Product Details
The actuator is a high-performance, medium chain actuator specially designed for large and heavy windows – an elegant alternative to spindle actuators.
Complete opening of the window within 60sec.
Description
– to be used together with ±24V control units or control units with MotorLink®
– can be used with espagnolette WMB
– synchronization of up to 4 window actuators - no need for an external synchronization module
– genuine position feedback and 3 speeds when using control unit with MotorLink®
– soft close function
– the electronics in these actuators can be programmed to suit specific requirements – i.e. pressure- and traction force, stroke, speed/sound level with the WAT 100 programming box, this is also possible following installation
– built-in electronic load switch-off/end stop
– electronic actuator with micro controller
– the actuator has an integrated reverse function to ensure a prolonged life span of the window gaskets
– easy mounting
– New processor designed
– The TrueSpeed™ feature enables an opening of 1 mm per second, can control several motor lines simultaneously and ensure higher degree of control
– New five-pole plug solution for easy installation
– Ability to connect pressure safety strips
