Heavy lift 24 Volt DC linear actuator with a stroke of 750mm. and a push / pull force of  max.1800N. with Tandem function.
Widely applicable on heavy windows, skylights and roof windows for daily ventilation or SHEV systems. (acc. EN 12101/2).

The tandem function allows to connect up to 4 actuators in parallel.
If one actuator is stopped due to overload, the other connected actuators will stop automatically to prevent damage.

Standard equipped with:

  • “F” contact for sequence controlling
  • Operation of the electric actuator for the OPEN and CLOSE driving directions.
  • Tandem function enables the coupling of further actuators. (max. 4)
  • Current-controlled cut-off.
  • Multiple triggering lock function in the end positions and in case of overload.
  • Soft start of the electric actuator.
  • Undervoltage protection of the actuator.
  • Cycle counter for actuations and cut-offs.
  • Speed detection.
  • Stroke programming function.
  • “F” contact for sequence controlling
  • Maximum rated current can be set in ‘OPEN/CLOSE’ driving directions by rotary switch.
  • Possibility to connect parameterising interface.

Optional: Possibility to connect end switch.

Aluminum housing, anodized EV1/E6

Supplied without mounting brackets. These must be ordered separately.
Because of the high forces, you have to use the strengthened brackets. (See "related products" tab)
