SNAP Power Supplies

Description
SNAP power supplies provide the best source of AC or DC
power for your Opto 22 SNAP PAC hardware. Packaged in a
compact and sturdy housing, SNAP power supplies include a
built-in fuse, an LED status indicator, and an ON/OFF power
switch for ease of use.
The SNAP-PS24 and SNAP-PS24U power supplies are
designed for either of two purposes:
• to provide primary power for a SNAP PAC S-series controller
• to provide 24 volts of DC loop power for SNAP analog
modules mounted on a SNAP PAC rack
The SNAP-PS5, SNAP-PS5-24DC, and SNAP-PS5U power
supplies are designed to provide 5 VDC power for a SNAP PAC
rack with an I/O processor (SNAP PAC brain or R-series
controller) and I/O modules mounted on the rack. The
combination of a rack, processor, and modules is called an I/O
unit.
Opto 22 recommends using one SNAP power supply for each
I/O unit and for each controller. Choose the power supply
based on the load required for the I/O unit. See the power
requirements tables starting on page 11 for help in
determining the power supplies you need. Additional
information on using power supplies can be found in the
Opto 22 technical note Using Power Supplies with Opto 22
Systems (form #1271, available on our website,
www.opto22.com).
All SNAP power supplies except the SNAP-PS5-24DC require
AC input power. The SNAP-PS5U and SNAP-PS24U
accommodate a wide range of AC input voltages, from 100 to
250 VAC.

AC or DC input power connections, as required by the model,
are made to a removable terminal strip on top of the power
supply. DC output power is then ready to be hooked up to the
controller or rack using the attached wiring harness.
SNAP power supplies work with Wired+Wireless™ PACs and
I/O units as well as standard wired PACs and I/O.
Notes for legacy hardware: SNAP power supplies are also
compatible with Ethernet-based SNAP Ultimate, SNAP
Ethernet, and SNAP Simple I/O, and with serial-based SNAP
I/O units such as those with a B3000, SNAP-HA, or
SNAP-B3000-MODBUS brain.

DATA SHEET

SNAP-PS5

Form 1120-121221

The SNAP-PS5-24DC DC-to-DC power supply requires a 24
VDC input and is ideal for systems using DC backup power.

Each SNAP power supply can be mounted in one of two ways:
next to the controller or SNAP I/O unit it powers, using the
standard panel-mounting base, or directly on a DIN rail using
the optional DIN-rail adapter.

SNAP Power Supplies

Built-in fuse, ON/OFF power switch, and LED indicator
Convenient panel mounting; optional DIN-rail
mounting
Easy connections
Wide input voltage range
Factory Mutual approved (except SNAP-PS5U and
SNAP-PS24U)
