Chain Drive KS2 S2 230V AC R/L

Reliability in the smallest space

Due to a force of 250N and a compact drive size – which allows a profile integrated mounting – KS2 chain actuators are optimally suited for reliable opening and closing of windows.

Product Details

  • Electronic speed regulation for synchronous motor running and low noise development
  • Housing of natural, anodised aluminum, RAL9016 or upon request in other RAL colours
  • Suitable for surface mounted drives and concealed fitting within profiles
  • Rigid drive mounting on frame without brackets
  • Universal brackets and casement brackets for all common profile systems
  • Side bow roller chain of high-quality stainless steel for large opening angles with the smallest possible bending radii
  • The chain completely retracts into the housing to ease profile integrated mounting of the drives
  • Z-version:  programmable feedback limit position “OPEN” or “CLOSE”
  • TWIN-version with 2 chains and double force
  • Programmable parameters of intelligent S12 electronic cut-off switch:


      • Synchronised multi-operation of up to 4 opening and 2 locking drives with sequence control
