The new HCP series of single output, compact bulk power ac dc power supplies from XP Power are typically up to 91% efficient. The four output power models include 650W and 1kW versions, which are both less than 1U high, and a 1.5kW and 3kW version. A single wire current share capability allows the configuration of multiple units to achieve a higher power output or to provide redundancy.
All the popular nominal output voltages from + 12 to +48Vdc are available across the range. To accommodate an even wider range of output voltage requirements, an output voltage trim capability allows adjustment of 30 - 105% of nominal output voltage. A similar function provides adjustment of current output between 40 - 105% of maximum current. Both controls can be made by using either an external voltage input or by a variable resistor. A +5Vdc 0.5A standby supply can be used to drive logic or control circuits without the need to design-in an additional voltage source or step down converters.
These fan cooled units are ideal for customers looking for a compact high efficiency power supply that has programmable features and monitoring signals. By varying the cooling fan speed depending on the output load fan noise is kept to a minimum. Monitor and control signals include DC OK, remote sense and remote on/off. A multifunction LED indicator gives a visual indication of the power supply's operational condition.
