Shelly PRO DIMMER 2PM

Product Introduction

The Shelly Pro Dimmer 2PM is a professional-grade dual-channel smart dimmer designed for installation inside electrical distribution boards using a DIN-rail mounting system. It allows users to control and dim two lighting circuits independently while monitoring their energy consumption in real time.

Designed for both residential and commercial automation systems, the device supports dimmable LED lighting, halogen lamps, and compatible transformers operating on 110–240 V AC. The integrated power monitoring function measures voltage, current, and energy consumption for each channel, helping users optimise electricity usage.

With built-in Wi-Fi, LAN, and Bluetooth connectivity, the Shelly Pro Dimmer 2PM offers reliable network communication and flexible integration with modern smart home platforms. Its advanced automation capabilities make it ideal for intelligent lighting control in homes, offices, and commercial installations.
