Resistor

Output Over Voltage Protection:

The output voltage is monitored by a redundant

secondary-side circuit. If the output voltage exceeds the

over-voltage specification, the microprocessor will

restart every 2 seconds and limit voltage with a separate

reference circuit. This advanced feature prevents the

converter from damaging the load if there is a converter

failure or application error.

Latching is available as an option.

Over Current Protection:

If overcurrent lasts more than 3 seconds the converter

will shut down and try to restart every 10 seconds until

the fault is removed.

Latching is available as an option.

Thermal Shutdown:

The printed circuit board temperature is measured

using a semiconductor sensor. If the maximum rated

temperature is exceeded, the converter is turned off. It

will then restart every 2 seconds.

Latching is available as an option.

Remote Sense:

The output voltage is regulated at the point where the

sense pins connect to the power output pins. Total sense

compensation should not exceed 1V. A negative sense

lead is connected internally.

Safety:

An external input fuse must always be used to meet

these safety requirements.
