Fan-cooled AC-DC Power Supplies
XP Power today announced the HHP650 series of fan-cooled rugged AC-DC power supplies designed for heavy-use industrial applications where a more robust unit is required. These single output 650 Watt units can accommodate the extended voltage input range from 85 305 VAC, and can deliver up to 780 Watt at high line input. In addition, the HHP650 has a peak power capability that provides up to 800 W at low line and 1000 W at high line for a maximum of 10 seconds. Suitable for use in the most demanding of industrial environments, the HHP650 conforms to the shock and vibration specification of MIL-STD-810F, has immunity to voltage sag as stipulated by semiconductor manufacturing standard SEMI-F47 and can withstand a 6 kV surge as defined by IEEEStdC62.41.
The units are also certified against the safety standard for industrial control equipment UL508, international safety standardUL/EN/IEC 60950, and the specification for equipment used in hazardouslocations ANSI/ISA12.12.01-200 (previously UL1604). The power supplies also benefit from conformal coating. Operating temperature range suits most industrial environments and is from -40 degrees to +70 degrees C, with no derating until +50 degrees C. The compact high efficiency HHP650, typically 85% efficient, has an internal end mounted variable speed fan and measures 10 x 4.2 x 2.5 inches (253.8 x 106.8 x 63.5 mm). The HHP650 series comprises six models providing the popular nominal output voltages from +12 to + 48 VDC. A trim function provides the adjustment of +/- 10% from stated nominal output in order to cater for non-standard voltage requirements. An auxiliary always on output of +5 V/ 0.2A can be used to power logic and memory functions. Protection and control signal features include DC OK, remote on/off, remote sense, overvoltage, short circuit and over temperature. Single wire current sharing can also be incorporated when additional output power is required, or to build in redundancy. A DC OK volt free relay is also included.
