Product Introduction
12W WiFi RF Smart Constant Current LED Driver for Indoor Lighting
Smart lighting does not always require replacing an entire luminaire. In many installations, choosing the right LED driver makes it possible to add wireless dimming and app-based control to a compatible lighting fixture.
The CENFAYA 12W WiFi RF Smart Constant Current LED Driver is designed for indoor lighting applications where convenient brightness control and reliable LED operation are important.
With Tuya APP connectivity, voice control support and optional RF 2.4G remote operation, this driver offers several ways to manage compatible LED lighting without relying solely on a conventional wall dimmer.
The series includes PB-12A-H(WT) and PB-12A-L(WT) models, making it suitable for lighting manufacturers, electrical contractors, smart home installers and commercial lighting projects.
Its single-channel constant current output, configurable current settings and flicker-free dimming design make it a practical option for compatible LED downlights, spotlights and decorative fixtures.
Design
Compact Housing for Indoor LED Lighting
The driver uses a fully enclosed protective plastic housing designed for indoor luminaire installations.
Its integrated power supply and wireless control functions help reduce the need for separate dimming equipment in suitable applications.
The driver is intended for use with compatible constant current LED modules. Before installation, the selected output current, operating voltage and available mounting space should be checked against the LED fixture's requirements.
The housing is designed for indoor environments. Installations exposed to water, condensation or excessive heat require additional consideration and appropriate equipment.
Main Features
1. WiFi Smart Lighting Control
The driver supports WiFi-based lighting control through the Tuya APP.
Users can manage supported lighting functions through a compatible smartphone and network configuration.
Available app functions include:
-
Brightness adjustment
-
Remote lighting control
-
Delayed switching
-
Timer scheduling
-
Scene editing
These features are useful in residential lighting, hospitality environments and smart lighting installations where users want more flexibility than a conventional on/off switch.
2. RF 2.4G Wireless Control
In addition to WiFi connectivity, the driver supports compatible RF 2.4G control accessories.
Optional control devices include RF remote controls and scene panels.
This provides an additional method of adjusting the lighting without using a smartphone for every operation.
The RF remote or scene panel may need to be purchased separately.
3. Voice Control Compatibility
The driver supports voice control through compatible smart home equipment, including Amazon Echo and TmallGenie.
Voice control allows users to operate supported lighting functions through voice commands after the required devices, accounts and network connections have been configured.
Availability of individual voice features depends on the connected smart home ecosystem.
4. Flicker-Free Dimming Design
The driver is designed to provide smooth, flicker-free dimming for compatible LED fixtures.
The product information lists a 4000Hz PWM frequency, which is intended to support stable brightness control.
Actual flicker performance depends on the complete lighting system, including the LED module and operating conditions.
5. DIP-Switch Configurable Constant Current Output
Unlike a standard constant voltage power supply, this driver provides a single-channel constant current output.
The output current can be configured using the integrated DIP switch according to the supported settings.
This allows the installer to match the driver to compatible LED modules, provided the selected current and output voltage fall within the manufacturer's rated operating range.
6. Universal AC Input
The driver supports an AC 100–240V input range, making it suitable for consideration in lighting projects across different electrical markets.
Local electrical regulations, product approvals and the selected luminaire's safety requirements must still be verified.
7. Built-In Protection Functions
The driver includes several electrical protection functions:
These functions help protect the driver during abnormal operation. They do not replace correct electrical design or installation.

Single-Channel Brightness Control
The driver provides one constant current output channel.
It is intended primarily for brightness adjustment of compatible single-channel LED modules.
Tunable white, RGB and RGBW operation should not be assumed without confirmation of a suitable driver configuration.
Installation
Installation Guidelines
-
Disconnect the AC power supply before beginning installation.
-
Confirm that the LED module is compatible with a 12W constant current driver.
-
Check the LED module's rated forward current and operating voltage.
-
Select the appropriate output current using the driver's DIP-switch settings.
-
Connect the AC input and LED output according to the manufacturer's wiring diagram.
-
Install the driver in a suitable indoor location with adequate thermal conditions.
-
Restore power and follow the manufacturer's instructions to pair the driver with the Tuya APP.
-
Configure supported RF accessories and voice control devices if required.
-
Test brightness adjustment, switching and smart control functions.
Important: Do not connect this constant current driver directly to ordinary 12V or 24V constant voltage LED strips unless the complete electrical system has been specifically designed for that configuration.
Electrical installation should be carried out by qualified personnel.
