The High Voltage MAO Rectifier from Gaohui Rectifier delivers 5A at 1000V for 1000v high-voltage mao. This High Voltage MAO Rectifier powers a wide range of oxidation racks with stable DC or pulsed output. Furthermore, the High Voltage MAO 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 High Voltage MAO Rectifier for its water cooled design and 5A 1000V capacity that keeps deposition rates predictable. Consequently, production planners factor it into daily schedules without derating concerns.
Cooling: Water cooled | Application: 1000V High-Voltage MAO | Ripple: ≤5% | Interface: RS485/PLC
The 5A 1000V rectifier is purpose-built for micro-arc oxidation, where the bath voltage climbs into the plasma range of several hundred volts. It grows hard ceramic oxide coatings on aluminum, magnesium and titanium alloys. For example, it coats engine components, aerospace parts and medical implants to over 100 microns. Furthermore, the high-voltage output sustains the micro-arcs that form dense alumina. Moreover, pulsed control refines pore structure and lowers energy use. In addition, the RS485, optional PLC port allows remote monitoring.
Moreover, this rectifier supports ramp-up profiles that prevent spark runaway on fresh parts. In addition, water-cooled cooling keeps output stable through long MAO cycles. Consequently, customers use it for wear-resistant, corrosion-protective ceramic coatings on light alloys. Moreover, operators appreciate the clear controls on this unit. Finally, the Gaohui service team responds quickly to spare-part requests, which keeps the line running.
