Abstract

Silicon Carbide Power Adapter LED lighting model uses constant-current architecture for commercial LED fixtures. Silicon Carbide Power Adapter achieves ±2% current accuracy, ripple current below 3% and supports 0-10V dimming. Silicon Carbide Power Adapter wide-voltage input and high efficiency suit commercial lighting and luminaire manufacturer power supply.

1. Constant-Current Electrical Parameters

Silicon Carbide Power Adapter LED model accepts 100–277VAC input, 50/60Hz, compatible with North American 277V commercial grid. Silicon Carbide Power Adapter constant-current output 42V/2.1A, rated 90W, output current accuracy ±2%. Silicon Carbide Power Adapter peak full-load efficiency 95.3%, PF≥0.96, switching frequency 120kHz. Output ripple current of Silicon Carbide Power Adapter is limited under 3% to prevent LED flicker and visible strobing. No-load standby power of Silicon Carbide Power Adapter ≤0.15W, meeting lighting energy standards.

2. Dimming Compatibility & Control Interface

Silicon Carbide Power Adapter supports 0-10V analog dimming with 1%~100% range and no flicker throughout. Built-in dimming receiver of Silicon Carbide Power Adapter continuously adjusts output current based on dimming signal. Silicon LED drivers often suffer brightness jitter and color shift at low dimming levels. Optimized loop bandwidth of Silicon Carbide Power Adapter delivers smooth current at deep dimming without LED flicker. Silicon Carbide Power Adapter also accepts PWM digital dimming for smart lighting control systems.

3. Environment & Lifetime

Silicon Carbide Power Adapter operating temperature -30℃~+60℃ for outdoor street lights and factory high-temperature environments. Long-life electrolytic capacitors of Silicon Carbide Power Adapter rated ≥50,000 hours @25℃. Running at 60℃ ambient, Silicon Carbide Power Adapter maintains efficiency above 91%. Class II double insulation of Silicon Carbide Power Adapter requires no ground wire for simple installation.

4. Protection & Lighting Certifications

Silicon Carbide Power Adapter includes output open-circuit protection, short-circuit protection, overtemperature protection and overvoltage protection. When LED load disconnects, Silicon Carbide Power Adapter auto-limits current to prevent overvoltage damage. Certifications include UL8750, CE, FCC, CB for global luminaire配套. Silicon Carbide Power Adapter MTBF≥60,000 hours reduces lighting system maintenance cost.
