Contributing to power savings in customer applications, this high efficiency significantly lowers the cooling requirements. The design also offers at least 8% more power than leading competitors in the same form factor. Operating over a temperature range of 0 to 60 degrees C, the power factor corrected D1U54P series accommodates the universal AC input range from 90 to 264 VAC. An internal variable-speed fan provides forced air cooling.
The D1U54P series comprises two models, both providing a + 12 VDC 1200 Watt output and an auxiliary +5 VDC 15 Watt output. Allowing up to 8 supplies to be connected together, the D1U54P series features hot-swapping and active current sharing.
Safety features on the D1U54P include output overvoltage, output overcurrent, and self-resetting overtemperature protection. PMBus management and I2C interface with status indicators and boot loading are also available. Bi-Colour LEDs on the front panel indicate the status of the power supply. The D1U54P series design utilizes a low component count, resulting in high reliability and a MTBF of 529K hours.
Typical applications for the D1U54P series include data centers, servers, storage sub-systems, and data communications infrastructure equipment. The D1U54P series complies with international safety standards IEC/EN/CSA/UL BSMI and CCC 60950-1 for IT equipment.
