1.9.10 “Share” connector

The 2 pole socket (“Share”) on the back side of the device is provided for connection

to equally named sockets on compatible electronic loads when establishing parallel

connection where symmetric current distribution is required, as well as compatible

power supplies to build a two-quadrants operation setup. For details about this feature

operation (2QO)“. Following power supply and electronic load series are compatible:
•

PSI 9000 2U/3U (new from 2014)

•

ELR 9000

1.9.11 “Sense” connector (remote sensing)

In order to compensate for voltage drops along the DC cables from the source, the

Sense input can be connected to the source.
The maximum possible compensation is given in the technical data.

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 devices of the same model to be connected via a digital bus (RS485) to create a

master-slave system. Connection is made using standard CAT5 cables. It 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.
