Application Scenarios
How to Install & Configure the LT-834 Dimming Module
- Step 1: Disconnect Power - Before beginning installation, ensure the main AC power is turned off at the circuit breaker to prevent electrical shock.
- Step 2: Wire Connections - Connect the 100-240Vac power to the L (Live) and N (Neutral) input terminals. Connect the lighting load to the Triac dimmer output terminals. Connect your control signal (DMX, DALI, or Push switch) to the appropriate signal input terminals as shown in the datasheet diagrams.
- Step 3: Set DMX Address (If Using DMX) - Use the 9-position DIP switch to set the DMX initial address. The address is the sum of the values of the switches in the 'ON' position (1, 2, 4, 8, 16, 32, 64, 128, 256). For RDM mode, ensure all DIP switches are OFF.
- Step 4: Test Operation - Once all wiring is secure, restore AC power. Use your DMX console, DALI controller, or push switch to test the dimming functionality. A short press of a push switch toggles on/off, while a long press dims up or down.
- This product is for indoor use only.
- Ensure the total load does not exceed the maximum rating of 5A.
- Only use with luminaires compatible with forward phase-cut (leading-edge/Triac) dimming.
- Provide adequate ventilation around the module to prevent overheating.
- Please refer to the detailed datasheet in the Downloads section for complete wiring diagrams and DMX address settings.

Frequently Asked Questions
Q: What is forward phase dimming?
A:Forward phase-cut dimming, also known as leading-edge or Triac dimming, is a common method for dimming incandescent, halogen, and compatible LED lights. The LT-834 is specifically designed for this type of dimming.
Q: Does this module work with reverse phase dimming (ELV)?
A:No, this module is exclusively for forward phase-cut (leading-edge) dimming. It is not compatible with reverse phase-cut (trailing-edge/ELV) dimmers or loads.
Q: Can I use this with any LED bulb?
A:You must use LED bulbs or fixtures that are specifically marked as 'dimmable' and compatible with Triac or leading-edge dimmers. Non-dimmable LEDs will not work and may be damaged.
Q: How do I set the DMX address?
A:The DMX address is set using the 9 DIP switches. Each switch has a binary value (1, 2, 4, 8, etc.). Add the values of all switches in the 'ON' position to get your desired starting address.
Q: What happens if I connect both DALI and DMX signals at the same time?
A:The LT-834 has a built-in signal priority. It will always listen to the DALI signal first. If a DALI signal is present, it will ignore any DMX or Push DIM commands.
Q: What is the difference between this module and a standard DMX decoder?
A:This module outputs a high-voltage AC phase-cut signal to dim line-voltage lights directly. A standard DMX decoder typically outputs a low-voltage PWM signal to control constant voltage LED strip lights.
