FAQ

What type of product is the Ltech LT-401-15A?

The Ltech LT-401-15A is a single-channel constant voltage DALI2 LED controller for professional indoor lighting applications. It is designed to provide precise dimming control for constant voltage LED loads across a 12-48VDC range.

What voltage and output capacity does the LT-401-15A support?

This model supports an output voltage range of 12-48VDC and delivers up to 15A output current. Its maximum output power is 720W, making it suitable for higher-load constant voltage LED control applications.

Does the LT-401-15A support very low dimming levels?

Yes, the LT-401-15A offers 0-100% dimming with an ultra-low dimming level down to 0.1%. It uses PWM digital dimming, which helps preserve LED colour rendering while maintaining smooth control.

Is the LT-401-15A compliant with DALI standards?

Yes, the LT-401-15A supports the DALI bus standard and is compliant with IEC62386-101, IEC62386-102, and IEC62386-207. That makes it a strong fit for commercial and professional lighting systems requiring DALI2 compatibility.

What can be adjusted through the NFC setting feature?

The LT-401-15A supports NFC configuration through the NFC Lighting App or an NFC programmer. Available settings include DALI address, dimming curve, PWM frequency, and other advanced parameters supported by the device.

Where is the LT-401-15A typically used?

This model is intended for indoor LED lighting environments where DALI2 dimming and stable constant voltage control are required. Its higher 15A output and configurable NFC settings make it suitable for professional lighting projects with more demanding control requirements.

What protection features does the LT-401-15A include?

The LT-401-15A includes protection against short circuit, overtemperature, overcurrent, and reverse polarity conditions. These protection functions are designed for safe, reliable operation and support automatic recovery where applicable.

What operating environment and warranty does this controller have?

The LT-401-15A includes a 5-year warranty, which is useful for commercial buyers looking for longer-term product support.
