Bidirectional Protocol Gateway
Seamlessly bridges KNX and RF433MHz systems with two-way protocol conversion, acting as a core hub between wired and wireless ecosystems.
Bus-Powered Operation
Draws power directly from the KNX TP1 bus, eliminating the need for separate power supplies and enabling clean, integrated installation.
Plug-and-Play Integration：As a standard communication expansion module, it allows for quick and straightforward integration of wireless subsystems into any KNX project, streamlining design, deployment, and retrofit processes.
Our ERC2303 wireless dimmer receiver can be paired with Ebelong wireless kinetic switch, which is wireless and battery-free.
One very small size product, can be hidden in the corner of furniture.
A wireless dimmer supporting PWM dimming. You can use an ERC2303 controller adjust the color temperature of light strip.
APP & voice control supported, a wonderful part of your smart home automation.
ERC2303 wireless dimmer receiver is a small low voltage DC PWM dimmer receiver, especially suitable for furniture lighting strip control.
Using an ERC2303 wireless dimmer receiver, upgrade your traditional wired devices to intelligent system.
