Guarantee
Semiconductor switches such as thyristors or triacs also produce
interference voltages. They occur as a result of non-linear characteris-
tics and finite ignition voltages. These components must be protected
against excessive voltages, for which mainly varistors, RC combina-
tions or choke coils are used. The use of zero-voltage switches is also
recommended.
The suggestions made represent only a few of the possible ways of
protecting a microprocessor-controlled regulator system from interfer-
ence. The suggested measures have the advantage that they will
increase the lifetime of the devices, as lower induction voltages (redu-
ced spark formation) will also reduce contact burn.

Every regulator is individually tested before dispatch to ensure fully
correct functioning.
All regulators are supplied ready for connection and use.
