All parameters NOT specially mentioned are measured at 48, 96VDC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.

It indicates the output status of the PSU. It can operate in two ways : One is sinking current from external signal ; the other is sending out a voltage signal. 2-1 Sink current : The maximum sink current is 10mA and the maximum external voltage is 13V. 2-2 Voltage signal : Between O/P OK(pin3) and GND(pin4) +Vo +Vo -Vo -Vo +V ADJ.
