1. Non-Smooth Dimming

Symptoms: Light brightness changes in noticeable "steps" instead of transitioning smoothly.

Possible Causes:

Mismatched parameters between the dimming power supply and the fixture, or incorrect dimming method selection.

Poor PWM settings (e.g., low frequency or insufficient resolution).

Hardware incompatibility (driver module or signal protocol conflicts).

Signal interference (electromagnetic noise or power fluctuations).

Solutions:

Parameter Matching: Verify that the dimming power supply’s voltage, current, and power ratings align with the fixture’s requirements.

Upgrade Hardware: Use higher-quality dimming power supplies, such as Suretron’s DALI-2 Intelligent Dimming Power Supply, which delivers precise, stepless dimming.

Optimize PWM: Ensure PWM frequency is at least 20kHz to minimize visible flicker and step-like transitions.

2. Flickering Lights

Symptoms: Visible flicker during dimming.

Possible Causes: Poorly designed dimming power supply or lack of anti-flicker technology.

Solutions:

Anti-Flicker Power Supplies: Suretron’s dimming power supplies feature flicker-free designs to protect eye comfort and ensure stable lighting.

3. Compatibility Issues

Symptoms: Poor dimming performance or failure to dim.

Possible Causes: Mismatched parameters or protocols between the dimming power supply, fixtures, and controllers.

Solutions:

Verify Compatibility: Confirm voltage/current ranges and communication protocols (e.g., DALI, 0-10V) before purchasing.

Universal Compatibility: Suretron’s dimming power supplies adapt to most brands of fixtures and controllers for reliable performance.

4. Buzzing Noise During Dimming

Symptoms: Audible "humming" or "buzzing" from fixtures or the power supply.

Possible Causes: Unstable grid voltage or poor circuit design in the dimming power supply.

Solutions:

Check Voltage Stability: LED fixtures are sensitive to voltage fluctuations; ensure stable input voltage.

High-Quality Power Supplies: Suretron’s products use high-frequency PWM technology and optimized circuitry to minimize noise.

Wide Voltage Input: Suretron’s 100V-277V wide-voltage models ensure stable dimming even in unstable grid conditions.

While challenges with dimming power supplies are inevitable, understanding these issues and solutions empowers you to maintain optimal performance and enhance your lighting experience.
