Measuring 101.6x152.4x42.4mm (4.00x6.00x1.67"), the GSP500 series of highly efficient 500W AC/DC power supplies has been introduced by XP Power. The single output forced air cooled units require just 12CFM thanks to its high efficiency design and an almost entirely flat efficiency curve over the whole load range.

Operating over a temperature range from -40 to +50°C (up to +70°C with derating), the GSP500 series is packaged in a U channel chassis mount format and available in three single output models providing the nominal outputs of +12, +24 or +48VDC. A +12VDC/0.3A fan output is provided and an integral end-mounted fan option (-EF) is available to order. The GSP500 has a peak power capability that can deliver up to 650W for a maximum of 100ms.

Incorporating a pair of three-speed fans, the fan speed is determined by a combination of internal ambient temperature, input voltage and output load. This ensures acoustic noise is always kept to a minimum. The unit is designed so the fans will shut down under all input conditions where the load is minimal, helping to prolong fan life. This suits medical applications where the end-equipment is located close to patients.

A +12VDC fan supply is available on the U-channel version and a +5VDC/2A always-on output is available to supply logic circuits. With convection cooling the standby output is still available and rated at 5W. The device can also provide an output power of up to 180W with convection cooling only.

The series conforms to the ANSI/AAMI ES60601-1 medical 3rd edition safety standard and also complies with the internationally recognised IEC/UL/EN60950-1 safety standard for IT equipment. Protection features and control signals include power fail, inhibit, output good LED and remote sense. 

The GSP500 series is available with a three year warranty.
