The PSA 160 series open frame power supply offers up to 160-W and suits IT and multimedia applications. The 2 × 4-in. supply is available in 12-, 24-, 48- and 56-Vdc outputs and is used in 1U racks for a variety of networking applications. The power supply features over-voltage, over-current and short-circuit protection, with cUL/UL and CE safety approvals. In the event of a voltage surge or over-load, the unit automatically restarts while the output can be shorted permanently without damage. Operating temperatures for the power supply are -20° to +70℃, load de-rating at 45℃ with forced air cooling enabled and at 40℃ without fan cooling. Without the addition of 12.6-cfm forced air cooling, the output rating is reduced to a maximum of 90 W.
