BBS-2003_1 Datasheet, PDF (16/16 Pages) BOSER Technology Co., Ltd – 2U High, Small Box Bare Bone System

4.1.3 General Features
Efficiency: The efficiency is 70% typical while measuring at nominal line
and rated load
Hold up time: The hold up time is longer than 16mS at 115VAC input and
rated load, which is measured from the end of the last charging pulse to
when the main output drops down to 95% output voltage
Protection: For some reason the power supply fails to control itself, the
build-in over voltage protection circuit will shut down the outputs to prevent
damaging external circuits. The trip point of crowbar circuit is around
5.7~7.0V. The power supply will go into latch-off mode against short circuit
or over load conditions, and have to OFF and ON the AC input to restart the
power supply
4.1.4 Environmental Specifications
Temperature: 0~50°C (operating); -40~+85°C (storage)
Altitude: Will operate properly at any altitude between 0~10,000 ft
