4.9 Proportional Control Unit – PCU (Optional)
The actuators can be equipped with an additional PCU-PCB (Printed Circuit Board). This circuit board
includes a mounting kit and can be installed in any standard open-close actuator. The PCU converts an
open-close actuator into a modulating actuator.
4.9.1 PCU-EB – Proportional Control Unit Alternating Current (NEW VERSION)
Note: Please be aware that in the year 2020 a new version of this PCU was introduced. Please check which
PCU is mounted or is going to be mounted in your actuator. The old version is marked with PCU-A and
the new version is marked with “PCU-EB”. Both have their own manual. See paragraph 4.9.2 for the
PCU-A manual.
