Rectifier Equipment for Electroplating
JB/T 1504--93
Replaces JB1504-75
This standard specifies the type, basic parameters, technical requirements and test methods of rectifier equipment for electroplating. This standard applies to rectifier equipment for electroplating that does not convert polarity and requires output polarity conversion (including diode rectifier equipment with voltage regulator, saturated reactor voltage regulation and rectifier equipment with voltage regulation using crystal tube, power transistor, etc., hereinafter referred to as equipment). It can also be applied to DC power supply equipment for anodizing and low-voltage electrolysis.
This standard does not apply to pulse electroplating power supply equipment. 2 Reference standards
