The adapter's compact form factor (101*44*32mm) makes it ideal for space-constrained installations. The matte black housing provides excellent heat dissipation while maintaining a professional appearance. The integrated strain relief on the DC cable ensures long-term durability even with frequent plugging and unplugging.

Wide Applications

This 12V power supply is designed for versatility. It powers SMD2835, 3528, and 5050 RGB LED strip lights, LED strings, wireless routers, ADSL cats, network hubs, switches, security cameras, and audio/video equipment. The stable 12V output with ≤120mV ripple ensures clean power for sensitive electronics.

The product label clearly displays all technical parameters and safety certification marks. Each unit is individually tested and serialized for full traceability. The UL, CUL, FCC, CE, and CB certifications ensure compliance with international safety standards for global market distribution.

Safety Features

Built-in protection circuitry includes Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP). In the event of a fault, the adapter enters safe mode and automatically recovers once the fault clears—no manual reset required.
