Abeltronics DIM12N LED Dimmer 10A 12V/24V with Potentiometer (Negative Output)

The Abeltronics DIM12N is a low-voltage 12V or 24V PWM lamp and LED dimmer module (up to 10A, 120W at 12V / 240W at 24V) controlled by the included external rotary potentiometer. The unit features a negative low-side output, making it ideal for high-power RGB LED dimming applications with a common anode or common positive connection.

Utilizing 240Hz Pulse Width Modulation (PWM), it provides smooth flicker-free operation and exceptional energy efficiency (>97%). In the event of an open circuit between the dimmer and potentiometer, the output automatically defaults to full brightness as a fail-safe measure. Compatible with any standard 10k linear potentiometer or resistive sensors (such as thermistors or LDRs).
