The HA4 is a high-performance constant-voltage LED controller designed for precise lighting control using standard 0/1-10V dimming signals. It features 4 signal input channels and 4 PWM output channels, supporting flexible control for a wide range of LED applications.
With up to 6.4A per channel and a total output power of 1536W, the HA4 reliably drives constant-voltage LED fixtures. By connecting 0/1-10V dimmers to channels 1-4, it enables smooth dimming, tunable white, and full RGB/RGBW control.
Basic operations such as on/off, dimming, and color adjustment can be managed via the onboard digital display, while advanced settings like dimming curves, fade times, and ranges can be configured using the NFC Lighting app. With an IP67 waterproof rating, the HA4 is suitable for both indoor and outdoor installations, even in humid environments.
