Connectors
OuTPuTS (CN1)
CN1 contains the output connectors. Note that CN1-3 and CN1-4 are for future use. The galvanically
isolated outputs offer +3.3VDC @ 8A maximum and +5VDC @ 17A maximum. The combined total
power for both outputs is 85W. Please see the Technical Notes section for more information. The
quick-disconnect screw terminal blocks are intended for 28 to 16 AWG wires.
Note
The terminal socket is Phoenix
1803358 which mates with screw
terminal block plugs, Phoenix
1827787
CAuTION
There is an addi5VDC and
ISOCOM connector to adequately
distribute the current if a heavy
load requires more than 8A (max.
rating of terminal block)

The Shutdown (SDin) input is an active high opto-coupled input which remotely controls the output
on/off operation. It acts like an ignition input for vehicle applications. The input range is +9V to +33V
DC. The quick-disconnect screw terminal block is intended for 28 to 16 AWG wires.
