3.10.3 Remote Sensing
WARNING:
There is a potential shock hazard at the sense point when using power supply with an output voltage
greater than 60VDC. Ensure that the connections at the load end are shielded to prevent accidental
contact with hazardous voltages.
WARNING:
Do not operate the Power Supply with remote sense wire connected to the load without connecting
load wire to the output terminal. Make sure that the connection is reliable to avoid disconnection
during operation. Disconection may cause damage to the power supply.
3.10.2 Local Sensing
The power supply is shipped with the rear panel J2 sense connector wired for local sensing of
the output voltage. Refer to Table 3-4 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.
Terminal Function
J2-1 Local negative sense. Connected internally to the negative output terminal (-LS).
J2-2 Remote negative sense (-S).
J2-3 Remote positive sense (+S).
J2-4 Local positive sense. Connected internally to the positive output terminal (+LS).
