APPLICATION
URA_YMD-6WR2&URB_YMD-6WR2
series
models
provide 6 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 Series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example URB2405YMD-6WR2A2S is chassis mounting ,
URB2405YMD-6WR2A4S is DIN-Rail mounting.
②Absolute
maximum rating without damage on the converter,but it isn't recommended.
③For
dual output converter, the given value is the same for each output.
④The
efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.
