Positive Logic
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.
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

Installation Data Sheet
External Trim (output voltage
adjustment)
Output voltage set point adjustment allows the user to increase or
decrease the output voltage set point of a module. This is
accomplished by connecting an external resistor between the TRIM
pin and either the (+)Vout or (-)Vout pins. With an external resistor
between the TRIM and (+)Vout pin, the output voltage set point
decreases. With an external resistor between the TRIM and (-)Vout
pin, the output voltage set point increases.
