3.2.4.4. Sense- remote voltage sensing connection
To compensate for the voltage drop over the load cables, TopCon pow-
er supplies have a “
Sense
“ connection feature.
The voltage can be measured directly at the test specimen and con-
trolled more accurately.
If this sense function is not required, the connection is simply left un-
connected.
Modifications and restrictions apply for multi-unit systems. First read
this section to become familiar with the principle. You will find a further
description on the usage of the function in multi-unit systems in the
chapter on multi-unit systems.
(See chapter 5.2.1, page 133).
Characteristics of the sense function
On the usage of the sense function the following characteristics apply to
the overall system:
The controller compensates for losses that result in particular
due to high load currents and high cable resistances.
The load cable may be interrupted in operation.
The maximum voltage compensation is adjustable.
The voltage difference between device output and sense sensor
can be monitored
TopControl: Voltage sensing - Error level.
The device will shut down if the limit is exceeded.
The circuit diagram in Fig. 19 shows the connection of the load and the
sense connections.
