Fig. 3-1: Single load connection, Local Sensing
The wires should be properly terminated with terminals securely attached. DO NOT use non
terminated wires for load connection at the power supply.
Fig. 3-1 illustrates the connection of a single load to the power supply using local sensing. This
connection is made via the “External Control Connector” located on the rear panel of the power supply.
Local sensing is suitable for applications where load regulation is not critical.
