Two quadrants operation (2QO)

3.7.3.1 Overview
The so-called two-quadrants operation, which is based on the source-sink principle, couples a power supply and
an electronic load via a control signal. It enables the automatic switchover between either the source or the sink
being active. 2QO is also allowed for master-slave systems. A master-slave system built from electronic loads is
then considered as one big sink and will be handled and controlled as such. The same configuration is doable
with several power supplies building a big source. More information about setup, configuration and use of a 2QO
system can be found in the user manual of the master load series EL 9000 B or in the manuals of compatible power
supply series such as PSI 9000 3U.
For the operation of two master-slave system in 2QO, being connected via Share bus, the same restriction as with
master-slave operation applies: the max. number of 16 units on the Share bus.
