LTECH LA4 Waterproof LED Controller Instruction Manual

LTECH LA4 Waterproof LED Controller Instruction Manual

The LA4 is a high-performance 0/1-10V signal LED constant-voltage controller with IP67 waterproof rating, specifically designed for precise control of LED lighting fixtures. Supporting standard 0/1-10V dimming signal input, it features 4 signal input channels and 4 PWM load output channels to effortlessly meet diverse control scenarios. With robust output performance—delivering up to 20A maximum output current and 960W maximum output power—it reliably drives various LED constant-voltage armaturer.

By connecting 0/1-10V dimmers to channels 1-4, it flexibly enables dimming, color temperature adjustment, and full-color RGB/RGBW control for diverse lighting requirements. For user convenience, it supports both quick on/off, dimming, and color adjustment via button-operated digital displays, as well as advanced customization through the NFC Lighting app. This app allows configuration of dimming modes, fade times, dimming curves, PWM frequencies, and dimming ranges, balancing intuitive operation with deep customization.

Boasting IP67 waterproof performance and stable operation, the LA4 is suitable for diverse indoor and outdoor environments. It reliably functions even in humid conditions, delivering an efficient and flexible control solution for lighting systems.

Nøglebetjening

1. Power Key: Press once briefly to turn the light on or off.
2. Switch Key: Performs different operations based on the current device’s dimming interface.
   1. W: Remains in brightness adjustment mode; no action occurs with a short press.
   2. CT: Brightness (default)/Color Temperature, short press to toggle.
      After 2 minutes of inactivity, it will automatically return to the default state.
   3. Decrease/Increase Button: When the light is on, a short press cycles through settings one at a time. A long press continuously adjusts the current mode. No cycling function.
