DC5V40A 200W LED Switching Power Supply

  • Universal switching mode power supply. Input: AC 110V / 220V, 50 / 60Hz ; Output: DC 5V, Max 40A, 200W. The default output voltage is 5V DC, but it can be regulated by 10%, from 4.5V to 5.5V. Three sets of output channels available.
  • It can supply with all amperage less than 40A. —such as 1A, 8.5A, 18A, 30A, 40A. For example, if your device draws 35A, then 35A will be supplied. If draws more than 40A, only 40A will be supplied and power supply will be damaged soon. NEVER OVERLOAD!
  • We focus on producing high quality power adapters. No noise, low temperature operation, no spontaneous combustion, no explosion, no fire hazard, stable output. Automatic overload cut-off, over voltage cut-off, automatic thermal cut-off, short circuit protection.
