Application Notes:

Astrodyne SuperverterApplication note

Remote sense and trim functions
To use the remote sense, connect the "Sense +" and "Sense -" pins to wires that go to the load and don't carry any current. This lets the DC converter stabilize the voltage at the load, compensating for voltage loss in the wires that carry current.
In other words, without using the "Sense" terminals the voltage will be stabilized at the converter output terminals. As the current flows through wires, connectors, and contacts then resistance of these elements will cause a voltage drop due to Ohm's law. If you run an extra set of wires from the sense terminals to the load that don't carry current, then these can be used to sense the actual voltage at the load and the converter will boost its voltage to compensate for this voltage drop (over a limited range, ±0.5 Volts.)

The sense terminals can also be used to trim the voltage with fixed resistors or a pot as follows:
How to arrange the trimpot.

Schematic of how to trim the output voltage.


NOTE! these faceplate temperatures are definitely in the "burn your fingers" category and care should be taken to prevent human contact.
