The 9000A 18V Water-cooled Synchronous Rectifier Power Supply (N+1 Parallel Configuration: 3 Units) delivers ultra-stable high-current DC output. Its N+1 redundant parallel structure guarantees continuous production even if one module fails.
The 9000A 18V Water-cooled Synchronous Rectifier Power Supply (N+1 Parallel Configuration: 3 Units) is an ultra-high current industrial rectifier built for uninterrupted heavy-duty plating and electrolysis operations. Unlike single-unit high-current rectifiers, this solution uses three modules working in N+1 parallel redundancy. For example, if one module encounters a minor fault, the remaining two modules can still maintain operation, so your production line will not shut down completely. Many traditional single high-current rectifiers force full line stoppage once the unit breaks down. As a result, factories face costly downtime and lost batches. Thermal overload also causes output instability, which creates inconsistent coating or electrolytic reaction results and increases waste.
The 9000A 18V Water-cooled Synchronous Rectifier Power Supply (N+1 Parallel Configuration: 3 Units) supports smooth stepless adjustment from 0 to 9000A current and 0 to 18V voltage. It works well for large-scale rack plating, metal electrolytic extraction and heavy metal surface treatment workflows. In addition, each independent module is fitted with closed-loop circulating water cooling. It quickly dissipates heat during long continuous production cycles and keeps the whole system within safe temperature ranges around the clock. High-precision closed-loop control balances current sharing across all three modules. It stabilizes DC output automatically when load conditions shift, ensures uniform current distribution and keeps electrolyte bath conditions steady. Furthermore, each module carries independent multi-layer safety protection to guard internal hardware against overload, overheating and sudden short-circuits.
· Provides 9000A 18V stepless adjustable DC output, constructed with 3 modules in N+1 parallel redundancy for ultra-high current industrial processes.
· Implements synchronous rectification topology with balanced current sharing. In turn, it cuts power loss and reduces overall heat generation during long production runs.
· Features independent water cooling for every module. Hence, the whole system handles heavy thermal loads and supports non-stop 24-hour batch manufacturing.
· Supports CC and CV operation modes. Operators can switch smoothly for bath activation, formal electrolytic processing and post-production quality checks.
· Comes with individual protection circuits for each module. It limits the impact of single-module faults and avoids total production shutdown.
· Equipped with RS485 communication on each unit. With it, operators monitor every module’s real-time data and store logs to optimize production recipes.
In fact, many large metal finishing and electrolytic plants still rely on single high-current rectifiers. Those single machines create huge operational risks because any component failure stops the entire line. Even so, the 9000A 18V Water-cooled Synchronous Rectifier Power Supply (N+1 Parallel Configuration: 3 Units) fits perfectly for factories that cannot afford unexpected downtime. Many production lines run non-stop batches with changing workpiece surface area or electrolyte conductivity, and this modular setup adapts well to these real working scenarios. Our team performs full-load ageing and current balance testing for every module before shipment. Therefore, the complete system maintains stable performance over repeated long production cycles.
The built-in current balance algorithm automatically distributes load evenly across three modules. Changing working temperature and bath conditions often trigger small output deviations. This system compensates in real time to maintain precise current and voltage output. As a result, you reduce scrap rates and avoid financial losses caused by sudden equipment halt. The system can store multiple groups of process parameters. Operators can quickly recall saved process presets. This action shortens equipment setup time and improves overall workshop productivity.
Each module uses a reinforced sealed cabinet paired with anti-corrosion water circulation pipelines. This modular assembly delivers strong dust-proof, moisture-proof and anti-corrosion performance. Accordingly, it runs reliably in humid and corrosive environments inside plating and electrolysis workshops. Moreover, the three-phase AC input stays stable and each module adopts rugged mechanical construction. This parallel rectifier system has low failure probability and long service life to meet strict uninterrupted mass-production demands.
