Output Overvoltage Protection
To provide protection in an output overvoltage condi-
tion, the unit is equipped with circuitry that moonitors
the voltage on the ouput terminals. If the voltage on the
output terminals exceed the overvoltage protection
threshold, the module enters a hiccup mode of opera-
tion whereby it shuts down and automaticall attempts
to restart. As long as the fault persists, the module
remains in this mode.
The protection mechanism is such that the unit can
continue in this condition until the fault is cleared.
A latch-off option is also available.*

*Protection latch-off causes the ouput to be disabled until input
power is recyeled or until the remote on-off is recycled off-on.

Overtemperature Protection
To provide protection in a overtemperature condition,
the unit is equipped with an overtemperature circuit. In
the event of such a fault, the module enters into a hic-
cup mode of operation whereby it shuts down and
automatically attempts to restart. As long as the fault
persists, the module remains in this mode.
The protection mechanism is such that the unit can
continue in this condition until the fault is cleared.
A latcho-off option is also available.*
Thermal Considerations
Introduction
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the unit are ther-
mally coupled to the case. Heat is removed by conduc-
tion, convection, and radiation to the surrounding
environment. Proper cooling can be verified by mea-
suring the case temperature. Peak temperature (T
occurs at the position indicated in Figure 23.
Note: Top view, pin locations are for reference only. Measurements
Figure 23. Case Temperature Measurement
The temperature at this location should not exceed
100 °C. The output power of the module should not
exceed the rated power for the module as listed in the
Ordering Information table.
Although the maximum case temperature of the power
modules is 100 °C, you can limit this temperature to a
lower value for extremely high reliability.
