If the power supply is operated without the remote sense lines or local sense

NOTE

 

jumpers, it will continue to work, but the output voltage regulation will be

 

degraded. Also, the OVP circuit may activate and shut down the power supply.

 

 

 

Local Sensing

The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the output voltage. With local sensing, the output voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore it is recommended only for low load current applications or where the load regulation is less critical.

Remote Sensing

Use remote sensing in applications where load regulation at the load is critical. Remote sensing allows the power supply to automatically compensate for the voltage drop in the load leads. Refer to Appendix A for the maximum allowable voltage drop on the load wires.

Remote sensing is especially useful in constant voltage mode with load impedances that vary or have significant lead resistance. It has no effect in constant current mode. Because sensing is independent of other power supply functions it can be used regardless of how the power supply is programmed. With remote sensing, voltage readback monitors the load voltage at the remote sense points.

Use twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either at the power supply chassis or the load ground. The optimal point for the shield ground should be determined by experimentation
