5WG1420-3AB11 Product Description Siemens 5WG1420-3AB11, also named KNX dimmer actuator, is a lighting control module for KNX EIB building automation system. It is designed to adjust output voltage for dimming lamps, supporting intelligent light brightness regulation for old building control equipment renovation.

This actuator delivers reliable light dimming for building control tasks. The light dimming supports continuous brightness adjustment for compatible lighting loads. The light dimming realizes scene recall and brightness preset function. Stable light dimming completes automatic lighting management for building spaces.

The built-in power circuit achieves steady load driving. The load driving outputs adjustable AC voltage to connected lamps. The load driving supports over-current and over-temperature protection. Accurate load driving ensures lighting status follows KNX bus commands.

DIN rail mounting structure brings convenient cabinet installation. Cabinet installation can be directly clipped on control cabinet DIN rail. Cabinet installation connects KNX bus and lighting loads via screw terminal block. Flexible cabinet installation is widely used for legacy KNX system spare replacement.

5WG1420-3AB11 supports load fault detection and status feedback function, equipped with screw terminals for bus and power wiring. It has LED status indicators for operating state and fault diagnosis. Widely applied in office buildings, shopping malls and intelligent building control systems. This product is discontinued by Siemens, mainly supplied as industrial spare parts, complying with KNX building automation standards.
