Note:
①series with suffix “A2S” are chassis mounting, for example URB1D05YMD-6WA2S is chassis mounting,
②Absolute maximum rating without damage on the converter, but it isn't recommended;
③The efficiency of A2S (wiring type) products is 2% lower than the above-mentioned value due to the reverse connection protection for input;
