I-PS24 (POWER SUPPLY)
Installation & Operation Instructions
GENERAL INFORMATION
The
I-
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
I-
PS24 is setup for
Half-wave rectification from factory, but can be set to
Full-wave rectification via jumpers.
MOUNTING
I-
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 I-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 I-PS24 power supply is mounted within the same control panel.
