Digital-bus AC-DC power supply achieves 92% efficiency at 50% full load
The unit’s high efficiency significantly lowers the host system cooling requirements and also contributes to power savings. The D1U86G series comprises two models, both providing a +12 VDC 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 264 VAC. Forced air cooling is provided by an internal variable speed fan. The series features a 0 to 50C 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 uses a low component count resulting in high reliability (MTBF 635K hours) and complies with international safety standards IEC/EN/CSA/UL/CB.
