Phihong has introduced a 500W 1U switching power supply with 1,500Vac output isolation and SELV output for applications such as Power-over-Ethernet, telecommunications, servers and network redundant power sources.

The PSM500-210, available with 48V or 12V main outputs and 12V standby output, operates from an input voltage range of 85Vac to 265Vac with active power factor correction and is hotplug n+1 configurable for scaleable and redundant applications. The PSM500 has integral cooling, current sharing, and standby 12V supply, and is fully protected against overload, over-temperature and over-voltage. It features diagnostic capabilities, front panel LEDs and optional isolation diodes. Three PSM500s can be loaded into a 1U, 19-inch rack for 1,500W.
