Single-Output 500 W Power Supply measures 4 x 6 x 1.67 in.

Press Release Summary:

Employing two 3-speed fans, GSP500 series can continuously deliver full output power across -40 to +50°C and up to +70°C with derating. Nominal operation requires 12 cfm of forced air cooling, but up to 180 W output is possible with convection cooling only. Packaged in U channel chassis mount format, series include 3 models that provide nominal outputs of +12, +24, or +48 Vdc; +12 Vdc/0.3 A fan output is also provided.

Original Press Release:

Compact 500 Watt Power Supply Fits 4" x 6" Footprint for Medical and Industrial Applications

XP Power today announced the GSP500 series of highly efficient 500 Watt AC-DC power supplies. Occupying a compact 4 x 6 inch footprint these single output forced air cooled units can continuously deliver the full output power across the wide temperature range of – 40 to + 50 degrees C and up to +70 degrees C with derating. With its high efficiency design and an almost entirely flat efficiency curve over the whole load range the supply requires just 12 CFM of forced air cooling. The GSP500 can also provide an output power of up to 180 Watts with convection cooling only.

Measuring 4.00 x 6.00 x 1.67 inches (101.6 x 152.4 x 42.4 mm) and packaged in a U channel chassis mount format, the GSP500 series is available in three single output models providing the nominal outputs of +12, + 24 or + 48 VDC. A +12 VDC / 0.3 A fan output is also provided. An integral end-mounted fan option (-EF) is available to order. Incorporating two 3-speed fans, the fan speed is determined by a combination of internal ambient temperature, input voltage and output load, and ensures acoustic noise is always kept to a minimum.  In addition, the unit is designed so the fans will shut down under all input conditions where the load is minimal. This approach helps prolong fan life and also suits medical applications where the end-equipment is located close to patients.

The series conforms to the ANSI/AAMI ES60601-1 medical 3rd edition safety standard and also complies with the internationally recognized IEC/UL/EN60950-1 safety standard for IT equipment. Protection features and control signals include power fail, inhibit, output good LED and remote sense. A +12 VDC fan supply is available on the U-channel version and a +5 VDC / 2 A always-on output is available to supply logic circuits.  With convection cooling the standby output is still available and rated at 5 Watts.

The GSP500 has a peak power capability that can deliver up to 650 Watts for a maximum of 100 ms.

The GSP500 series is priced at $214.50 for 500 pcs orders of the U bracket model and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
