ITG Power Supply

ITG Power Supply
Product Detailed
ITG Power Supply with highly efficient, flexible and reliable features


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.
