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-PS5U power supply is 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. Choose the power supply based on the load required for the I/O unit. Each SNAP power supply can be mounted in one of two ways: next to the SNAP I/O unit it powers, using the standard panel-mounting base, or directly on a DIN rail using the optional DIN-rail adapter. AC input power connections 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 I/O units as well as standard wired 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, B3000-B, SNAP-HA, or SNAP-B3000-MODBUS brain.
