Thyristor module damage, if not same thyristor
module replacement, can choose with its performance parameters are similar to other types of thyristor to substitution.
Application circuits are usually leave when the design bigger margin.
When replacement thyristor module, as long as the attention to its nominal peak voltage (
Repetitive peak voltage)
, rated current (
State the average current)
, the gate trigger voltage and gate trigger current, especially peak rated voltage and rated current of these two indicators.
Substitution thyristor should be consistent with the damage of the thyristor switch speed.
For example: in the pulse circuit, high-speed high-speed thyristor inverter circuit used in damage, can only choose the same type of thyristor, fast and can not use ordinary thyristor to substitution.
Select alternative thyristor module, no matter what parameters, don't have to have big margin, should as far as possible with the substitution of thyristor module parameters, because too much allowance is not only a kind of waste, and sometimes the side effects, don't trigger or triggering the phenomenon such as insensitive.
In addition, also notice the appearance of two thyristor module should be the same, otherwise it will bring bad installation work.
Zhejiang production of various kinds of specifications models of thyristor rectifier module, thyristor module, solid state relay module, the diode module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, to provide affordable, quality and reliable electronic components.
come in many forms, like silicon rectifier diode and silicon rectifier, and they all provide efficient solution for our silicon rectifier diode needs.
Yangzhou Positioning Tech. Co., Ltd’s purpose is to create superior value for our customers, employees, communities and investors through the production, conversion, delivery and sale of energy and energy services.
Though the cost of these sustainability initiatives as custom rectifier can be high, harnessing the power of an ethical supply chain to appeal to conscientious consumers can be a smart move both ethically and financially.
custom rectifier has obtained many affirmation in the market. Undoubtedlly, our customers are totally satisfied with our products.
