Datasheet

A series of fan-cooled, rugged AC/DC power supplies has been launched, designed for heavy-use industrial applications where a more robust unit is required. The HHP650 series, from XP Power, can accommodate an extended voltage input range from 85 – 305VAC and deliver up to 780W at high line input.

The single output 650W power supply has a peak power capability that provides up to 800W at low line and 1000W at high line, for a maximum of 10 seconds. Conforming to the MIL-STD-810F shock and vibration specification, the series can withstand a 6kV surge as defined by IEEEStdC62.41. Further to this, the power supply has immunity to voltage sag, as stipulated by semiconductor manufacturing standard SEMI-F47, and benefits from conformal coating. The units are also certified against the safety standard for industrial control equipment UL508, international safety standard UL/EN/IEC 60950, and the specification for equipment used in hazardous locations ANSI/ISA12.12.01-200 (previously UL1604).

Typically 85% efficient, the device features an operating range from -40°C to +70°C, with no derating until +50°C. The device has an internal end mounted variable speed fan and measures 253.8 x 106.8 x 63.5mm. The six models of the series provide popular nominal output voltages from +12 to + 48VDC, as well as featuring a trim function providing adjustment of ± 10% from stated nominal output. This caters 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 overtemperature. Single wire current sharing can also be incorporated when addition output power is required, or to build in redundancy. A DC OK volt free relay is also included.

The HHP650 is available with a 3 year warranty.
