Application Scenarios
How to Wire & Install This DALI Driver
- Step 1: Verify Compatibility - Ensure your LED lights are rated for 24V DC Constant Voltage. This driver is designed for resistor-based loads like most standard 24V LED strip lights.
- Step 2: Calculate Your Load - Sum the total wattage of all connected LED lights. For optimal performance and driver longevity, it is recommended to keep the total load at or below 80% of the driver's capacity (80W for this model).
- Step 3: Wire AC Input - With power disconnected, connect your 200-240V AC source to the driver's input terminals. Connect the Live wire to 'L' and the Neutral wire to 'N'.
- Step 4: Wire DC Output - Connect the output terminals to your LED lights. Wire the positive (V+) terminal to the positive input on your LEDs, and the negative (V-) terminal to the negative input. Always check polarity.
- Step 5: Connect Control Wires - For DALI control, connect the two DALI bus wires to the 'DA' terminals (polarity insensitive). For Push DIM control, connect a normally open momentary switch across the 'Push DIM' terminals.
- Step 6: Power Up & Test - Once all connections are secure, restore power to the circuit. Test the on/off and dimming functions using your DALI controller or push switch.
⚠ Precautions
- Installation should be performed by a qualified electrician in accordance with local regulations.
- Always disconnect the main power supply before wiring or servicing the driver.
- Ensure adequate ventilation around the driver to dissipate heat and prevent overheating.
- DALI signal takes priority over Push DIM if both interfaces are connected simultaneously.
- This driver is optimized for constant voltage LED strip lights. For fixtures with built-in constant current ICs (like some MR16 lamps), please contact us for a compatible firmware version.

Frequently Asked Questions
Q: What is a DALI LED driver?
A:A DALI LED driver is a smart power supply that converts AC mains voltage to low-voltage DC for LEDs, while also allowing for digital control over dimming and on/off functions via the DALI (Digital Addressable Lighting Interface) protocol. To learn more, read our guide on What Is DALI Dimming?.
Q: Can I use this driver without a DALI controller?
A:Yes. This driver features a Push DIM interface, allowing you to control dimming and on/off functions using a standard, cost-effective momentary wall switch.
Q: What is the difference between this and a standard non-dimmable LED power supply?
A:A standard power supply only provides power. This DALI driver both powers your 24V LEDs and provides sophisticated, smooth, flicker-free dimming control, integrating your lights into a smart control system.
Q: Is this DALI driver truly flicker-free?
A:Yes. It uses a high 3600Hz PWM frequency, which is well above the threshold of human perception and standard cameras, ensuring a stable light output that won't flicker on video recordings.
Q: How many feet of 24V LED strip can I connect to this 100W driver?
A:This depends on the wattage per foot of your LED strip. To calculate, divide 80 (80% of 100W) by the strip's watts-per-foot rating. For example, if your strip is 4.4 W/ft, you can run approximately 18 feet (80 / 4.4 ≈ 18.1).
Q: Is this a suitable LED driver replacement for my old one?
A:Yes, if your lighting system requires a 24V Constant Voltage driver with a capacity of 100W or less and you want to add DALI or Push DIM control, the LM-100-24-G1D2 is an excellent upgrade or replacement.
Q: Will this work with my 12V LED strip lights?
A:No. This driver has a fixed 24V DC output and is only compatible with 24V LED lighting products. Using it with 12V strips will permanently damage them.
