The Heavy Duty Anodizing Rectifier from Gaohui Rectifier delivers 4000A at 20V for heavy-duty aluminum anodizing. This Heavy Duty Anodizing Rectifier powers a wide range of oxidation racks with stable DC or pulsed output. Furthermore, the Heavy Duty Anodizing Rectifier uses water cooled IGBT stages that hold tight output stability under full load. Consequently, oxidation shops rely on it for uniform, repeatable coatings. Moreover, surface-finishing facilities select this Heavy Duty Anodizing Rectifier for its water cooled design and 4000A 20V capacity that keeps deposition rates predictable. Consequently, production planners factor it into daily schedules without derating concerns.
Cooling: Water cooled | Application: Heavy-Duty Aluminum Anodizing | Ripple: ≤5% | Interface: RS485/PLC
The 4000A 20V rectifier is a workhorse for general aluminum anodizing lines. It coats architectural parts, cookware, electronics housings and extrusions. For example, a rack of extrusions receives even decorative oxide ready for dyeing. Furthermore, stable output supports dyeing and sealing downstream. Moreover, water cooling sustains high-volume shifts. In addition, the PLC interface ties it to the anodizing line.
Moreover, this rectifier offers load-tracking DC metering for quality records. In addition, overcurrent foldback protects parts and unit on shorts. Consequently, anodizing plants depend on it for repeatable daily throughput. Moreover, process engineers value the fieldbus integration. Finally, Gaohui supports energy recording for cost-per-part analysis.
