Datasheet

Murata has announced the launch of the D1U86P series of ultra-high density power converters. Each power supply generates a main output of 12VDC with a 12VDC standby output for power management circuitry. The main DC output delivers up to 133.3A, with droop current sharing when parallelling multiple power supplies. Up to eight power supplies may be used in parallel for very high current applications.

With output ratings of 1600W for 180-264VAC inputs, 1350W for 108-264VAC and 1200W for 90-264VAC inputs, the converters provide higher power at low line levels when compared to competitors’ similar power supplies. They can achieve 94% efficiency at 50% load.

Designed for networking applications, storage, high performance computing and data centres, Murata’s D1U86P series power supplies are designed to fit 1U enclosures, and measure just 86x197.7 mm. High density packaging techniques provide a market leading 38W per cubic inch power density.

Again improving on competitors units, the converters’ offer a hold up time of 12ms, compared to competitors’ 10ms. 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 540,000 hours (as per Telcordia SR-322 M1C1 at 40°C) and use a standard C14 AC-input connector and a terminal block for DC-input for convenience and familiarity.
