Casambi CV LED Driver Technology

How Casambi enabled constant voltage drivers bring wireless Bluetooth control to 12V, 24V and 48V LED strip, and how to choose the right one.

Snappy SCL series Casambi enabled constant voltage LED driver

Overview

What is a Casambi CV LED driver?

A Casambi enabled constant voltage (CV) driver is a 12V, 24V or 48V DC LED power supply with a Casambi Bluetooth Low Energy radio built in. It powers LED strip, linear lighting and signage, and can be switched, dimmed and grouped from the Casambi app on a phone or tablet, or from Casambi compatible wireless switches. There is no control wiring and no gateway is needed.

Our Casambi CV range is the Snappy SCL series: slimline linear drivers rated at 100W and 150W with 12V, 24V or 48V outputs. The SCL150 dims from 1% to 100%, reaches up to 93.5% efficiency, and has a built-in push dimming input for a standard wall push switch.

The technology

How Casambi CV control works

Every Casambi driver is a node in a Bluetooth Low Energy mesh. Each node relays messages to its neighbours, so a command from the app or a switch reaches every driver, even those out of direct range of the phone.

Drivers are commissioned in the Casambi app, where they are named and grouped into rooms, scenes and timers. The settings are stored in the network, so the lights keep working without the phone.

Each driver holds a steady 12V, 24V or 48V output and dims the LED strip to the requested level. A wired push switch adds local on/off and dimming, and drivers linked in the app dim together.

Simplified illustration: the app, a wireless switch or a wired push switch sets the level, and each driver dims its 24V LED strip; commands hop between drivers across the mesh.

Benefits

Advantages of Casambi CV LED drivers

Why Casambi is a popular way to add smart control to LED strip.

No control wiring

Drivers talk to each other over Bluetooth, so only mains power is needed at each driver.

No gateway needed

The self-forming mesh is commissioned and controlled straight from the app.

Easy set-up

Group strip runs, create scenes and set timers in the Casambi app, and change them at any time.

Push dimming

A standard retractive push switch gives local on/off and dimming alongside the app.

12V, 24V or 48V

Choose 48V for long strip runs with less voltage drop, or 12V and 24V to match existing strip.

Slim linear case

Just 30mm wide and 18.2mm high, for coves, bulkheads and furniture.

Selection & set-up

Choosing and installing a Casambi CV driver

Match the voltage: use a 12V, 24V or 48V driver to match the strip.
Size the power: add up the strip load (W/m × length) and allow at least 20% headroom; the 12V SCL150 is rated at 132W.
Limit voltage drop: on long runs, feed the strip from both ends or choose 48V strip.
Plan the mesh: keep drivers within Bluetooth range of each other, and avoid fitting them inside enclosed metal housings.
Commission in the app: add each driver to a Casambi network, then group strip runs and create scenes.
Add switches: use Casambi wireless switches, or wire a push switch to the push dimming input.

FAQ

Casambi CV driver questions

A Casambi constant voltage (CV) driver is a 12V, 24V or 48V DC LED power supply with a Casambi Bluetooth Low Energy radio built in. It powers LED strip or linear lighting and can be switched, dimmed and grouped from the Casambi app or Casambi compatible wireless switches, with no control wiring.

No. Casambi drivers form a Bluetooth mesh in which every driver relays commands to its neighbours, so the system is set up and controlled directly from the app. A gateway is only needed for remote control or monitoring over the internet.

Yes. The Snappy SCL series has a built-in push dimming input for a standard retractive push switch: a short press switches the light on or off and a long press dims. When several drivers are dimmed together, they are linked in the Casambi app, and Casambi wireless switches can be used as well.

Match the driver to the strip voltage. 24V strip is the most common choice for general lighting, and 48V strip allows longer runs with less voltage drop because it draws half the current of 24V strip for the same power. 12V suits short runs and low-voltage fittings.

Add up the strip load in watts (watts per metre multiplied by length) and choose a driver rated at least 20% above that total. For example, 8m of 14.4W/m strip draws 115W, so a 150W driver is the right choice. Note that the 12V SCL150 is rated at 132W.
