Note:
①series
with suffix
“H”
are heat sink mounting; series with suffix
“A2S”
are chassis mounting，with suffix
“A4S”
are DIN-Rail mounting,
for exampleURB1D05LD-20WHA2S is chassis mounting of with heat sink,URB1D05LD-20WA4S 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;
③The
efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.
