PWM three-channel low voltage controller - long range rH-PWM3-LR RH-PWM3-LR

Lighting and low-voltage device control with F&Home Radio

The rH-PWM3 PWM controller is an element of the F&Home Radio smart home system, designed for precise control of three low-voltage receivers. The device allows you to adjust the power through pulse width modulation (PWM), which provides full control over the brightness of LEDs, the speed of DC motors, or the activation/deactivation of electromagnetic locks. The PWM pulse frequency is adjustable in the range of 100 Hz to 1 kHz, allowing you to adapt the device's operation to the specifics of the controlled load. Communication with the central unit is wireless, in the 868 MHz band, ensuring a stable connection and a range of up to 100 meters in open space.

Why choose rH-PWM3?

• Versatility: Ideal for controlling LEDs (including RGB), electromagnetic locks, DC motors and other low-voltage devices.
• Precision: PWM modulation enables smooth power adjustment and adaptation of the operating parameters of controlled devices.
• Wireless communication: Facilitates installation and eliminates the need to run additional cables. The radio range of up to 100m ensures comfortable use even in large facilities.
• Two-way transmission: Provides reliable confirmation of command execution and device status monitoring.
• Compact dimensions: The flush-mount module with dimensions of 48 x 48 x 22 mm makes it easy to install in standard recessed boxes.
• Protections: Built-in overheating and overvoltage protection protects both the controller and connected devices.

Technical specifications and application

The rH-PWM3 controller has been designed with ease of integration with the F&Home Radio system in mind. Thanks to two-way radio communication (868 MHz) and the ability to adjust the PWM frequency (100-1000 Hz), it provides flexible and precise control of various low-voltage loads. The output load is 3 x 4A / 12V DC, allowing you to control multiple devices simultaneously or one with higher current consumption. In addition, built-in overheating and overvoltage protection increases safety and protects connected devices from damage.

The device finds application both in home installations (controlling LED lighting, RGB tapes) and commercial installations (alarm systems, access control). Thanks to the possibility of remote control via a mobile application or central panel, the user has full control over the system from anywhere. Mounting in a recessed box ensures an aesthetic appearance of the installation and easy access to the device in case of service or configuration. The IP20 protection class means that the device is intended for use in dry indoor rooms.
