GENERAL INFORMATION
The A/PS24 adjustable power supply is a low
cost, dependable external power supply. This
unit will accept an input of up to 26 VAC or 36
VDC, and provides an adjustable 1.5 to 26 VDC
output. Field voltage adjustment is done by
adjusting a potentiometer using a flat-head
screwdriver. The A/PS24 is setup for Half-wave
rectification from factory, but can be set to
Full-wave rectification via jumpers.
MOUNTING
PS24 is supplied with a snap track for
mounting. The circuit board may be mounted
in any position. In equipment / electrical
compartments, mounting upside down at top
of the enclosure is not recommended as heat
build-up could be a problem when running
higher current loads.
Use only fingers to remove board from snap
track. Slide out of snap track or push against
side of snap track and lift that side of the
circuit board to remove. Do not flex board or
use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect or disconnect wiring with power applied.
• All wiring must comply with local and National Electric Codes.
• It is recommended you use an isolated UL-listed class 2 transformer when powering the unit
with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may
result in damage to any device powered by the shared transformer.
• In applications where a Pilot Duty or remote relay is required, the A/DO008 transorb can be
placed across the coil of the relay to snub electrical spikes when the relays are de-energized. An
external transorb may not be required if the relay and PS24 power supply is mounted within the
same control panel.
