XP Power today announced the introduction of the SHP650 and MHP650 series of single output high power density fan cooled AC/DC power supplies.

The MHP650 range meets the IEC60601-1 safety specification for medical equipment while the SHP650 range compiles with the IEC60950 standard for IT and industrial equipment. Both series are highly efficient, typically 86%, and have a high power density of 8.2 Watts/cubic inch.

Three mechanical mounting formats are available to provide design-in flexibility. Two fan-cooled formats provide the option of having the fan mounted internally on the top or externally mounted on the end of the unit. The integral fan speed is load dependent to aid minimising noise. By using the U channel format designers can supply their own airflow; only 5.5 metres/second forced airflow is required. A +12 VDC, 6 W fan supply is provided when using this format.

All units operate from a universal 85-264 VAC input range with full power available from 90 VAC. The operating temperature range is -20 ºC to +70 ºC with no derating below 50 ºC.

Each series offers six output voltage variants covering the nominal voltages of +12, +15, +24, +28, + 36 or +48 VDC, and can be trimmed within +/- 10% of nominal. A +5 VDC, 1W always on output is also provided for standby purposes. The SHP and MHP ranges feature a constant current overload characteristic making them suitable for motor and other industrial type loads.

Available control signals include AC OK and remote on/off. An active current share capability is also provided to allow sharing of load across multiple units or for configuration of redundant systems, remote sense is also provided.

Both the SHP and MHP are of rugged construction with screw terminals and a 3 year warranty.

The units are available from our distributors or direct from XP Power.
