Products You’ll Need
Before You Begin

Always practice S.A.F.E.T.Y. on the job site to protect yourself and your equipment:

S: Shut off power.

A: Ask a licensed electrician if needed.

F: Follow NEC guidelines.

E: Equip yourself with proper PPE.

T: Treat the wires as live.

Y: You are responsible.

This PWM dimmer is installed between a 12-24V DC power supply and your constant-voltage LED load.

Installation Steps

1. Prepare your wires: Strip the ends of your input and output wires.

2. Connect the power supply: Locate the side of the controller marked INPUT (CLASS 2). Connect the positive lead from your 12V or 24V DC driver to the (+) terminal. Connect the negative lead to the (-) terminal.

3. Wire the LED load: Locate the side marked OUTPUT (CLASS 2). Connect the common positive (+) wire from your LED strip to the top (+) terminals. Connect the corresponding negative wires to the appropriate channels (-R, -G, -B, -C, -W) depending on whether you are running single color, tunable white, RGB, RGBW, or RGBCCT.

4. Placement Mount the controller in an area where the operating temperature remains between -4°F to 122°F (-20°C and 50°C).

Pairing and App Configuration

1. Create a Network: To learn how to create a network and more about the Casambi app, check out the Casambi App Installation Guide.

2. Add the Device to Your Network

  • Add the Casambi touch panel and your lighting devices to the same Casambi network.
  • Open the Casambi App and tap "Nearby devices".
  • Nearby devices on Casambi app
  • Tap the PWM5-Pro in the list.
  • Tap "Add to (your specific network name)” to successfully add it to the network.
  • Add to Network on Casambi App

3. Select the available profile that matches your wiring (e.g., RGB+TW, RGBW, Tunable White, or independent channels).

Wiring diagram

For a fully utilized 5-channel RGBCCT setup, use the following connections:

Input: 12V DC or 24V DC to the (+) and (-) INPUT terminals.

Output:

  • (+) connects to Common (+) on the LED strip.
  • (-R) connects to Red (-).
  • (-G) connects to Green (-).
  • (-B) connects to Blue (-).
  • (-C) connects to Cool White (-).
  • (-W) connects to Warm White (-). Note: The maximum output current can be split across all connected channels or utilized by a single channel.

Troubleshooting

Flickering or erratic behavior: Verify that you are using a constant-voltage driver. The PWM5-Pro is engineered to provide a flicker-free lighting experience when paired with standard DC power.

Device shutting down: The device is protected against overload. Double-check that your total LED load does not exceed 5A on a 12V system or 4.16A on a 24V system.

App won't connect: Ensure the controller has power and is within Bluetooth range of your smart device.
