Note: ① Series with suffix “H” are heat sink mounting, series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example
URB2405YMD-20WHA2S is chassis mounting with heat sink, URB2405YMD-20WA4S is DIN-Rail mounting 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.
③The efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.
