The Actuator KNX S1E-BA4-UP PS with integrated façade controller regulates the 24 V DC motor for a shutter, an awning, a blind or window. The electronic output with polarity changer switches silently. An internal power supply transforms the 230 V AC mains voltage into 24 V DC to power the motor (500 mA maximum).

The automation for the drive control is specified externally or internally. Internally, there are numerous options available for blocking, locking (e.g. master-slave) and priority definitions (e.g. manual-automatic). Scenes are saved and called up via the bus (scene control with 16 scenes per drive).

The KNX S1E-BA4-UP PS has four inputs that are used as binary inputs (switches, alarm messages etc.) or as analogue inputs for T-NTC temperature sensors.
