Trim output voltage up by connecting an external resistor between Pins 5 and 6. Use the following equation.

Reference Table 1 for variable A.

Example:

If we want to trim 5% up for 12V output units,

where A = 1.98,

Δ % = 0.05

Trim output voltage down by connecting an external resistor between Pins 5 and 7. Use the following

equation. Reference Table 2 for variable C and D.

Example:

If we want to trim 4% down for 5V output units,

where C = 1.24, D = 26.5,
