60V 500A High Frequency IGBT Anodizing Rectifier for Hard Anodizing

Key Features
– IGBT switching technology ensures ultra-stable DC output with less than 1% ripple, critical for uniform oxide layer growth during hard anodizing.
– Microsecond-level fault response time protects both the rectifier and the anodizing tank from sudden short circuits or overcurrent events.
– GAOHUI proprietary digital control system supports constant current (CC) and constant voltage (CV) modes with programmable ramping for precise anodizing cycles.
– RS485 communication interface enables remote monitoring and integration into automated production lines, reducing manual intervention.
– Compact rack-mount design with forced air cooling delivers 30KW continuous power without overheating, even in harsh industrial environments.

Technical Specifications

Built-in Protection Systems
– Overvoltage protection with automatic shutdown triggers within 10 microseconds to prevent damage to the anodizing bath.
– Overcurrent protection with foldback current limiting ensures safe operation during load variations.
– Over-temperature protection activates a cooling fan speed increase and power reduction if internal heat exceeds safe limits.
– Short circuit protection with latching fault indication allows quick troubleshooting and reset.

Main Applications
– Hard anodizing of aluminum alloys for aerospace, automotive, and military components requiring thick, wear-resistant oxide layers.
– Anodizing titanium and stainless steel parts where precise voltage control is needed for color anodizing or functional coatings.
– Electroplating and electropolishing processes that demand high current density and stable DC output.
– Laboratory research and development for custom surface treatment experiments and process optimization.
