The final equipment must be re-confirmed that it still meets EMC directives.

Over Voltage Protection DC output power Overload Voltage Tolerance Hold up time Set up For all models hiccup mode, recovers automatically after fault condition is removed. For all models. Model B is 2%, 1% for all other models 12VDC/24VDC/48VDC at full load For all models 50 Watts 105~160% 50 2.5s mS Protection Circuit Parameter Input Fuse Overload Short circuit Output Over-voltage Over temp. Conditions/Description Built-in ac fuse. A blown fuse usually indicates permanent damage to the power supply serviceable by factory only. Current limiting starts at 110-140% of the rated output current in foldback mode and recovers automatically. Short circuit can be continuous. Recovers automatically upon removal of short. Output is protected agaist overvoltage. Unit shuts down and latches when voltage at output terminals exceeds 130%. AC input needs to be reset to restart the power supply. Power supply shuts down when temperature is in excess of 85 C. Auto recovery.
