12V Pixel LED Belt (Patta) Complete Set — User Manual

This guide explains how to install, connect, and operate your Koshi Electronics 12V Pixel LED Belt Complete Set. The set arrives ready-made, so on-site assembly is minimal — just follow the steps below for a safe, reliable installation.

1. Box Contents

• 16 Bunch LEDs with 2-pin connectors
• 1 × Connection Belt (joins all 16 LED bunches)
• 1 × 12V 200W SMPS power supply
• 1 × 16-Channel Chaser controller

Covers a display area of approximately 20 ft (height) × 16 ft (width).

2. Before You Begin

• Choose a dry, sheltered spot for the SMPS and controller — keep both away from direct rain and water.
• Keep a 220V AC mains socket within reach of the SMPS.
• Basic tools: cable ties or clips for mounting, a screwdriver, and insulating tape.
• Make sure the AC supply is switched OFF while you wire everything up.

3. Installation — Step by Step

1. Mount the LED bunches. Fix the 16 LED bunches across your surface (building outline, gate, or shop front) following your 20 × 16 ft layout. Space them evenly for a balanced chasing pattern.
2. Connect bunches to the Connection Belt. Plug each LED bunch into its matching 2-pin connector on the connection belt. Each port corresponds to one channel of the chaser.
3. Connect the belt to the 16-Channel Chaser. Attach the connection belt's output to the controller's output terminals, keeping the channels in order.
4. Wire the Chaser to the SMPS. Connect the controller's DC input to the SMPS output — V+ to V+ (positive) and V− to V− (negative). Observe polarity carefully; reversed polarity can damage the board.
5. Connect the SMPS to AC mains. Wire the SMPS AC input — L (Live), N (Neutral) and Earth — to your 220V AC supply. Always use the earth terminal.
6. Power on and test. Switch on the mains. The LEDs will light up and begin running the built-in chasing animations automatically (see Section 4).

4. How the Animations Work

The 16-channel chaser comes pre-loaded with a fixed set of chasing animations. Once powered on, these animations play automatically — one after another — in a continuous repeating sequence.

• Automatic playback: The controller runs through all built-in animations on its own, with no setup required.
• Continuous repeat: When the sequence reaches the end, it starts again from the beginning and keeps looping.
• Please note: The animations cannot be locked or fixed to a single pattern. The controller is designed to cycle through every effect in sequence, one after another.

5. Power & Wiring Reference

6. Safety Guidelines

• Never connect the LEDs directly to 220V AC — they run on 12V DC only.
• Always match SMPS polarity (V+ / V−). Reversed polarity will damage the controller and LEDs.
• Keep the SMPS and controller in a sheltered, ventilated location, away from rain and water.
• Do not load the SMPS beyond its rated capacity.
• Switch off mains power before connecting or disconnecting any wiring.

7. Troubleshooting

• No LEDs light up: Check the AC supply, confirm the SMPS output is 12V, and verify DC polarity at the controller input.
• Some channels not working: Re-seat the 2-pin connectors on the connection belt and check for a loose bunch.
• Flickering or dim LEDs: Make sure the SMPS delivers a stable 12V and is not overloaded; tighten any loose connections.
• Animations not running: Confirm the controller has power and the DC connection from the SMPS is secure.

8. Care & Maintenance

• Inspect all connections before each festival or event season.
• Keep connectors dry; wipe away dust and moisture.
• Store the SMPS and controller indoors when not in use.

9. Warranty

6-month warranty on the 16-Channel Chaser controller against manufacturing defects only.* The 12V 200W SMPS power supply carries a 1-year guarantee. LED bunches are not covered under warranty.

*Not covered: physical damage, water damage, wrong SMPS polarity, connecting LEDs to 220V AC, or the SMPS/controller being exposed to rain.
