URB_LD-30WR3 series are isolated 30W DC-DC products with 4:1 input voltage. They feature efficiency up to 90%, 1500VDC isolation,
operating temperature of -40
℃
~+75
℃
, Input under-voltage protection, output short circuit protection, over-voltage protection,
over-current protection and EMI meets CISPR22/EN55022 CLASS A, which make them widely applied in data transmission device, battery
power supply device, tele-comunication device, distributed power supply system, remote control system, industrial robot fields. And
extension package A2S and A4S also enable them with reverse voltage protection.

Notes:①Series with suffix “H” are heat sink mounting; series with suffix “A2S” are chassis mounting,with suffix “A4S” are DIN-Rail mounting, for example
URB2405LD-30WHR3A2S is chassis mounting of with heat sink,URB2405LD-30WR3A4S is DIN-Rail mounting of without heat sink; If the application has a
higher requirement for heat dissipation, you can choose modules with heat sink;
②Absolute
maximum rating without damage on the converter, but it isn't recommended;
③Efficiency
is measured In nominal input voltage and rated output load;A2S (wiring) and A4S (rail) Model due to input reverse polarity protection,
minimum efficiency greater than Min.-2 is qualified.
