Triac / Phase-Cut Dimmable LED Driver：

 Triac or phase-cut dimmable LED drivers allow for brightness control of LED lighting using standard wall dimmers. They function by “cutting” the AC                    voltage waveform to reduce the power delivered to the LED load.

Welllux Triac / phase-cut dimmable drivers are compatible with mainstream brand dimmers and lighting systems, including leading edge & trailing edge (  forward phase, reverse phase, ELV, Triac, or MLV ), with brands including Lutron, Clipsal, C-BUS, Leviton dimmer, and other lighting systems.

* Key Specifications & Types

Constant Voltage (CV): Typically used for LED strips and cabinet lighting. Common outputs include 12V and 24V DC.

Examples: 24W/12V drivers, 60W/24V options, and high-power 200W/24V units.

Constant Current (CC): Used for individual high-power LEDs & downlights. Maintain a steady current (e.g., 350mA, 500mA, 700mA)  while the voltage varies.

Examples: 10W—60W drivers with selectable current via DIP switches. ( selectable via DIP switches from 100mA to 1050mA and 3CCT color adjustable)

Dimming Compatibility: Support both leading-edge (Triac) and trailing-edge (ELV/reverse phase) dimming.

Protection: High-quality drivers include built-in protections for short circuits, overloads, over-voltage, and over-temperature.

* Performance

Dimming Range: Quality drivers can achieve a smooth dimming range from 1 to 100%.

Flicker Control: Without flickering or buzzing if you are looking for “flicker-free” rated drivers to ensure stability.

Installation: These drivers are ideal for retrofits because they use existing AC wiring and do not require additional control wires like 0–10V or DALI systems.

0/1—10V Dimmable LED Driver：

0/1—10V dimmable LED drivers use a low-voltage DC signal (0V to 10V) to control light intensity, a method widely used in commercial and industrial lighting systems. Unlike TRIAC dimming, these drivers require a dedicated pair of control wires (typically purple and gray/pink) to transmit the dimming signal from the controller to the driver.

* Common Specifications

Drivers are available in two primary output modes to match different LED types:

Constant Voltage (CV): Used for LED strips and linear lighting. Standard outputs include 12V and 24V with power ratings from 30W to over 300W.

Constant Current (CC): Used for downlights, spotlights, linear light, surfaced or recessed of indoor or outdoor luminaires. Many models can add DIP switches to select currents (e.g., 100mA, 130 mA, 150 mA, 200mA, 300mA, 350mA, 500mA, 700mA, or 1050mA) to support various fixtures.

Multi-Protocol Support: Higher-end “5-in-1” models support multiple dimming methods, including 0-10V, 1—10V, TRIAC, PWM, and Potentiometer signals.

* Key Performance Features

Flicker-Free Technology: Professional-grade drivers with stable, flicker-free dimming down to even 0.1% smooth dimming effect. Including Tunable white means adjustment of brightness and colour temperature together, Double channel constant voltage output, High input voltage of 120VAC ~ 277VAC, Over load protection, short circuit protection, thermal management, suitable for indoor and outdoor LED lighting projects.

System Capacity: A single 0–10V dimmer can often control dozens or hundreds of drivers simultaneously, far exceeding the capacity of standard residential phase-cut dimmers.

DALI & Push Dim (2 in 1) Dimmable LED Driver：

A DALI & Push Dim (2-in-1) LED driver is a versatile power supply that supports two distinct digital dimming protocols in a single unit. This allows installers to use the same driver for either advanced DALI-2 building automation or a simple, cost-effective Push Dim (also known as Switch-Dim or Touch-DIM) manual control system.

* Core Functionality

DALI-2 Mode: Uses the standard DALI protocol (IEC 62386) for bidirectional communication, allowing individual addressing, group control, and status feedback within a smart building network.

Push Dim Mode: Allows dimming via a standard, normally-open (momentary) wall switch.

Short Press: Turns the light ON/OFF.

Long Press: Adjusts the brightness level up or down.

Memory Function: Most drivers remember the last dimming level even after power loss.

* Key Specifications & Features

Output Types: Available in Constant Voltage (CV) for LED strips (12V, 24V, 48V) and Constant Current (CC) for ceiling surface lamp, spotlight and downlights (often selectable via DIP switches from 100mA to 1050mA).

Dimming Range: High-quality drivers offer smooth, flicker-free dimming from 100% down to 0.1%.

Advanced Configuration: Many models feature NFC technology, allowing users to adjust output voltage or set DALI addresses wirelessly using a smartphone app before installation.

Protection: Standard built-in safeguards include short-circuit, over-load, over-voltage, and over-temperature protection.

DALI Mode: Large-scale commercial offices, hospitals, and luxury smart homes requiring centralized software control.

Push Dim Mode: Residential retrofits or small offices where a simple manual dimming solution is needed without extra control hubs.

 3CCT Color Adjustable LED Driver：

Tri 3CCT Switchable driver has two DIP types (with DIP switch on the driver or with DIP switch on a separate wire) and Power DIP adjustable driver is an “all-in-one” power supply that allows for manual field adjustment of both light color and power wattage of brightness. These drivers typically feature two separate banks of DIP (Dual In-line Package) switches on the housing or with a separate DIP switch.

* Dual Adjustment Functionality

3CCT DIP Switch: Allows selection between three pre-set Correlated Color Temperatures (CCT).

Warm White (2700–3000K): Ideal for residential and hospitality settings.

Neutral/Cool White (4000–4500K): Standard for offices and workspaces.

Daylight (6000–6500K): Used for task lighting, warehouses, and outdoor floodlighting.

Power Selectable DIP Switch: Adjusts the output wattage or current, effectively changing the maximum light brightness of the LED fixture.

Example: A single driver might be toggleable between 9W, 12W, or 18W, 3000K, 4000K, 6500K depending on the specific lighting requirements of the space.

Emergency Retrofit Pack:

Transform any LED light fixture into a reliable source of emergency lighting with our standard 3-Hour Emergency Retrofit Pack. Compatible with LED fittings ranging from 3 to 50 watts that operate with both on/off or smart dimming drivers, this retrofit solution ensures that the lighting remains functional even during a power cut.

Easy Installation: Connect the switched and unswitched live supply directly to the retrofit pack. During normal operation, control your lights with the usual on/off switch. In the event of a power interruption, the retrofit pack automatically switches to battery power (supplied complete with a Li-ion battery), maintaining illumination without interruption.

Smart Power Management: Equipped with an intelligent monitoring system, the retrofit pack adjusts the output current to the LED, optimising the match between the battery capacity and the LED load. This not only maximises efficiency but also ensures maximum brightness for three hours during emergencies.

Seamless Integration: Available in standard or with junction box designs, the retrofit pack can be discreetly installed, maintaining the aesthetic of your space while adding crucial functionality. It works seamlessly with your existing LED driver, making it a versatile and essential addition to any lighting system.
