Pinout Description (cont)
T (Trim):
Allows fixed or variable adjustment of the module output.
Trimming Down: Allows output voltage of the module to be trimmed down, with a decrease in
efficiency. Ripple as a percent of output voltage goes up and input range widens since input
voltage dropout (loss of regulation) moves down.
Trimming Up: Reverses the above effects.
–S, +S (–Sense, +Sense):
Maintains specified output voltage to the load. Overvoltage protection will be activated in the
VI-200/MI-200 and module will shut down if remote sense tries to boost output voltage above
110% of nominal. Do not exceed 0.25V drop in negative return; if the voltage drop exceeds
0.25V in the negative return path, the current limit setpoint will increase. Connect + sense to
+ out and –sense to –out at the module if remote sensing is not desired (see figure 4, pg 9-2).
