Input current
nom. 2x 0-10A
continuous
nom. 2x 10-16A
for 5 seconds
Peak input current
max. 1000A
for maximal 10ms per input
Output current
nom. 20A
continuous
nom. 20-32A
for 5 seconds
max. 26A *)
at continuous overload or short circuit
Reverse current
max. 4mA
per input, -40°C to +70°C
Reverse voltage
max. 45Vdc
voltage applied to the output, continuously allowed
*) Ensure that the continuous output current does not exceed 26A. Check the short-circuit current of the power sources and if the power
source can deliver more than 26A together, use an appropriate fuse on the output.
