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 5 Volt / 1 Amp 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 0.5 V drop in the connection cabling. All models have international safety agency approvals and meet the required conducted and radiated noise levels.
The HPU1K5 series comes with a 3 year warranty and is available from Farnell or direct from XP Power.
