SHP650 / MHP650 Series AC-DC Power Supply

XP Power introduces 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 W per 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 minimizing noise. By using the U channel format designers can supply their own airflow; only 5.5 m per second forced airflow is required. A 12 V_DC, 6 W fan supply is provided when using this format.

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

Each series offers six output voltage variants covering the nominal voltages of 12, 15, 24, 28, 36, or 48 V_DC, and can be trimmed within +/- 10% of nominal. A 5 V_DC, 1 W 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.
