AC-DC Power Supplies Are Compact, Offer High EfficiencyXP Power offers the HCP series of single output compact bulk power AC-DC power supplies. These highly efficient units, typically up to 91%, comprise four output power models: a 650 W and 1.0 kW, which are both less than 1 U high, and a 1.5 and 3.0 kW. 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 48 VDC are available across the range. To accommodate an even wider range of output voltage requirements, an output voltage trim capability allows adjustment of 30% to 105% of nominal output voltage. A similar function provides adjustment of current output between 40% to 105% of maximum current. Both controls can be made by using either an external voltage input or by a variable resistor. A 5 VDC 0.5 A 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.
