Product identity

This JacobsParts LED-DIMMER-07 is a 12V RGB LED amplifier sold in a five-pack. It replicates the PWM signal from an existing strip so additional segments show identical colour and brightness while drawing power from a separate supply.

Best fit and limits

Installers who need to extend RGB runs beyond a single power supply will benefit from the bare-wire DC and dual 4-pin connectors. Buyers who want a standalone controller with user input or who require voltage other than 12V should look elsewhere.

Compatibility check

Verify that the existing strip operates at 12V and uses a four-pin RGB layout. Confirm the power supply can deliver up to 36W per channel for the added length. Ensure wiring polarity matches the amplifier’s bare-wire terminals before connecting.

Questions about this item

What power supply must I already have to run the 12V RGB amplifier?

You need a separate 12V DC power source rated for at least 36W per channel to feed the new strip.

Will the unit match colours from my existing 4-pin RGB strips?

Yes, it copies the PWM signal from the connected strip so the extended section shows identical colour and brightness.

How can I confirm the amplifier is reproducing the signal correctly?

Check that the extended strip changes colour and brightness in perfect step with the original strip.
