XP Power Low Profile 1500W AC-DC Power Supply Suits Industrial Bulk Power Applications
XP Power announced the HPU1K5 1500W 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, or + 48 Vdc, with each being user adjustable either manually, or via an external voltage signal. The universal input range covers 85-264Vac, with output power up to 1500W available at high line input and up to 1200W when using input voltages below 180Vac.
Using an integral fan, the supply can be mounted either vertically or horizontally and will operate in a wide temperature environment from -20 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 units 90%+ power efficiency.
The HPU1K5 can be used utilised in current share designs where up to 8 of the same output voltage models can share current within 10% of each other at full load.
A 5V/1A standby rail is standard. Other control lines and signals provide AC OK, DC OK, Inhibit, Enable, Fan Fail and overtemperature indications. Remote sense compensates for up to a 0.5V drop in the connection cabling. All models have international safety agency approvals and meet the required conducted and radiated noise levels.
The HPU1K5 series is priced at $507 each in 500 unit quantities.
