24 Volt DC Chain actuator with tandem fuction. Maximum push/pull force of 300N.
Suitable on windows and vents in (N-)SHEV installations and for daily ventilation purposes. Because of the compact extruded aluminium housing (35x37mm.) very widely applicable.

Silent and powerful chain actuator with "Soft-close" and "Soft-start" function. Also equipped with "F-contact" for feedback signal or a "Volt-free contact" (depending on how the actuator is connected).

To ensure a good sealing this actuator has an electronic "zero-reset" in the last 30mm. of the closing stroke.This means that everytime the vent/window is closed, the actuator will automatically reset the exact "closed-position" by the built-in electronic overload cut-off.

Different functions, like stroke length, push/pull force, softclose function etc. can be fine-tuned with the SimonLink® software. (We can set this up for you before delivery or on site)

The bracket for connecting the chain to the frame or sash profile AND the mounting brackets for the housing are sold separately. (Exact model depending on mounting method). The different brackets can be found below under "Related Products".

This actuator is also available with a "DA" option. With this option you get the same actuator, but with an extra cable connection that makes it possible to connect a second EA-K-30 in parallel.
