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:
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 fixture with 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.
