DATA SHEET SNAP Power Supplies Form 1120-150202 SNAP Power Supplies Features 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) SNAP Power Supplies Description SNAP power supplies provide the best source of AC or DC Each SNAP power supply can be mounted in one of two ways: power for your Opto 22 SNAP PAC hardware. Packaged in a next to the controller or SNAP I/O unit it powers, using the compact and sturdy housing, SNAP power supplies include a standard panel-mounting base, or directly on a DIN rail using built-in fuse, an LED status indicator, and an ON/OFF power the optional DIN-rail adapter. switch for ease of use. AC or DC input power connections, as required by the model, The SNAP-PS24 and SNAP-PS24U power supplies are are made to a removable terminal strip on top of the power designed for either of two purposes: supply. DC output power is then ready to be hooked up to the to provide primary power for a SNAP PAC S-series controller controller or rack using the attached wiring harness. to provide 24 volts of DC loop power for SNAP analog SNAP power supplies work with Wired+Wireless PACs and modules mounted on a SNAP PAC rack I/O units as well as standard wired PACs and I/O. The SNAP-PS5, SNAP-PS5-24DC, and SNAP-PS5U power Notes for legacy hardware: SNAP power supplies are also supplies are designed to provide 5 VDC power for a SNAP PAC compatible with Ethernet-based SNAP Ultimate, SNAP rack with an I/O processor (SNAP PAC brain or R-series Ethernet, and SNAP Simple I/O, and with serial-based SNAP controller) and I/O modules mounted on the rack. The I/O units such as those with a B3000, SNAP-HA, or combination of a rack, processor, and modules is called an I/O SNAP-B3000-MODBUS brain. unit. Part Numbers Opto 22 recommends using one SNAP power supply for each I/O unit and for each controller. Choose the power supply Part Description based on the load required for the I/O unit.

Additional SNAP Power Supply information on using power supplies can be found in the SNAP-PS5-24DC 24 VDC input 5 VDC, 4 A output Opto 22 technical note Using Power Supplies with Opto 22 SNAP Power Supply Systems (form 1271, available on our website, SNAP-PS5U 100250 VAC input 5 VDC, 5 A output www.opto22.com). SNAP Power Supply SNAP-PS24 All SNAP power supplies except the SNAP-PS5-24DC require 120 VAC input 24 VDC, 3/4 A output AC input power. The SNAP-PS5U and SNAP-PS24U SNAP Power Supply, 100250 VAC input SNAP-PS24U accommodate a wide range of AC input voltages, from 100 to 24 VDC, 1-1/4 A output 250 VAC. DIN-Rail Adapter for SNAP-PS5, SNAP- SNAP-PSDIN PS24, or SNAP-PS5-24DC The SNAP-PS5-24DC DC-to-DC power supply requires a 24 VDC input and is ideal for systems using DC backup power.

Local isolated power supply needs for your system. Copy the power supplies offer these advantages: requirements worksheet and complete one for each distributed I/O unit. Short supply conductors, which minimize losses Power redundancy, so the failure of a single supply causes In addition, keep the following power recommendations in only a single rack failure, not a total system failure mind.
