    Installation Sensing Function There are two types of sensing: local sensing and remote sensing. By factory default, the product is set to local sensing (the SENSE switch is set to off). Local sensing Use local sensing when the cable to the load is short. Local sensing does not compensate for the voltage drop in the load cable, so use this method when the load current is small or when you do not need to consider the load regulation voltage.
