Sunricher Zigbee retrofit smart dimmer, 230V AC no neutral, 250W (SR-ZG9041A-D)

The Sunricher SR-ZG9041A-D is an ultra-compact, Zigbee 3.0-based phase-cut (Triac) LED dimmer, specifically designed for modern smart home systems. The device operates on a single live wire – no neutral wire or additional cabling required – making it an excellent solution for retrofitting older buildings or installations with design constraints. It also supports power consumption monitoring, making it useful not only for dimming but also for energy tracking.

This miniature dimmer is highly versatile: thanks to its 100–240 V AC input and output, it can handle up to 200 W (at 220 V) or 100 W (at 110 V) loads. It supports both leading-edge and trailing-edge dimming technologies, which can be pre-configured at the factory. An innovative minimum brightness setting function allows users to define a minimum brightness level and dim up to 100% from there. This setting can be cleared anytime with ease.
