Remote Sensing 3.10.3
Use remote sense where the load regulation at the load end is critical. In remote sense, the power supply will
compensate for voltage drop across the load wires. Refer to the power supply specifications for the maximum
voltage drop across the load wires. The voltage drop is subtracted from the total voltage available at the output.
Follow the instructions below to configure the power supply for remote sensing:
1. Ensure that the Power Supply AC ON/OFF switch is in the OFF position.
2. Remove the local sense jumpers from the J2 mating connector.
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
J2 sense connector.
4. Press the Power Supply AC ON/OFF switch to the ON position.
Notes:
1. If the power supply is operating using 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, press the AC ON/OFF switch to the OFF position, connect the open load wire, and then turn
On the power supply.
2. If the power supply is operated without the remote sense lines or local sense 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.

3.11 REPACKAGING FOR SHIPMENT
To ensure safe transportation of the instrument, contact the TDK Lambda Americas Inc Sales or Service facility
near you for Return Authorization and shipping information. Please attach a tag to the power supply describing
the problem and specifying the owner, model number and serial number of the power supply. Refer to Warranty
Information for further instructions.
WARNING
There is a potential shock hazard at the J2 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.
