A series of 3000W programmable AC/DC power supplies, designated the HDS3000 series, has been launched by XP Power. Complimenting the company's existing 800W and 1500W versions, the series comprises seven single output models providing all the popular nominal output voltages from + 12 to + 60 VDC.
These highly efficient supplies, up to 93%, 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 RS232 serial interfaces and analog controls include using a 0 to +5 VDC input voltage or by using an external resistor.
An output trim adjustment of +/- 5% of stated nominal via a potentiometer is also provided in order to compensate of 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 VDC / 0.5A or 9 VDC / 0.3A.
Despite its high output power, the HDS3000 has a high power density and is packaged in a chassis mount format measuring only 360.0 x 127.0 x 127.0 mm (14.7 x 5.0 x 5.0 inches) 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 overtemperature shutdown. Up to five supplies can be configured in parallel to provide a current share capability for increasing available power output or to build in redundancy into the end-system. A multicolour LED is used to indicate power supply operational status through a combination of colour and flashing or constant illumination.
With its universal input range of 90 – 264 VAC the HDS3000 is suitable for worldwide use. There is no derating until below 100 VAC. The supply complies with the internationally recognized UL/EN609501-1 safety standard for IT equipment and also meets Class A conducted and radiated EMI criteria as stipulated by EN55022.
The HDS3000 series is available from Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power and come with a 3 year warranty.
