Working Principle & Dimming Technology

DC dimmers adjust light source brightness by modifying current or voltage, performing voltage conversion and stable current control. Two primary dimming technologies are employed:

PWM (Pulse Width Modulation): Adjusts LED brightness by altering duty cycle to control average current
Linear Dimming: Controls current through LED by modifying input voltage or current detection resistor resistance

Key Advantages

Flicker-free & Silent Operation: Advanced PWM technology eliminates flickering and reduces noise
High Efficiency: Exceptional reliability with extended operational lifespan
Multi-Channel Common Anode: Supports multiple LED lamp configurations
Precision Dimming: 0.1% adjustment accuracy for optimal lighting control

Application Scenarios

Indoor Lighting: Residential, office, and commercial spaces
Outdoor Lighting: Street, landscape, and public area illumination
Automotive Lighting: Vehicle interior and exterior lighting systems
Stage Lighting: Performance and event lighting solutions
Advertising Displays: LED billboards and informational displays
Smart Lighting: IoT-enabled lighting control systems

Installation Guide

With built-in driver, installation is simpler than standard dimmer switches (no additional LED driver required):

GND (GREEN): Connect to ground wire in box
V+ (RED): Connect to low voltage V+
V− (WHITE): Connect to low voltage V−
N (WHITE): Connect to 120 V Neutral
H (BLACK): Connect to 120 V Line Hot

Troubleshooting

Fixture does not illuminate:
- Check for incorrect wiring (polarity of Low Voltage V+ and V- may be reversed)
- Verify circuit breaker is ON and not tripped
- Ensure correct voltage pairing (12V dimmer won't power higher voltage fixtures)
Dimming issues:
- Different fixtures not dimming in sync
- Fixture turns off at low dim level
- Fixture strobes/flickers at low dim level
- Excessive dimmer buzzing
Fixture heats up excessively:
- Verify correct voltage pairing (don't attach 12V fixture to 24V dimmer)
- Check fixture compatibility
