OUTPUT VOLTꢀGE ꢀDJUSTMENT (2100 SERIES - DUꢀL OUTPUT)
The converter’s output voltage may be trimmed by up to ±10% of the nominal output voltage.
TRIM UP (Case ꢀ)
Trim output voltage up by connecting an external resistor between Pins 5 and 8. Use the following
equation, reference Table 1 for variables ꢀ.
