Note:
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-
15WHR2A2S is chassis mounting of with heat sink,URB2405LD-15WR2A4S 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;
③For
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 for the protection of inverse polarity.
