Remote Sensing Connections; Parallel Connections - Chroma 63200 Series Operation & Programming Manual

2.4.2

Remote Sensing Connections

There are two sensing points for the Electronic Load.
terminal, and another is measurement at Vsense. The Load 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 the load is operating in CV or CR mode, or when it needs
precise measurement. Figure 2-2 also illustrates a typical setup for remote sensing
operation.
Notice
The potential of V-sense red connector must be higher than that of V-sense black connector.
2.4.3

Parallel Connections

63200 series Loads can be paralleled to increase power dissipation. The Loads can be
directly paralleled in CC mode for static or dynamic operation while in CR and CP modes the
Loads can be paralleled for static operation only. It is not suggested to parallel Loads in CV
mode.
The Loads is linked via RS-485 cable to RS485 port. RS485 address represents the ID of
each Load in the parallel group.
There are two operation modes in this parallel function:
The first is MASTER mode. The master gets the total setting commands from the remote
control or front panel and then informs the slaves what setting current they should do
according to their model. (The slave model has to be ready first.) So the only one you need to
program is the master.
The second is MASTER SYNC mode. Each Load gets the current setting from its own remote
control or front panel, the master controls the loads H/W synchronization action so that all
loads can be operated with same action at the same time no matter in static or dynamic mode.
Referred to Section 4.2.9 for detail information of setting the Loads parallel function
parameters.
