Master/Slave (M/S) Operation
8.1
Series Operation
Series connection is not a permissible operating method for electronic loads and must not
be installed or operated under any circumstances!
8.2
Parallel Operation
Multiple units of same kind and model can be connected in parallel in order to create a system
with higher total current and hence higher power. This can be done using the standard models
with display and control panel or the slave 6RL models. These models are intended to run as a
slave only and thus have no TFT display.
Note: The slave models are only available as 15 kW versions, so they only match the 15 kW
standard models.
For parallel operation in master-slave mode the units are usually connected with their DC
Inputs, their Share bus and their master-slave bus, which is a digital bus that makes the system
work as one big unit regarding adjusted values, actual values and status.
The Share bus is intended to balance the units dynamically in their output voltage, i.e. in CV
mode, especially if the master unit runs a function like sine wave etc. In order for this bus to
work correctly, at least the DC minus poles of all units have to be connected, because DC minus
is the reference for the Share bus.
