For ...H1
When DIP switch S1.5 is at „ON“, the maximum load voltage (with
U/U
2 control) can be defined on potentiometer R201 TRAFO ADAPTI-
ON. The control characteristic curve is adapted in accordance with the
following equation: U
load max
= (No. of turns R201 : 9) * U
type
4.3.4 Setting maximum load current (only for...H RL1 and ...H RLP1)
The maximum load current is limited with potentiometer R203
CURRENT LIMIT, irrespective of the control mode. If there is no
I control, the potentiometer works as current limiter.
At reduced ambient temperatures, the power controller can only be
operated with up to 110% of its nominal current (effective value) (see
page 82, Technical Data).
