Output: 18V DC / 20000A (360kW)
Core Tech: N+1 Redundant Modular Design
Key Process: Automatic Periodic Reverse (PR)
Cooling: Water Cooling
Our hard chrome power supply delivers 20000A 18V with an N+1 redundant design. Specifically, it serves heavy-duty industrial hard chrome plating that runs continuously under high loads.
The water cooling system maintains stable performance during long hours of full-load operation. Furthermore, the N+1 modular structure effectively prevents production downtime and greatly improves overall system reliability.
It provides steady high-current, low-voltage output to form dense, uniform, and wear-resistant hard chrome coatings. In addition, we engineer this unit to solve common industry pain points such as unstable output, high ripple, and poor heat dissipation.
Its corrosion-resistant structure works reliably in harsh workshops with acid mist and high humidity. As a result, it acts as a stable power core for large-scale hard chrome plating lines.
Our hard chrome power supply uses advanced high-frequency IGBT technology. Consequently, it reaches over 92% energy efficiency and reduces long-term operating costs.
The unit maintains extremely steady current and voltage even at full 20000A load. Moreover, this stability directly improves coating uniformity and reduces common defects like uneven thickness and poor adhesion.
The dedicated water cooling system rapidly dissipates high-power heat. As a result, it controls temperature rise and avoids unexpected overheating shutdowns.
This design extends component life and lowers maintenance frequency. Additionally, we use anti-corrosion materials and sealed structures to withstand harsh plating environments.
The N+1 redundant system keeps production running even if one module needs service. Meanwhile, the user-friendly control system supports manual adjustment and PLC/RS485 automation linkage.
These features boost production efficiency and cut labor costs. Furthermore, we fully customize each unit to match your process, workpiece size, and production schedule.
