Product Description

1. CE approved dc dc converter
2. Optimize control circuit design
3. Over voltage protection
4. Remote failure alarm


48V to 12V DC power supply converter for communication and electricity use is widely used in the area of communication and electricity. This product is mainly designed to meet the need of the requirements of all kinds of communication devices. Adopted Unmanned automatic equalized current and high accuracy switching technology, our converter can accept both AC and DC input and the AC and DC electricity can be fully isolated.


1. Separated Input and output, safer and more reliable
2. Advance current control mode
3. Stable & reliable circuit topological structure.
4. Low output noise
5. Strong capacity of resisting disturbance
6. Small Dimension, Light weight
7. Intelligent self-protection system (output over/under voltage, over current, short-circuit and over temperature )
8. N+1 redundancy structure
9. Converter module input EMI circuit, no interference and less pollution to power.
10. Pulse width modulation and resonance technology, input and output is completely isolated.
11. Optimize control circuit design, high efficiency, low noise and light weight.
12. Over voltage protection and remote failure alarm.


Parallel DC-DC converter used advanced high frequency edge of the pulse width modulation (PWM) resonance technology, efficiency has been greatly improved. Use for pagers amplifier, electricity systems, cluster system, mobile communication base stations and other telecommunications systems applications.
