Datasheet

Achieving a minimum conversion efficiency of 92% at 50% full load, the D1U86G AC/DC power supply from Murata is suitable for length-limited applications and mid-plane design architectures. The D1U86G series comprises two models, both providing a + 12VDC 460W 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 264VAC. Forced air cooling is provided by an internal variable speed fan, with the series featuring a 0°C to 50°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).

With a 1U form factor, these units measure only 86.0 x 196.9 x 39.9 mm making them suitable for applications including 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.
