XP Power announced the HDS3000 series of 3000 Watt programmable AC/DC power supplies, comprising seven single-output models providing all the popular nominal output voltages from +12 to +60 V d.c. With efficiency up to 93%, they allow the output voltage or output current to be programmed from 0% to 105% of nominal output by a variety of means.
Digital communication can be made via I²C or RS-232 serial interfaces and analog controls include a 0 to +5 V d.c. input voltage or an external resistor. An output trim adjustment of ±5% of stated nominal via a potentiometer is also provided in order to compensate for wiring losses, or to accommodate a non-standard voltage requirement. An always-on standby output is also available and is user selectable between either 5 V d.c. / 0,5 A or 9 V d.c. / 0,3 A.
Despite its high output power, the HDS3000 is packaged in a chassis mount format measuring only 360 x 127 x 127 mm, including the bus bar output connectors and the variable speed fan. Using a variable speed fan helps keep energy consumption to a minimum, reduces acoustic noise when operating at low load conditions, and extends the lifetime of the fan.
Signal and other control functions include remote on/off, AC OK, remote sense and over-temperature shutdown. Up to five supplies can be configured in parallel to provide current share capability for increasing available power output or to build redundancy into the end system. A multicolour LED is used to indicate operational status through a combination of colour and flashing or constant illumination.
With its universal input range of 90 – 264 V a.c. the HDS3000 is suitable for worldwide use. There is no derating until below 100 V a.c. The supply complies with the internationally recognised UL/EN609501-1 safety standard for IT equipment and also meets Class A conducted and radiated EMI criteria as stipulated by EN55022.
