GLEDOPTO GL-C-211WL Synergy 21 LED Series EOS 55 WLED Controller ESP32 PWM 5in1 12/24V content_copy

The GLEDOPTO GL-C-211WL is an ESP32-based WLED controller for wireless control of analog LED light strips via WLAN. It is specifically designed for use with the WLED app and enables control of LED strips in various color modes, including single-color, CCT, RGB, RGBW, and RGBCCT light strips. The controller operates on a DC voltage of 12 to 24 V and is suitable for DIY applications where individual lighting effects are to be realized via a local network connection or optionally over the internet. An integrated night light function is also available.

Applications
The GL-C-211WL is designed for indoor use where flexible and programmable lighting is required. It is suitable for living and working spaces, showrooms, exhibitions, or technical installations where LED strips are to be controlled via a mobile app. The support for various color modes enables a wide range of application scenarios, from decorative lighting to functional room illumination. The maximum total load of 15 A (equivalent to 360 W at 24 V) makes it suitable for larger LED installations that supply multiple strips simultaneously.

Features and Specifications in Detail
The controller features a PWM mode, enabling precise control of the brightness and color temperature of LED strips. The maximum output power is 15 A in total, with each channel capable of delivering up to 10 A. This is sufficient to operate multiple LED strips in parallel, provided the total power consumption is not exceeded. Control is performed via the WLED app, which can be installed on smartphones or tablets. The app allows setting colors, brightness, lighting effects, and schedules. The night light function can be activated via the app to ensure a constantly available, low-level brightness.

Technology Explained Simply
The controller is based on an ESP32 chip, responsible for wireless communication via WLAN. This chip enables connection to the local network, allowing control via the WLED app. The PWM control (pulse width modulation) regulates the brightness of the LEDs by varying the pulse width, enabling flicker-free and precise brightness control. The input voltage of 12 to 24 V DC is standard for LED strips and thus compatible with most common power supplies. The operating temperature range of -20 to +45 °C indicates that the controller functions reliably even under cooler conditions.

Compatibility and Accessories
The GL-C-211WL is compatible with analog LED light strips of types single-color, CCT, RGB, RGBW, and RGBCCT. Control is performed via the WLED app, connected through the WLAN network. No specific accessories are included in the delivery; network connection is made via an existing WLAN router. The app is available separately and must be installed on the end device. No additional adapters or connectors are required, as the controller connects directly to the LED strips.

Installation and Mounting
The controller connects directly to the LED strips, with power supply provided by an external power source delivering 12–24 V DC. Mounting is typically done at a stable, dry location indoors, as the protection rating IP20 does not offer protection against moisture or dust. The dimensions of 108 × 45 × 18 mm allow for compact placement, for example in an electrical installation or on a wall. Installation does not require special tools, but secure connections for power supply and LED strips are necessary.

Operational Advantages
Operation of the GL-C-211WL is simple and flexible. Control via the WLED app enables intuitive use, even for users without technical background. The ability to individually program lighting effects, colors, and brightness levels offers high adaptability. The night light function adds extra safety and comfort. The use of PWM control ensures flicker-free and even lighting. The maximum total power of 15 A allows control of larger LED installations, with attention required to load distribution across individual channels.

Note on Protection Rating
The protection rating IP20 means the controller is protected against contact with fingers and against solid objects larger than 12.5 mm, but not against dust or water. Therefore, it is suitable exclusively for indoor use. For outdoor use or in damp rooms, a controller with appropriate protection is required.

Package Contents
The package includes only the controller itself. No additional components such as power supply, cables, or mounting materials are included. The WLED app must be downloaded and installed separately.
