Accepts three PSM500 500W power suppliesPhihong USA has introduced a 1,500W 1U rack for RPS and bulk power sources. With quick-disconnect connectors for three individual loads, the new PSM1554 accepts three PSM500 500W power supplies. Applications include poe touts high efficiency" target=_blank>power-over-ethernet (PoE), voip phones, DC UPS, lighting systems with a single UPS, and network redundant power sources (RPS).

"The PSM1554 is unique in that it is PoE- and network RPS-compatible," said Keith Hopwood, VP of marketing for Phihong USA, in a statement. "Not only does it meet isolation requirements, but it is hot-swappable and configured for PoE midspans and 48V RPS input for switches."

The PSM1554 is available with 48V main up to 30A and standby 12V up to 4.5A, and operates from an input voltage of 90Vac to 264Vac, with active power factor correction. It is hotplug, n+1 configurable for scaleable and redundant applications. The new rack measures 17.25-by-13.77-by-1.75 inches, and weighs 2.5lbs.

Each output is individually protected against overloads, thus fully protecting the system against overload, over-temperature and over-voltage. It features diagnostic capabilities and LEDs next to each connector. The rack is also compliant with the IEEE 802.3af input voltage requirements.

The product is designed to allow for easy connection of a battery plant for full DC UPS capability for VoIP phone systems or network switches. A single battery plant can provide a UPS function for over 100 IP phones or a complete rack of network switches.

Typical pricing for the PSM1554 rack is $129 and less than $100 for 500W power modules in OEM quantities. Delivery is from stock to 10 weeks.
