Collingwood PR3002 24V Power Repeater for RGBW LED Strip (Requires Driver)

A Quiet Box That Keeps Long Colour Runs Honest

Push a colour changing LED strip far enough down a run and the far end starts letting you down. Brightness tails off, the whites go slightly grey, and a colour that looked clean at the first metre looks tired at the last. The Collingwood PR3002 is the answer to that. It is a 24V power repeater for RGBW LED strip that takes the four colour signal arriving from the controller and sends it onward at full strength.

There is nothing decorative about it, and that is rather the point. It has no lens and no light output of its own. Its entire job is to let one controller cover far more ground than it could manage alone, then disappear into the void once the boards are back on.

The White Plastic Module

The PR3002 comes as a slim white plastic case, 170mm long by 58mm wide and only 28.5mm tall, weighing around 0.2kg. That low profile matters more than it sounds, because these units almost always end up in a shallow ceiling void, a plinth recess or the back of a cabinet where there is very little depth to play with.

Screw terminals run along both long edges. One side takes the 24V DC input and the incoming RGBW signal, the other side carries the four colour output through to the next length of strip. Each terminal is printed on the lid, so the wiring is legible at a glance rather than something you have to work out from a folded sheet. A moulded fixing lug sits at either end, with a screw hole so the unit can be fastened down flat instead of being left loose in a ceiling.

How It Works

A Collingwood colour changing system needs three things: a C100924 controller to decide the colour, a separate 24V DC driver to supply the power, and the strip itself. The PR3002 slots in between. It reads the RGBW signal coming in from the controller and reproduces it faithfully on its own output, using fresh power drawn from the driver on its DC input rather than whatever is left in the line. Collingwood publishes a rating of 39W per channel at 24V across its four outputs.

Repeaters are wired in parallel from the controller rather than chained one behind another, which is why the signal stays strong however many you add. Collingwood states that up to 100 units can run from a single C100924 controller, covering as much as 1000 metres of LED strip per zone. The unit is supplied on its own, so the driver, the controller and the strip are all specified separately. It runs at 24V extra low voltage on the secondary side, but the driver feeding it is a mains connection, so this is work for a qualified electrician.

Where It Works Best

This is a component rather than a fitting, so the question is less which room and more where in the build it lands. Typical homes for it are long cove and coffer details that wrap a whole ceiling, staircase and handrail runs across several floors, perimeter lighting in a bar or reception, and kitchen schemes where strip runs under the wall units, along the plinth and inside glazed cabinets from one controller.

It is also the piece that makes larger garden and facade schemes practical, where colour changing strip runs the length of a terrace or around a building and a single controller could never hold the signal that far. In every case the repeater itself gets mounted somewhere dry and reachable: a ceiling void with an access hatch, a cabinet carcass, a plant room, a utility cupboard, or a suitable weatherproof enclosure if the strip it feeds is outside. Leave it accessible. It is far easier to fault find on a unit you can actually reach.

About Collingwood Lighting

Collingwood designs and manufactures its LED products in Sywell, Northamptonshire, and has worked in LED technology since 2002. The brand states it was among the first to bring fire rated, fully sealed for life and mains dimmable LED products to the UK electrical wholesale market. It also holds an EcoVadis Gold medal, which places it in the top 5% of companies assessed for sustainability worldwide. Accessories like the PR3002 are the unglamorous end of that catalogue, and they are built the same way as the fittings they serve.

Good to Know

• Warranty: 3 years.
• IP20 rated, which means no protection against water at all. It must sit in a dry position indoors, or inside a suitable weatherproof enclosure if it forms part of an outdoor scheme.
• Electrical class: Class III. The repeater works on 24V DC extra low voltage and is never wired straight to mains.
• A separate 24V DC driver is required. The repeater relays the signal and passes power through, it does not generate power or convert mains voltage.
• Built to work with the Collingwood C100924 colour change controller, with up to 100 repeaters supported from one controller.
• Housing: white plastic, 170mm long by 58mm wide by 28.5mm high, around 0.2kg.
• The unit label gives an operating temperature range of minus 20C to plus 50C.
• This item is listed as non returnable, so check the system design and the number of repeaters needed before ordering.
• Care: keep the terminals covered and the unit ventilated, and wipe with a dry cloth only if it is ever exposed during other work.
• Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

Does the Collingwood PR3002 need a separate driver?
Yes. The Collingwood PR3002 power repeater generates no power of its own, so a separate 24V DC driver is required to feed both the repeater and the LED strip connected to its output.

How many PR3002 repeaters can one controller run?
Collingwood states that up to 100 PR3002 power repeaters can be controlled from a single C100924 controller, which allows a colour changing scheme to cover as much as 1000 metres of LED strip per zone.

Are power repeaters wired in series or in parallel?
Collingwood PR3002 power repeaters are wired in parallel from the controller rather than chained one behind another, so every repeater receives the same signal directly and the run can be extended without the colour weakening along its length.

Can the PR3002 be installed outdoors?
The Collingwood PR3002 is rated IP20, so it has no protection against moisture and must be installed in a dry location or inside a suitable weatherproof enclosure, even when the RGBW LED strip it feeds is running outside.

What is the output rating of the PR3002?
The Collingwood PR3002 has four output channels running at 24V DC, rated at 39W per channel in Collingwood's own published specification, which is what allows it to drive a further length of RGBW strip beyond the controller.
