4 Configuring the Switch/Load Unit
Setting the UUT Power Supply Remote/Local Sense Jumpers
The UUT power supplies can be configured for either remote
sense or local sense. In local sense, the voltage across the load
equals the power supply voltage less the voltage drop across the
cables between the load and power supply. In remote sense, the
voltage across the load equals the selected power supply
voltage. In this configuration, the power supply automatically
increases the voltage output to compensate for the voltage drop
across the cables. A conceptional view of both types of sensing
is shown in Figure 4-8.
Set the power supply sense jumpers in the LOCAL position for
sensing the power supply outputs at the PB1 - PB4 terminals.
