DC110V to DC24V40A DC DC Converter
DC110V to DC24V40A DC DC Converter
Model: DD110T2440
Introduction:
DC/DC Converter is specially designed for meeting the requirements of all kinds of communication equipments of communication and electric power departments, which 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.
The DD110T2440 use the PWM (pulse width modulation) technology with automatic current sharing function and N +1 backup function (N+1 combination of modules structure), which can be used in parallel. When the power supply module failure, it can safely auto-exit and alarm, which ensure that the power supply system works normally.
Features:
With N +1 backup function
Input and output complete isolation, safety and credibility
Advance current control mode and stable & reliable circuit topological structure
Using the inside air-cooling methods, with lower noise
High reliability, Maintain Simply, quickly and easily
Strong protection functions: output over/under voltage, overcurrent, short-circuit and input over/ under voltage, and overtemperature protection
EMC characteristics: Consistent with the standard EN55022 CLASS B & IEC61000-4 LEVEL 3
