Open Frame Power Supply Delivers 160W

Tue, 12/20/2011 - 5:04am
PSA160 seriesPhihong USA has announced a new standard open frame power supply that offers up to 160W for IT and multimedia applications. Designated the PSA160 series, the 2" x 4" PSU is available in 12V, 24V, 48V and 56V DC outputs and is ideal for use in 1U racks for a variety of networking applications.

“The PSA160 series is designed for devices that require more power in a small form factor for applications like cable TV,” said Keith Hopwood, vice president of marketing for Phihong USA. “The power supplies’ low-cost, high-power output and small footprint allow OEMs to fit a lot of power in a limited space.”

The PSA160 series 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 will automatically restart while the output can be shorted permanently without damage. Operating temperatures for the power supply are -20°C to +70°C, load de-rating at 45°C with forced air cooling enabled and at 40°C without fan cooling.

To achieve full power at 160W, the unit must be fan cooled. Without the addition of 12.6 CFM forced air cooling, the output rating is reduced to a maximum of 90W. The PSA160 has high efficiencies between 86-88% at 115VAC input and at 88-90% with 230VAC input.

The power supply measures 101.6mm by 50.8mm by 34.5mm and weighs 185g for the 12V model and 195g for the remaining models in the series. Typical OEM pricing for the PSA160 will start at $91.07 in single unit quantities.
