3)
for max. 5 seconds
max.
26A in overload /short-circuit (voltage < 6V). Ensure that the
sum of input currents does not exceed this value.
Reverse current max. 1mA at 24V, per input, -40°C to +70°C
Reverse voltage max. 40Vdc voltage applied to the output, continuously allowed
Output capacitance typ. 320μF
1) Ensure that the sum of both input currents stays below 24A rsp. 20A.
2) Ensure that the sum of both input currents stays below 32.5A.
3) The average value (R.M.S. value) of the output current must not exceed the values of the continuous output current.
