FAQ

What type of lighting systems is the Ltech LT-404-5A designed for?

The LT-404-5A is a constant voltage RGBW controller intended for LED lighting systems that use DALI or Push dimming control. It is suited for applications where separate RGBW channel control and smooth dimming performance are needed.

Which dimming protocols does the LT-404-5A support?

This model supports DALI and Push Dim control. It also uses PWM digital dimming and follows the standard DALI logarithmic dimming curve for consistent dimming behavior.

What are the output capacity and electrical ratings of the LT-404-5A?

The LT-404-5A supports an input and output voltage range of 12~24Vdc. It features 4 channels with a maximum current of 5A per channel (20A total) and a maximum output power of 480W.

How fine is the dimming range on this controller?

The dimming range is 0 to 100 percent. That makes this model a good fit for projects that require smooth brightness adjustment across the full spectrum.

Is the LT-404-5A appropriate for indoor or outdoor use?

This controller has an operating temperature range of -30 Β°C to 55 Β°C. It is designed for indoor environments.

Does this controller support multi-channel color control?

Yes, the LT-404-5A provides 4-channel control output for RGBW lighting control. That makes it appropriate for applications needing separate control across red, green, blue, and white channels.

How does the LT-404-5A compare with basic single-color dimming controllers?

Unlike a basic single-channel dimmer, the LT-404-5A is built for RGBW constant voltage lighting and offers 4-channel output. It also supports both DALI and Push dimming, which can make it a better fit for commercial lighting control environments.
