Murata has introduced the D1U54P series of 54mm wide 1.2kW front end power supplies from Murata Power Solutions. Flaunting efficiency of more than 94 per cent and a power density in excess of 28W/in3, the low profile units measure only 54.5 x 321.5 x 40mm and fit the industry standard 1U package format, stated the company. This efficiency claims to remarkably lower the cooling requirements and also contributes to power savings in customer applications.

According to Murata, the design offers at least eight per cent more power than leading competitors in the same form factor. The D1U54P series comprises two models, both providing a 12VDC 1.2kW output and an auxiliary 5VDC 15W output. The power factor corrected D1U54P series accommodates the universal AC input range from 90-264VAC. Forced air cooling is provided by an internal variable-speed fan. The series features a 0C to 60C operating temperature range.

The D1U54P series features hot-swapping and active current sharing for up to eight supplies to be connected together. Safety features include output over-voltage, output over-current and self-resetting over-temperature 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 uses a low component count, resulting in high reliability (MTBF 529K hours).

Typical applications for the D1U54P series include data centres, 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.

Pricing in production quantities for the D1U54P series is $270 per unit.
