Sunricher DIN rail Zigbee smart dimmer, 230V AC no neutral, 400W (SR-ZG9042A-D)

The Sunricher SR-ZG9042A-D is a DIN rail-mounted Zigbee smart phase-cut dimmer based on the Zigbee 3.0 protocol. Thanks to its wide input and output voltage range (100–240 VAC), it is compatible with a variety of lighting loads up to 400 W. It supports resistive, capacitive, and inductive loads and is available in both leading-edge and trailing-edge dimming types, preconfigured at the factory.

The SR-ZG9042A-D is ideal for integration in residential or industrial environments. It’s a great choice for more advanced DIY users, as it can be controlled via both TouchLink and Zigbee network, offering flexible configuration options such as minimum and startup brightness levels.

The device supports energy monitoring, push-button control, and intelligent restart from minimum brightness. While not a Plug&Play product, it delivers stable and reliable performance after installation – making it particularly suitable for advanced users and professional system integrators.
