2.9 Local And Remote Sensing

The rear panel J2 sense connector is used to conﬁgure the power supply for local or remote

sensing of the output voltage. Refer to Fig.2-6 for sense connector location.

There is a potential shock hazard at the sense connector when using a power

supply with a rated output voltage greater than 40V. Local sense and remote

sense wires should have a minimum insulation rating equivalent or greater than

the maximum output voltage of the power supply. Ensure that the connections at

the load end are shielded to prevent accidental contact with hazardous voltages.

The power supply is shipped with the rear panel J2 sense connector wired for local sensing

of the output voltage. See Table 2-4 for J2 terminals assignment. 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.
