BCD.00186_AD

The Out-OK output gives a status indication of the converter and the output voltages. It can be used for control functions

such as data protection, central system monitoring or as a part of a self-testing system. Connecting the Out-OK as shown

in

Note: using the potentiometer, the monitor level tracks the programmed output voltage. In an error condition, if the output

voltage is out of range due to overload or an external overvoltage, Vok will approach Vp. The output is formed by an NPN

transistor. The signal is isolated from the output.

Power Good Signal Description:

1.

O/P V OK – Signal Low, Opto conducting, (max sink current 0.5 mA)

2.

O/P V Bad – Signal High, Opto opening, (max leakage current 25

μA)

IMMUNITY

Note: Most of the immunity requirements are derived from EN 55024:1998/A2:2003.
