Note:
①."X"
means the model without Ctrl pin, series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example VRB2405XD-10WR2A2S is
chassis mounting without Ctrl pin,VRB2405D-10WR2A4S is DIN-Rail mounting with Ctrl pin.
②.Absolute
maximum rating without damage on the converter, but it isn't recommended.
③.The
efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.
④.For
dual output converter, the given value is the same for each output.
