2.
Option IL (Isolating lacquer)
To protect the electronic components of the power feedback unit from
pollution of the cooling air, all printed circuit boards may be coated with an isolating
lacquer. This option improves the service reliability, but it doesn’t release the user from
the duty to observe the in chapter 3.2 specified application conditions.
3.
Option SKS-module
For all power feedback units a SKS-module is available. This module enables the power
feedback unit to generate sine wave mains currents (THD I =8-15% depending on con-
troller and load). In addition the maximum feedback power increases by approx. 15% in
relation to operation without SKS-module. The module has to be connected to the
power feedback unit according to figure 4.4.1.1.1. For technical data refer to chapter
3.3.4 (type overview) and 4.2.3 (dimensions).
4.
Overvoltage-suppressor
If the power feedback unit (as well as a controller) is connected to ungrounded mains
supply, it only may be run, either if it is connected via an isolating transformer or if the
plant is protected by overvoltage suppressors. But also with grounded mains supply it
may be useful to install overvoltage suppressors, if it is possible, that voltage peaks oc-
cur. For choosing the best overvoltage suppressor for your specific application, please
get in contact with one of our technicians.
