Press release date: December 19, 2013

Murata announced today the D1U86G series of 86 mm wide, 460 Watt front end power supplies from Murata Power Solutions. The D1U86G can achieve a high minimum conversion efficiency of 92 percent at 50 percent full load. With 1U form factor, these units measure only 86.0 x 196.9 x 39.9 mm, ideal for length-limited applications and mid-plane design architectures. The unit’s high efficiency significantly lowers the host system cooling requirements and also contributes to power savings in customer applications. The D1U86G series comprises two models, both providing a + 12 VDC 460 Watt output with either “back to front” or “front to back” direction of airflow . The power factor corrected D1U86G series accommodates the universal AC input range from 90 to 264 VAC. Forced air cooling is provided by an internal variable speed fan. The series features a 0 to 50 degrees C operating temperature range, without any derating due to line input or temperature.

The D1U86G series features hot-swapping and hot plug capability and droop current sharing for up to 8 supplies to be connected together.

Safety features include output overvoltage, output overcurrent, and self-resetting overtemperature protection. PMBus™ management and I2C interface with status indicators and boot loading are also available. An LED on the front panel indicates the operational status of the power supply. The D1U86G series design utilizes a low component count resulting in high reliability (MTBF 635K hours).

Typical applications for the D1U86G series include servers, storage sub-systems and data communications infrastructure equipment, workstations, storage devices, and other distributed power systems.

The D1U86G series complies with international safety standards IEC/EN/CSA/UL/CB.
