Maintronic CRD300 Casambi 300VA Wireless Universal LED Retrofit Dimmer

Maintronic CRD300 Casambi 300VA Retrofit Universal Dimmer

The Maintronic CRD300 is a Casambi enabled retrofit universal dimmer designed to provide wireless control of compatible LED and conventional lighting loads. With a maximum rated load of 300VA, it combines intelligent dimming technology with flexible control through the Casambi app or a connected push button.

Suitable for smart lighting installations in residential, commercial and hospitality environments, the CRD300 automatically detects the connected load and adjusts its dimming characteristics to help achieve smooth, stable lighting performance.

Wireless Casambi Lighting Control

The CRD300 integrates into a Casambi wireless lighting network, allowing users to control and configure compatible lighting through the Casambi app on a smartphone or tablet. It can be incorporated into lighting groups and scenes, helping simplify the management of connected lighting installations.

An additional push button input enables local control, providing an alternative to app based operation. Push button behaviour can be configured to suit the installation.

Intelligent Adaptive Dimming

The CRD300 features digital leading edge and trailing edge phase dimming with automatic load detection and AdaptiveDIM technology. During initial commissioning, the dimmer measures the connected load and calculates suitable dimming characteristics, helping establish stable minimum and maximum brightness levels.

It supports compatible resistive, inductive and capacitive loads, including suitable retrofit LED lamps. Additional features include soft switching, adjustable fade times and a load number indicator.
