommend to choose modules with a heat
sink for enhanced heat dissipation and applications with extreme temperature requirements;

The A2S and A4S Model’s start-up and minimum input voltages are increased by 1VDC due to the input reverse polarity protection circuit;
Absolute maximum stress rating without damage (not recommended);
Efficiency is measured at nominal input voltage and rated output load; efficiencies for A2S and A4S Model’s is decreased by 2% due to the input reverse
polarity protection circuit.
