SC-2345/2350 Carrier User Manual
SCC-PWR03
The SCC-PWR03 converts an external voltage of 7 to 42 VDC to +5 V and
±15 V and requires an external user-supplied DC power source. Attach the
voltage source to the screw terminals of J1 on the SCC‘-PWR03. Wire the
positive lead to the screw terminal labeled
7–42 V
and wire the negative
lead to the screw terminal labeled
GND
. If you are using the SC-2345
carrier, pass the leads through the strain relief on the front of the enclosure.
If you are using an SC-2345/2350 carrier with configurable connectors, use
a strain-relief panelette for the leads. You can power the SCC-PWR03 with
any appropriate 7 to 42 VDC source.
