TDK Lambda | Z+Low Voltage User Manual

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 ismade at the output terminals. Thismethod 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.

3.10.3 Remote Sensing

WARNING: There is a potential shock hazard at the sense point when using power supplywith 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 loadwithout 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.
