ITG Power Supply

Specifications

ITG Power Supply with highly efficient, flexible and reliable features

Introduction:

The 48V series of the rectifier is a new generation of rectifiers that is developed by New Zealand Shi Witke's company, using the technology of RTT-HF-resonant soft-switching electronic variable than the patented.

 

With the world's leading high-frequency switching technology, combined with the smart air-cooled high-reliability method. And with highly efficient, flexible and reliable features, which is to become the core components of DC power supply.

 

ITG rectifier, being able to adapt to higher environmental temperatures (up to 70), and a very wide AC input range, and it could be well adapted to the access network in which to harsh environmental conditions.

 

ITG rectifier loading in a typical efficiency is greater than 91%, and the optimal performance, with power factor correction circuits, the power factor closes to 1, so it is in a typical application with a very low operating costs.

 

ITG rectifier built-in CPU, can be replaced online and automatically communicate with the system, all settings are automatical, without human intervention.

 

ITG rectifier is very safe and reliable, with the microprocessor circuit of the fail-safe backup, adjustable current limit point, with high-temperature load shedding and over-voltage auto shutdown to protection, and short circuit protection function.

 

Features:

1. Very wide range of AC input voltage

2. All intelligent microprocessor-controlled

3. The software automatically set all the parameters, easy to maintain

4. High power density

5. The flexible, modular design, convenient system expansion

6. Quick replacement, without hand-tune

7. Constant power output to meet the communication needs of modern equipment

8. Wide range of DC output

9. With the real live hot-swap

10. With highly reliable intelligent temperature-controlled air-cooled

11. Meet the international standards
