It seamlessly integrates into any standard DALI lighting system, decoding digital signals to provide smooth, flicker-free dimming from a subtle 0.1% to full brightness. Uniquely, it also provides a simultaneous 0-10V output for each channel, offering exceptional flexibility for hybrid control systems. This makes the LT-408-5A the ideal choice for demanding commercial, architectural, and high-end residential projects that require a reliable and powerful digital lighting control system. To better understand the protocol, you can learn more about What Is DALI Dimming?. It pairs perfectly with a central DALI master controller to manage any compatible single color LED strip lights.

Key Features

High-Capacity 8-Channel Control

Independently manage up to eight separate zones of LED lighting for complex, layered lighting designs.

Dual DALI & 0-10V Signal Output

Offers unparalleled versatility by providing both DALI-controlled PWM output for LEDs and a corresponding 0-10V analog signal for other fixtures.

Powerful 5A Per Channel Output

Delivers a strong 5A current on each channel, capable of driving long runs of LED strips or high-power fixtures without voltage drop issues.

Wide Voltage Compatibility

Operates on both DC 12V and DC 24V systems, making it adaptable to a wide range of common LED products.

Precision 0.1-100% Dimming

Achieves exceptionally smooth, flicker-free dimming across the entire range, from a near-imperceptible glow to full intensity.

Robust and Reliable Build

Housed in a durable metal casing with a wide operating temperature range, ensuring long-term performance in professional environments.

Dual-Output System Flexibility

The LT-408-5A stands apart with its dual-output architecture. For each of its 8 channels, it simultaneously provides a constant voltage PWM output (5A) to directly power LED strips and a 0-10V analog signal output.
This unique capability allows you to build sophisticated hybrid systems. You can drive your primary LED zones directly from the PWM outputs while using the 0-10V signals to control other compatible drivers, dimmable ballasts, or fixtures, all synchronized from a single DALI command.

How to Control & Use This DALI Driver

Ensure all power is disconnected before wiring.
Connect your DC 12V or DC 24V power supply to the main power input terminals (V+ / V-).
Wire the DALI bus lines (DA+ and DA-) from your DALI master controller to the driver's DALI input terminals.
Connect the positive and negative wires of your LED fixtures to the corresponding CH1 through CH8 output terminals, ensuring correct polarity.
If using the 0-10V feature, connect the signal wires from your 0-10V compatible devices to the corresponding 0-10V output terminals.
Power on the system. Use your DALI master controller to scan for new devices and assign a DALI address to the LT-408-5A.
Once addressed, test each channel to confirm dimming control and proper operation.

⚠ Precautions

Verify that the input voltage of the driver (12V or 24V) matches the operating voltage of your LED lights.
Do not exceed the maximum load of 5A per channel or the total power capacity of the driver (480W for 12V systems, 960W for 24V systems).
Incorrect wiring or reverse polarity can permanently damage the driver and/or your LED fixtures.

Frequently Asked Questions

Q: What is the primary function of the LT-408-5A driver?

A:The LT-408-5A is a DALI decoder that receives commands from a DALI master controller to precisely dim up to 8 independent channels of constant voltage LED lighting.

Q: Can I control eight different single-color LED strips with this one unit?

A:Yes, its 8 independent channels are perfect for controlling eight separate zones or individual single-color LED strips.

Q: What is the purpose of the 0-10V outputs?

A:In addition to driving LEDs directly via PWM, it outputs a corresponding 0-10V analog signal for each channel. This allows it to control other devices that use 0-10V for dimming, offering excellent system flexibility.

Q: Do I need a DALI master controller to use this driver?

A:Yes, this is a DALI slave device and requires a DALI master or a DALI-compatible automation system to send it control signals.

Q: What is the maximum length of LED strip I can connect to one channel?

A:This depends on the power consumption (Watts per meter) of your LED strip. Each channel supports up to 5A. At 24V, this is 120W per channel (24V x 5A). Divide 120 by your strip's W/m rating to find the maximum length.

Q: Is this driver suitable for RGB or RGBW LED strips?

A:This model is designed for 8 individual channels of single-color control. For multi-color strips, you would need a dedicated DALI driver with grouped channels, such as a 4-channel RGBW DALI decoder.
