Control & Drivers

LED drivers and lighting controls are the devices that power LED modules and let you dim, switch and schedule them, from simple phase-cut dimmable drivers to networked DALI-2 and Bluetooth systems. This Kosnic range includes 20W to 40W DALI-2 drivers with 1-10V and push dimming, phase-cut dimmable drivers, Casambi Bluetooth drivers, RF drivers and triac dimmers, and SceneCOM DALI-2 controllers.

Wall switches, remotes, a DALI-2 power supply and push-wire connectors complete the line-up. Trade account holders see trade prices, and in-stock orders placed before 5pm are delivered across Northern Ireland and ROI the following working day.

How to choose an LED driver or control system

Many LED problems, from flicker to early failure, trace back to a driver or dimmer that does not suit the load. Matching the electrical output and the control method gets the job right first time.

Match the driver to the LEDs

Output type – constant current drivers (rated in mA) suit downlights, panels and LED modules; constant voltage drivers (such as 24V) suit LED strip.
Current or voltage – the driver output must sit within the LED module's specified range.
Wattage – the driver should be rated for the total load, with headroom where recommended.
Size and IP rating – check the space available and whether the driver is suitable for the location.

Choose the control method

Phase-cut dimmable drivers work with compatible wall dimmers and suit domestic and small commercial jobs. 1-10V drivers dim from a separate low-voltage control signal and are common with sensors. DALI and DALI-2 drivers are individually addressable on a two-wire bus, allowing grouping, scenes and feedback in commercial buildings, and need a DALI bus power supply and controller. Push dimming lets a standard retractive switch dim and switch fittings. Casambi Bluetooth drivers allow app and wireless switch control without extra control wiring, and RF systems pair drivers with battery-powered wall switches and handheld remotes.

Installation tips

Keep control and mains wiring separated where the manufacturer requires it, observe polarity on DC outputs and keep drivers ventilated and accessible. Check the maximum cable length between driver and LED module. For strip installations see LED strip lights, and for presence and daylight control see motion detectors. Follow the manufacturer's instructions and current wiring regulations.

FAQ's Ask Your Own Question

What is the difference between a constant current and constant voltage LED driver?: A constant current driver supplies a fixed current, such as 350mA or 700mA, and lets the voltage vary to suit the LEDs; it is used for downlights, panels and LED modules. A constant voltage driver supplies a fixed voltage, such as 12V or 24V, and is used for LED strip and other loads designed for it. Using the wrong type can damage the LEDs.
What is DALI-2 lighting control?: DALI-2 is the updated version of the Digital Addressable Lighting Interface standard. Each driver or device on the two-wire bus has its own address, so fittings can be grouped, dimmed, scheduled and monitored individually. DALI-2 adds certified interoperability for control devices such as sensors and switches. A DALI system needs a bus power supply and a controller, such as the Kosnic SceneCOM range.
Do I need a leading edge or trailing edge dimmer for LEDs?: Most LED drivers and dimmable LED lamps are designed for trailing edge dimmers, which give smoother, quieter dimming at low loads. Some products also work with leading edge dimmers, but compatibility varies. Check the driver or lamp datasheet for the recommended dimmer type and the manufacturer's compatibility list, and make sure the total LED load is within the dimmer's minimum and maximum rating.
What is a Casambi LED driver?: A Casambi driver includes Bluetooth control, so fittings can be dimmed, grouped and set to scenes from a smartphone app or compatible wireless switches, without running extra control cables. It is a practical option for refurbishments, restaurants and retail spaces where rewiring is difficult. Kosnic offers Casambi dimmable drivers, some also supporting push-button control from a standard retractive switch.
What is push dimming?: Push dimming lets you dim and switch LED lighting using a standard retractive, or momentary, switch connected to the driver's push terminal. A short press switches the light on or off, and a long press dims it up or down. It is simple to install and useful in meeting rooms and classrooms. Check the driver's maximum number of fittings and cable length for push control.
Do I need a separate power supply for a DALI system?: Yes, a DALI bus needs its own power supply to provide the low-voltage signal that drivers and control devices use to communicate. Some controllers have a built-in bus supply, while others need a standalone unit such as the Kosnic DALI-2 power supply. Check the total number of devices on the bus and the power supply's rating against the system design before installation.
