5. Multi-unit system
5.1.
Introduction
Due to the fully digital control of the TopCon power supplies, all control
signals are exchanged between the devices without losses within a mul-
ti-unit system.
Master/slave system
A multi-unit system can only be made up of TopCon power supplies of
the same type (model number).
The devices can be connected together in the following operating
modes:
Serial
To increase the output voltage,
the outputs of all devices are connected
in series
.
Parallel
To increase the output current,
the outputs of all devices are connected
in parallel
.
Matrix
Some of the systems are connected as a serial multi-unit system,
at least two of these serial configurations are connected in paral-
lel.
Multiple load
Each device supplies
a load
and is not connected with any other
device or only to one connection terminal on another device.
In principle the operating modes act on two areas:
Load connections
The outputs on the TopCon power supplies are connected ac-
cordingly in the
serial, parallel, multiple load or in the matrix multi-unit system.
The related total output value is distributed evenly over all Top-
Con power supplies in the multi-unit system.
Internal communication
All devices in the multi-unit system are taken into account during
internal system communication by means of device addressing.
Along with the TopCon power supplies this aspect also covers
the HMI and RCU.
System communication
The system communication in multi-unit systems is ensured by the digi-
tal exchange of data (CAN). The wiring is undertaken with individual
point-point connections between the devices (modules) as well using
the terminating resistors at the two physical ends of the bus structure.
