Note:
①Series with suffix “H” are heat sink mounting; series with suffix “A2S” are chassis mounting,with suffix “A4S” are DIN-Rail mounting, for example
URB1D05LD-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, but it isn't recommended;
③The efficiency of A2S (wiring type) and A4S (rail type) products is 2% lower than the above-mentioned value due to the reverse connection protection for
input;
