Note: ① Series with suffix “H” are heat sink mounting, for example VRB2405LD-30WHR2. series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail
mounting, for example VRB2405LD-30WR2A2S is chassis mounting, VRB2405LD-30WR2A4S is DIN-Rail mounting. 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.
