DC24V to DC48V15A DC/DC Converter 19inch 2U Rack for communication use

 

Model: DD24T4815

 

Introduction:

 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.

 

Features:

• 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
