provide 10 Watt output power, with 4:1 wide range of
9-36VDC,18-75VDC,output over-voltage and short-circuit
protection. And all of them can meet CISPR22/EN55022
CLASS A without external circuit. Typical applications for these
converters are industrial, electric power, instrumentation,
telecommunication.

Note：
①
"X" means the model without Ctrl pin, series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example URB2405XD-10WR2A2S is
chassis mounting without Ctrl pin,URB2405D-10WR2A4S is DIN-Rail mounting with Ctrl pin;
②
Absolute maximum rating without damage on the converter;
③
For dual-output-converters the given value is for one output (for both outputs the same value);
④The
efficiency of "A2S" and "A4S" is approx. 2% lower.
