Thyristor module and diode module instead of power electronics device parameters, such as chip environment condition has a very close relationship, work in high altitude and low temperature environment, the user needs to pay attention to the reasonable use, ensure working device in a reliable way.
40 ℃ condition, thyristor
module of gate trigger current value to double than 25 ℃, gate trigger voltage increases about 30%, thus to ensure the reliable equipment start, needs enough strength of thyristor module gate triggering current.
When we require the user to adopt strong trigger measures.
It also to improve the device of di/dt performance, reduce the loss of opening time and opening, conducive to devices in series, in parallel operation plays an important role.
It is recommended to use the gate trigger condition is: gate trigger current amplitude IG = 10 igt (
The gate current open time tr≤
Under the condition of high altitude, air cooled radiator cooling capacity decreased, but the lower environmental stability and is advantageous to the heat dissipation device, so it is possible that in use should be according to the site of zui high ambient temperature device and the selection of radiator, to leave the current allowance.
If the device is very frequent start, stop, in - devices frequently
Between 125 ℃ temperature cycle, the reliability and life expectancy of the device will be less than the normal work, should be paid attention to in use.
Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, thyristor module, solid state relay 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.
