N 543D31 KNX Solar Protection Actuator 4xAC 230V 6A with End Position Detection 5WG1543-1DB31
The N 543D31 KNX solar protection actuator provides four-channel control of AC 230 V sunblind, shutter, and awning drives in intelligent building systems. Each channel is rated for 6 A and features end position detection to verify upper and lower travel limits.
Bus-powered electronics eliminate auxiliary supply wiring, and automatic travel time determination simplifies commissioning. The device transmits status objects cyclically or on request, covering position, slat angle, override, and travel direction. Integrated functions include scene control, wind and rain alarm response, forced position, frost protection, and configurable startup after bus voltage recovery.
