The Domus CHAM-BT-RF-5C is a 5-channel LED controller for1224V DC constant-voltage lighting, controllable byremote, touch wall panel or Bluetooth from a phone, and working withGoogle and Alexa. 1505030mm,48W at 12V or 96W at 24V.

This is a controller, not a driver and it needs one.Our catalogue files it under LED drivers, which is misleading in a way that matters.

The chain is three parts:

This is also the receiver the CHAM-REM-2C remote needs. That remote is sold in thiscatalogue under its own name and does nothing without this unit and because this one is listed asa Bluetooth RF 5-1 Universal Controller rather than by its CHAM code, nothing connectedthem. They are now cross-referenced from both pages.

Five channels, and what each configuration uses

• Single colour one channel. Dimming only.
• Tunable white two channels. Warm and cool LEDs mixed to any pointbetween.
• RGB three channels.
• RGBW four channels: colour plus a dedicated white.
• Five channels covers all of them, which is what universal means here one controller for whatever strip you end up using, rather than a different unit per type.
• RGBW is worth understanding: a dedicated white channel gives a proper white,where mixing red, green and blue to make white gives a colour cast. If the strip will spend most of itslife on white, choose RGBW.

Three ways to control it, and they coexist

• RF remote no line of sight needed, so the controller can be hidden in aceiling void or behind joinery.
• Touch wall panel for a fixed position, which is what most people actuallywant in a living room.
• Bluetooth from a phone, with the app and Google and Alexaare supported, which is stated plainly in Domus’s own description.
• A wall panel plus a phone is usually the right combination. The panel is whatguests and family use; the phone is for scenes and scheduling.

The load limits, and why they differ by voltage

• 48W at 12V, 96W at 24V.
• The controller is current-limited, not power-limited at twice the voltageit carries twice the power for the same current. That is another reason to run 24V ratherthan 12V wherever the strip allows it.
• Work out the load before ordering. A 10W/m strip at 24V gives youroughly 9metres on one controller; a 20W/m strip gives roughly 4.5m.Tell us the strip and the run length and we will check it.
• The driver must be sized above the load as well, and it is a separate item.

Installing it

• 1505030mm small enough to sit ina ceiling void, in a joinery cavity or beside the driver.
• IP20 it needs a dry, protected position. Not in a bathroom cavity that canget damp, and not outdoors.
• RF and Bluetooth mean it does not need to be visible, which is the point of hidingit but do not bury it where it cannot be reached. It is an electronic part andit will outlive neither the building nor, necessarily, the strip.

Where it works

• Tunable-white, RGB and RGBW LED strip installations at 12 or 24V DC.
• Where control needs to be by wall panel, remote and phone together.
• Smart-home installations Google and Alexa supported.
• Not a driver a constant-voltage driver is still required upstream.
• IP20 a dry, protected, accessible position.
• Check the load against 48W at 12V or 96W at 24V.

Specifying it

CHAM-BT-RF-5C 5-channel LED controller.1505030mm, IP20.For 1224V DC constant-voltage lighting.Maximum load 48W at 12V, 96W at 24V.Five channels single colour, tunable white, RGB or RGBW.Controlled by RF remote, touch wall panel or Bluetooth; works with Google and Alexa.

A constant-voltage LED driver is required upstream and is not included, and the LEDstrip is separate again. This is the receiver the CHAM-REM-2C remote requires.Warranty 3 years.

Questions

Is this a driver?

No, and our catalogue files it misleadingly. It is a controller: it sits between a constant-voltage driver and the LED strip and does the switching, dimming and colour mixing. The chain is three parts a driver converting 240V mains to 12 or 24V DC, this controller, and the strip. The driver and the strip are both separate purchases.

Is this the receiver the CHAM remote needs?

Yes. The CHAM-REM-2C remote sold in this catalogue does nothing without this unit, and because this one is listed as a “Bluetooth RF 5-1 Universal Controller” rather than by its CHAM code, nothing connected the two. They are now cross-referenced from both pages. If you have the remote and it appears not to work, this is the part you are missing.

How much strip can it run?

48W at 12V or 96W at 24V the controller is current-limited rather than power-limited, so at twice the voltage it carries twice the power. In practice a 10W/m strip at 24V gives you roughly 9 metres on one controller and a 20W/m strip roughly 4.5 metres. Tell us the strip and the run length and we will check it, and size the driver at the same time.

What does “5 channel” actually give me?

One controller for whatever strip you end up using. Single colour uses one channel, tunable white two, RGB three and RGBW four so five covers all of them. RGBW is worth understanding: a dedicated white channel gives a proper white, where mixing red, green and blue to make white gives a colour cast. If the strip will spend most of its life on white, choose RGBW.

Does it work with Google or Alexa?

Yes both, stated plainly in Domus’s own description. That is worth noting because it is unusual in this catalogue: another connected Domus product, the CFA-SWM fan Wi-Fi module, has no voice-assistant support recorded anywhere at all.

How should I control it day to day?

A touch wall panel plus the phone app is usually the right combination. The panel is what guests and family use without needing an app; the phone is for setting scenes and schedules. An RF remote is the third option and does not need line of sight, which is what lets the controller itself be hidden.

Where should it be installed?

Somewhere dry, protected and importantly reachable. At 150 50 30mm it fits in a ceiling void, a joinery cavity or beside the driver, and because it uses RF and Bluetooth it does not need to be visible. It is IP20, so not a damp bathroom cavity and not outdoors. Do not bury it behind sealed joinery: it is an electronic part and it will not outlive the building.
