Murata Power Solutions has unleashed the D1U86P series of ultra-high density power converters. The 1.6kW rated power supplies flaunt AC-input and DC-input models, and are engineered to fit 1U enclosures. Measuring 86mm x 197.7mm, the devices feature high density packaging techniques to deliver 38W per cubic inch power density.

Each D1U86P power supply generates a main output of 12VDC. There is also a 12VDC standby output for power management circuitry. The main DC output delivers up to 133.3A, with droop current sharing when paralleling multiple power supplies. Up to eight power supplies may be used in parallel for very high current applications up to and beyond 1kA.

With output ratings of 1.6kW for 180VAC to 264VAC inputs, 1.35kW for 108VAC to 264VAC, and 1.2kW for 90VAC to 264VAC inputs, the converters claim to provide higher power at low line levels when compared to competitors' similar power supplies. The D1U86 series achieves 94 per cent efficiency at 50 per cent load.

Again improving on competitors' units, the converters offer a holdup time of 12ms, compared to competitors' 10ms, stated Murata. Simplifying design, the D1U86P series uses the same form factor for AC or DC inputs, and both models are available for any airflow type. Exhibiting high reliability, the converters' MTBF exceeds 540khr as per Telcordia SR-322 M1C1 at 40C, and for convenience and familiarity they use a standard C14 AC-input connector and a terminal block for DC-input.

Targeted for networking applications, storage, high performance computing and data centres, the D1U86P series uses the very latest power switching technology and high density component packaging techniques, added Murata. It offers the highest power density in the market, high current 12V power up to 133A, minimum holdup time of 12ms, industry-standard PMBus communications protocol, and a high MTBF, indicated the company.

Samples are available from stock. Lead-time is 14 weeks. Pricing in OEM quantities is $243.56.
