Product Description


DC220V to DC48V10A DC/DC Converter 19inch 1U for communication use

Model: DD220T4810


DC/DC Converter is specially designed for meeting the requirements of all kinds of communication equipments of communication and electric power departments.

DC/DC Converter adopts the high frequency switching technology and has many good points, including high accuracy voltage stabilizing, low output noise, strong capacity of resisting disturbance, small volume, light weight, beautiful external shape, etc.


  • Input and output complete isolation, safety and credibility
  • Advance current control mode and stable & reliable circuit topological structure
  • The key parts all adopt the imported components, and main technical indexes are much higher than the national related standards
  • Strong protection functions: output over/under voltage, overcurrent, short-circuit and input over/ under voltage, and overtemperature protection
  • Adopt no-master automatic equalized current technology, can parallel connection, convenient to extend the capacity
