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 specific
m voltage drop on load wires. The voltage drop is subtracted from the total voltage avai
able at the output. Follow the instructions below to configure the power supply for remote sensing:
Ensure that the AC On/Off is in the Off position.
Connect the negative sense lead to terminal J2
5 (S) and the positive sense lead to term
1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely into
the rear panel sense connector, J2.
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
If the power supply is operated without the remote sense lines or local sense jumpers, it will co
tinue to work, but the output voltage regulation will be degraded. Also, the O
vate and shut down the power supply.

J2 connector type: MC 1.5/5
Stripping length: 7mm (0.28 inches).
3.11 REPACKAGING FOR SHIPMENT
To ensure safe transportation of the instrument, contact the TDK
Lambda Americas Inc. sales or se
vice facility near you for Return Authorization and shipping information. Please att
power supply describing the problem and specifying the owner, model number and serial number of
the power supply. Refer to Wa
ranty Information for further instructions.
There is a potential shock hazard at the sense point when using a power supply
ated Output Voltage greater than 40V. Ensure that the connections at the
load end are shielded to prevent accidental contact with hazardous voltages.
n 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.
