1.10.10 Share Bus-Connection
The 2 pole WAGO socket (“Share”) on the back side of the device is provided for
connection to equally named sockets on compatible power supplies series to achieve
a balanced load current distribution during parallel connection. The socket is also
used to connect the power supply to compatible electronic loads, in order to build a
two-quadrants operation setup. Following power supply and electronic load series
are compatible:
•
PS 9000 2U/3U
•
PSI 9000 2U/3U
•
ELR 9000
1.10.11 Sense connector (remote sensing)
If the output voltage has to be dependant on the consumer location rather than the DC
output of the power supply, then the input “Sense” can be connected to the consumer
where the DC connection is made. This compensates, up to a certain limit, the volt-
age difference between the power supply output and the consumer, which is caused
by the high current through the load cables. The maximum possible compensation
is given in the technical data.
1.10.12 Master-Slave bus
A further port is provided on the back side of the device, comprising two RJ45 sockets,
which enables multiple identical devices to be connected via a digital bus (RS485)
to create a master-slave system. Connection is made using standard CAT5 cables.
These can theoretically have a length of up to 1200 m, but it is recommended to keep
the connections as short as possible.
