Description

1) Mainly is refers to the thyristor and the electric valve module; 2) According to module ledger wall whether (popular name bottom strap not charged) can divide into for the electrode: The insulation and the non-insulation (mainly uses in welding in power source) two big kinds; 3) Divide into according to the module interior core quantity: The list (tube core) the module, the pair (tube core) the module, three (tube core) the module, four either six core module (mainly is single-phase or three-phase rectification bridge module); 4) Divide into according to the module interior core type: Thyristor module, electric valve module and electric valve/Thyristor mixed type module.
