Four-wire sense connection
Using four-wire remote sensing connections ensures that the programmed voltage is applied to the
load and compensates for the voltage drop in the leads between the power supply and the load. The
maximum voltage drop is 1 V per lead.
As shipped, the sense terminals are connected to the output terminals by shorting jumpers. Before
connecting the wire, make sure the shorting jumpers have been removed. When you connect the
power supply for remote sensing, the overvoltage protection (OVP) circuit senses the voltage at the
sensing points (load) and not the output terminals.
