PSB 9000 3U Series
1.9.10 “Share” connector
The 2 pole WAGO socket named “Share” on the back side of the device is provided
for connection to equally named sockets on compatible devices of different type and
is used to achieve a balanced load current distribution while running the units in par-
allel connection. Following power supply and electronic load series are compatible:
•
PSB 9000 3U
•
PSI 9000 2U - 24U / PSI 9000 3U Slave / PSI 9000 WR 3U / PSI 9000 WR 3U Slave
•
ELR 9000
•
EL 9000 B / EL 9000 B HP / EL 9000 B 2Q
•
PSE 9000
•
PS 9000 1U / 2U / 3U *
* Only from hardware revision 2, see type label (in case it does not show “Revision” on type label, it is revision 1)
1.9.11 “Sense” connector (remote sensing)
In order to compensate for voltage drops along the DC cables to the load or external
source, the Sense input can be connected to the load resp. external source. The
maximum possible compensation is given in the technical specifications.
In order to ensure safety and to comply to international directives, insulation of high voltage
models, i. e. such with a nominal voltage of 500 V or higher, is ensured by using only the two
outer pins of the 4-pole terminal. The inner two pins, marked with NC, must remain unconnected.
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
module 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.
