2
Number of outputs
-
1
Input voltage
nom. DC 12-28V ±30% The input circuitry must meet the SELV requirements
stipulated by IEC/EN/UL 60950-1.
Input voltage range
-
8.4-36.4Vdc
Voltage drop, input to output typ. 140mV
at 2x20A, see Fig. 3-1
typ. 72mV
at 2x10A, see Fig. 3-1
typ. 112mV
at 1x20A, see Fig. 3-2
Input current
nom. 2x 0-20A
continuous
nom. 2x 20-32.5A
for 5 seconds
max 2x 32.5A
at continuous overload or short circuit
Peak input current
max. 1000A
for max. 1ms per input
Output current
nom. 40A
continuous
nom. 40-65A
for 5 seconds
max. 65A
at continuous overload or short circuit
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
Note:
Ensure that the continuous output current does not exceed 65A. Check the short-circuit current of the power sources and if the
power source can deliver more than 65A together, use an appropriate fuse on the output.
