从China供应商批发进口5v 40a 200w Led Power Supplies For Led Screens — FOB条款

The CL-A4-200-5 is a constant-voltage LED power supply delivering 5V at 40A with a maximum output of 200W, designed for LED screens and signage applications. It operates within an input voltage range of 190 to 264Vac at 50 or 60Hz, drawing a full-load AC current of ≤1.8A at 100Vac. The unit maintains a DC voltage tolerance of ±2% and achieves a typical efficiency of 79% at 220Vac input, with ripple and noise measured at 120mVp-p.

Constructed for industrial LED use, this model uses a switching power supply topology with built-in protections for overvoltage, overcurrent, and short circuits. The enclosure is typically aluminium for heat dissipation, a standard choice for 200W-class supplies in commercial LED installations. It adheres to common industry standards for LED drivers, including typical IP20 ingress protection for indoor use and a standard operating temperature range of -20°C to +60°C.

This power supply is suited for indoor LED displays, advertising boards, and backlit signage where stable 5V output is critical for consistent brightness and colour uniformity. Buyers in the LED signage sector often pair it with high-density LED modules requiring precise current distribution.
