Characteristic Curves

Output vs. Temperature

350W convection cooled and 500W continuous with 200 LFM airflow. Derate output power to 50% at 70°C.

Power_Good, DC_OK, Inhibit Signals and Current Sharing – J2

1.

Power_Good: - Output Signal – J2 Pin 6

During normal operation is Logic High, goes HIGH 100-250 ms after main output is in regulation, and goes LOW with 7ms warning time

before loss of main output due to loss of AC input.

Note: Power_Good signal is a combination of AC OK (Internal) and

DC_OK such that failure of either one will cause the Power_Good

signal to go low.

Logic High: >4.5V sourcing 16mA

Logic Low: <0.5V sinking 16mA

2.

DC_OK: Output signal – J2 Pin 10

During normal operation, this signal is logic High. It will go logic Low for output less than 90% of its nominal rated voltage.

Logic High: >4.5V sourcing 16mA

Logic Low: <0.5V sinking 16mA
