and C values are defined in Table 1. For example, to trim-
down the 24V module (VHB200W-Q24-S24) by 8% to
22.08V, R
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. Care should be
taken to ensure that the maximum ouput power of the module remains at or below the maximum rated power (Maximum rate power =
V
To trim the output voltage with fixed resistors, the output voltage can be calculated as follows.
