(1) rated voltage
The broken state repeated peak voltage U. When the gate is broken and the junction temperature is rated, it is allowed to repeat the positive peak voltage on the device. Reverse repetitive peak voltage: when the gate circuit is broken and the junction temperature is rated, it is allowed to repeat the reverse peak voltage on the device. Usually take SCR and smaller values as the rated voltage of the device. When selected, the rated voltage should have a certain margin, and generally the rated voltage is 2~3 times the peak voltage of the thyristor when it is working normally.Industrial Furnace Oven Lab Heating Equipments Quality High Vacuum Brazing Furnace
(2) rated currentrefractory metal smelting furnace
The average value of the maximum power frequency sinusoidal half wave current allowed by the SCR under the ambient temperature of 40 ~ C and the prescribed cooling state is less than the rated junction temperature. When using the principle that the actual current is equal to the effective value of the average current of the pass state, the SCR should be chosen not to leave a certain margin, which is generally 1.5 to 2 times.
