Simple type 3 phase thyristor power regulator SCR3-LA Operation Warning
?
The main circuit adopts three-phase four-wire input without requirement for phase sequence.
For SCR is a product with a high current, please keep in mind that terminals of R,S,T and U,V,W be locked tightly, or SCR will be burned by terminals’ heating.
When Y connection is used for three-phase load, the center of Y should be connected with zero line, if not so, relative equilibrium of the three-phase is required.
During the use of module, when the load power is more than 15KW, it& acute;s best to be equipped with proper radiator, and heat conducting silicon grease should be coated between radiator and SCR backboard with wind cooling.
?
Module protection: Please use semi-conductive fast fuse for load over current.
Remark: When the?working power is more than 15KW,please keep in mind that the radiator should be??used??frequently.?
