Description
The WMU 831/851/852 actuators are medium-chain actuators specially designed for large and heavy windows—complete opening of the window within 60 seconds. The TrueSpeed™ feature enables an opening of 1 mm per second, can control several motor lines simultaneously and ensures a higher degree of control.
Features and benefits:
- To be used together with ±24 V control units or control units with MotorLink®.
- Can be used together with espagnolette WMB.
- Available with and without cable: S = cable/ Z = no cable.
- External safety edge can be connected directly to the actuator.
- Synchronization of up to four window actuators – no need for an external synchronization module.
- Genuine position feedback and three speeds when using control unit with MotorLink®.
- Soft close function.
- Built-in electronic load switch-off/end stop.
- Electronic actuator with microcontroller.
- The actuator has an integrated reverse function to ensure a prolonged life span of the window gaskets.
- Easy mounting.
