48V to 5V Isolated DC-DC Converter

Product description

48V to 5V isolated DC-DC power converter is suitable for 5V electrical equipment such as vehicle LED screen, surveillance camera, fan, water pump, motor, router, etc. Built-in overvoltage, overcurrent, overheating, short circuit and other multiple protections; the internal circuit board is safer and more reliable to use.

When using a power MOSFET as a rectifier, the gate voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification. It can greatly improve the efficiency of the DC-DC converter.

Isolated DC-DC converter


  • The performance is stable; the module shell is made of flame-retardant silicone, which generates little heat during use.
  • Isolated between input and output.
  •  High efficiency: 92%.
  • Imported capacitors, high reliability.
  • 100% full load burn-in test.
  • Over temperature protection, over-current protection, over-voltage protection, short-circuit & reverse protection, epoxy potting, waterproof protection.
  • Aluminum shell, surface mountable. Cooling by free air convection.
