Overview

LM4 is the 4Γ—(12-48)V βŽ“ output model of this series.

The LM4 is a high-performance LED constant-voltage controller with an IP67 waterproof rating, designed for precise control of LED lighting fixtures. It receives standard DMX/RDM protocol signals and features 4 channels with a maximum output current of 20A and maximum output power of 960W, enabling stable operation of various LED constant-voltage lighting fixtures. The LM4 offers flexible dimming, color temperature adjustment, and RGB and RGBW full-color control to meet diverse lighting needs. It has both DMX decoder mode and DMX master mode. In DMX decoder mode, you can set parameters such as DMX address, resolution, PWM frequency, dimming fade time, and dimming mode. The DMX master mode can set 33 lighting effects, speed, brightness and other parameters. You can switch modes and configure various parameters within each mode via three methods: the NFC Lighting app, the RDM-WIFI app, or the pushbutton, balancing intuitive operation with deep customization. With IP67-level waterproof performance and stable operation, LM4 can be widely used in various indoor and outdoor environments. It can work reliably even in humid scenes, providing efficient and flexible control solutions for lighting systems.
