1.9.10 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:
• PSI 9000 2U
• PSI 9000 3U
• ELR 9000
1.9.11 Sense connector (remote sensing)
In order to compensate for voltage drops along the DC cables to the load, the Sense
input can be connected to the load.
The maximum possible compensation is given in the technical specications.
1.9.12 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.
1.9.13 GPIB port (optional)
The optional GPIB connector, which is available with option 3W, will replace the
Anybus slot of standard version devices. The device then offers a three-way interface
with GPIB, USB and analog.
The connection to a PC or other GPIB port is done with standard GPIB cables from
stock, which can have straight or 90° connectors.
When using cable with 90° connectors, the USB port will be inaccessible.
