7. OUTPUT TRIMMING (OPTIONAL)
The output voltages are preset to nominal values as indicated by the models table at the factory. If desired, the output voltage may
optionally be trimmed to a different value (+/- 10%) with external resistors and/or potentiometer as shown below.
To trim the output voltage with fixed resistors, the output voltage can be calculated as follows.
R1 and R2 are internal to the unit and are defined in Table 1.
the nominal output voltage. Vo is the desired output voltage.
For example, to trim-up the output voltage of 5.0V module
(VHB150W-Q48-S5) by 8% to 5.4V, R
