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
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:
Since it built in driver,the installation is very easy than normal dimmer switch, you needn't buy another LED driver any more.
• GND (GREEN): To ground wire in box.
• V+ (RED): To low voltage V+.
• V− (WHITE): To low voltage V−.
• N (WHITE): To 120 V Neutral.
• H (BLACK): To 120 V Line Hot.
TROUBLESHOOTING
1.Fixture does not illuminate
• Incorrect wiring. Polarity of Low Voltage V+ and V- are reversed.
• Circuit breaker is OFF or tripped.
• Incorrect voltage pairing of dimmer and fixture. 12 V dimmer models will not power a fixturewith a higher voltage rating.
2.
• Different fixtures do not dim in sync.
• Fixture turns off at low dim level.
• Fixture strobes/flickers at low dim level.
• Dimmer buzzes excessively
Only install 12 V or 24 VDC tape lights on the compatibility list.
3.Fixture heats up excessively
• Incorrect voltage pairing of dimmer and fixture. Do not attach a 12V fixture to a 24V dimmer.
• Fixture is not compatible.
