2.5.2 Remote Sensing Connections
There are two sensing points in the Electronic Load module. One is measurement at Load,
terminal, and another is measurement at Vsense. The Load module will automatically
switch to Vsense when Vsense terminals are connected to UUT, otherwise it will measure at
Load terminals. Remote sensing compensates for voltage drop in applications that require
long lead lengths. It is useful when a module is operating in CV or CR mode, or when it
needs precise measurement. Figure 2-5 also illustrates a typical setup for remote sensing
operation.
L NOTICE
The potential of Vsense red connector must be higher than that of Vsense black connector.
2.5.3 Parallel Connections
Figure 2-6 illustrates how modules can be paralleled to increase power dissipation. Modules
can be directly paralleled in CC, CR modes for static operation, but cannot be paralleled in
CV mode. Each module will dissipate the power it has been programmed. For example, if
two modules are connected in parallel, one is programmed 10A, and another is 15A, the total
current drawn from the source is 25A.
