Under normal operation, the dc source senses the output voltage at the output terminals on the back of the unit. External sense terminals are available on the back of the unit that allow the output voltages to be sensed at the load, compensating for impedance losses in the load wiring. You cannot remote sense at the optional front panel binding posts.

The output terminal block of the unit is shipped configured for local sensing, with the +S terminal jumpered to +, and the − S terminal jumpered to − . Remove these jumpers when making your sense wire connections. The terminal block screws are 6-32 X 3/8 inch.

Sense Leads

The sense leads are part of the dc source's feedback path and must be kept at a low resistance (less than several ohms) to maintain optimal performance. Connect the sense leads carefully so that they do not become open-circuited. If the sense leads are left unconnected or become open during operation, the dc source will regulate at the output terminals, resulting in a 3% to 5% increase in output over the programmed value. Shorting the sense leads trips the OVP circuit.

NOTE: It is good engineering practice to twist and shield all signal wires to and from the sense connectors. Connect the shield at the dc source end only. Do not use the shield as one of the sensing conductors.

The overvoltage protection circuit senses voltage near the output terminals, not at the load. Therefore the signal sensed by the OVP circuit can be significantly higher than the actual voltage
