3.10.3 Remote sensing

WARNING

There is a potential shock hazard at the sense point when using a power supply with a rated Output Voltage greater than 40V. Ensure that the connections at the load end are shielded to prevent accidental contact with hazardous voltages.

CAUTION

When using shielded sense wires, ground the shield in one place only. The location can be the power supply chassis or one of the output terminals.

Use remote sense where the load regulation at the load end is critical. In remote sense, the power supply will compensate for voltage drop on the load wires. Refer to the power supply specifications for the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage avail- able at the output. Follow the instructions below to configure the power supply for remote sensing:

1.Ensure that the AC On/Off is in the Off position.

2.Remove the local sense jumpers from J2.

3.Connect the negative sense lead to terminal J2-5 (-S) and the positive sense lead to terminal J2- 1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely into the rear panel sense connector, J2.

4.Turn On the power supply.

Notes:

1.If the power supply is operating in remote sense and either the positive or negative load wire is not connected, an internal protection circuit will activate and shut down the power supply. To resume operation, turn the AC On/Off to the Off position, connect the open load wire, and turn On the power supply.

2.If the power supply is operated without the remote sense lines or local sense jumpers, it will con- tinue to work, but the output voltage regulation will be degraded. Also, the OVP circuit may acti- vate and shut down the power supply.
