V1-KF 4 Channel RF LED Dimmer Controller 12–48VDC 4 x 4A

V1-KF 4 Channel RF LED Dimmer Controller

The V1-KF is a compact and versatile 4-channel constant-voltage LED controller designed for smooth manual dimming with optional 2.4GHz RF wireless control. With four dedicated rotary knobs, digital display, scene recall, selectable PWM frequency and dimming curve options, it is ideal for professional LED strip, cabinet, display and architectural lighting systems.

Suitable for 12-48VDC constant-voltage LED lighting, the V1-KF delivers up to 4A per channel across four independent outputs, making it a practical solution where multiple single-colour LED circuits need direct and reliable brightness control.

Description

The V1-KF is designed for installations that need simple, dependable control over multiple constant-voltage LED channels. Each channel is adjusted independently via its own front-panel rotary knob, giving installers and end users direct tactile control without the need for a complicated interface.

The built-in digital display and function keys allow access to additional setup options including RF matching, PWM frequency selection, dimming curve selection and scene storage. This makes the unit suitable for both straightforward manual dimming and more advanced RF-based lighting control systems.

When used as a controller, the V1-KF can directly dim four separate LED output channels. It can also work as a 4-zone RF remote interface, allowing pairing with compatible RF dimming controllers for flexible multi-zone lighting installations.

Selectable PWM frequencies of up to 8000Hz make it a strong choice where smoother visual performance is desired, including in applications sensitive to camera flicker. The selectable linear or logarithmic dimming curve also allows the dimming response to be tuned to suit the application and user preference.

Typical Applications

• Single-colour LED strip lighting
• Cabinet and joinery lighting
• Retail display lighting
• Architectural feature lighting
• Multi-channel LED control panels
• OEM lighting systems
• Wireless RF-controlled LED installations

Technical Specifications

Important Note

This controller is intended for constant-voltage LED loads and provides four independently dimmed output channels with a common positive supply. It is best suited to single-colour LED circuits requiring separate channel control.
