Low-profile 1500 W power supplies

20 January 2010 Power Electronics / Power Management

XP Power has launched the HPU1K5 1500 W AC-DC power supply series aimed at a broad range of industrial applications that require bulk power within a compact enclosure. Three


single-output models are available covering the nominal output voltages of +12, +24 and +48 V d.c., with each being user adjustable either manually or via an external voltage signal. The universal input range covers 85–264 V a.c., with output power up to 1500 W available at high line input and up to 1200 W when using input voltages below 180 V. Using an integral fan, the supply can be mounted either vertically or horizontally and will operate in a wide temperature environment from -20°C up to +50°C at full power, and up to +70°C with derating.

The mechanical design of the HPU1K5 includes a number of innovative design features, such as use of a variable speed fan to keep audible noise to a minimum, and the use of only two internal PCBs. These features aid the optimal flow of air through the unit, helping to maintain a low internal operating temperature and ensuring long-term component reliability. The use of a dual stage power factor correction (PFC) circuit and synchronous rectification techniques contribute to the unit’s 90%-plus power efficiency.

The HPU1K5 can be utilised in current share designs where up to eight of the same output voltage models can share current within 10% of each other at full load. A 5 V/1 A standby rail is standard. Other control lines and signals provide AC OK, DC OK, Inhibit, Enable, Fan Fail and over-temperature indications. Remote sense compensates for up to a 0,5 V drop in the connection cabling. All models have international safety agency approvals and meet the required conducted and radiated noise levels.
