Constant current dimming power supply, three-output power supply

Constant current dimming power supply + three outputs = "One unit, three lights, brightness at your discretion."

Below is a complete technical package for a 24V 3×1A three-channel constant current dimming power supply, available for direct prototyping or OEM.

I. Core Specifications

 Input: AC 90-264V, 50/60Hz

 Output: 3 independent constant current 1A (customizable 0.3-3A)

 Dimming: 0-10V / PWM / Resistor / DMX512 (optional)

 Efficiency: ≥92% (synchronous rectification)

 Protection: Overvoltage, overcurrent, short circuit, open circuit, overtemperature

 Certifications: CCC / CE / RoHS / FCC

II. Three-Channel Independent Dimming Wiring Diagram

AC(L/N) → Power Supply → 3×(LED+ / LED-)
Dimming Signal → DIM1 / DIM2 / DIM3
Each channel can connect 1-10 LEDs (3V type), brightness 0-100% stepless adjustment. III. Performance Measurements

 Ripple: <50 mV (Oscilloscope 20MHz)

 Efficiency: 92% (230V input, full load)

 Temperature: Housing <60℃ (25℃ environment, full load 4 h)

 Protection: Open circuit, short circuit, over-temperature cut-off in 0.1 s

IV. Application Scenarios

 Stage Lighting: Three-way independent dimming for light strips

 Wall Washer Lights: RGB three-color independent control
