PC42 Dual Power Supply
PC42
The PC42 dual regulated
power supply is designed for
applications in which a magmeter
is used together with a 4-20 mA
transmitter such as the AO55
or FT440. Although a single 24
Vdc power supply can be used,
there is a risk of a ground loop
interfering with proper operation
of the 4-20 mA current loop. This
risk is eliminated by the dual power supply.
The housing is rugged molded ABS plastic, NEMA 4X rated.
It can be wall or panel mounted. The PC42 can be hardwired
to the AC main supply or plugged into a standard outlet
using the included power cord. Inside there are separate
terminals to connect the two devices to the fully isolated
supplies.
Installation and Connections
Remove the cover to expose the four mounting holes at the
bottom of the cover screw tubes. Mark the mounting surface,
drill, and attach with screws. Do not drill additional holes in
the box. Doing so will allow moisture into the enclosure.

Caution 1: Important! Do not connect power to
the PC42 until all connections have been made and
conrmed correct, and the cover has been put back into
place.
Caution 2: It is essential for safety and proper operation
to use a ground connection for the 115 Vac power. Do
not use this power supply without proper grounding.

Power Supply
PC3
The PC3 is designed as a
convenient 24 Vdc power
supply for use with a 120
Vac outlet. Terminals allow
user connection of wiring on
the low-voltage side. Since
this is an unregulated power
supply, actual voltage may be
as high as 36 Vdc, depending
on line voltage and load. The
PC3 should be used only in
applications where these
voltages are tolerated.
