IMA-x400-xx

Current Share Bus Pin

J3 Pin 11

(CURRENT SHARE_V)

Voltage at CS Pin will vary linearly with load current on main output, and will be

6 V at rated load current, when the output voltage is at its rated value.

Power Good Pin

J3 Pin 9

(PWR_GOOD)

Open collector. As soon as AC input voltage and DC output voltage are in the

predefined range, the PWR_GOOD signal is set to HIGH.

Green LED

Will turn ON as soon as PWR_GOOD signal is set to HIGH
