Positive Logic
To turn the module on and off, the user must supply a switch (or
equivalent circuit below) to control the voltage between the on/off
terminal V
the module is normally on. To turn the module off the voltage on
the V on/off pin needs to be 0V-1.2V. The maximum current I
should be limited to less than 100µA

Installation Data Sheet

The power module operates in a
variety of thermal environments;
however, sufficient cooling
should be provided to help
ensure reliable operation of the
unit. Heat is removed by
conduction, convention, and
radiation to the surrounding
environment. Proper cooling can
be verified by measuring the
case temperature. The case
temperature (Tc) should be
measured at the position indicated in figure to the right.
When operating the module, adequate cooling must be provided
to maintain the case temperature at or below 100°C. Maintaining
a lower temperature will yield higher reliability of the device.
Optimum cooling is obtained with forced convection.
