Overview

LD4 is the 4Γ—(12-48)VβŽ“ output model of this series.

The LD4 is a high-performance LED constant-voltage controller with IP67 waterproof rating. It receives standard DALI protocol signals and is compatible with all DALI systems on the market, specifically designed for precise control of LED lighting fixtures. Featuring 4 channels, it delivers a maximum output current of 20A and a maximum output power of 960W, enabling stable operation of various LED constant-voltage fixtures. Parameters such as DALI address, dimming curve, dimming range, dimming ramp time, color temperature range, power-on status, system failure status, and DALI templates can be quickly configured via the DALI master controller or NFC Lighting app. The DALI address can also be manually set via buttons and displayed on the digital tube. Basic operations like quick switching, dimming, and color adjustment are supported through the button-operated digital tube, balancing intuitive operation with deep customization. The LD4 flexibly enables dimming, color temperature adjustment, and full-color RGB/RGBW control for diverse lighting needs, integrating 8 DT6/DT8 device types: RGBW, RGB+W, XY+W, RGB, XY, 2*CT (synchronous control), 2*CT (asynchronous control), and 4*W. Device types can be switched via the NFC Lighting app. With IP67 waterproofing and stable performance, the LD4 is suitable for diverse indoor and outdoor environments, reliably operating even in humid conditions to deliver efficient, flexible control solutions for lighting systems.
