GAOHUI 12V 1500A 18KW IGBT Electroplating Rectifier with Microsecond Fault Response for Industrial Nickel, Chrome, and Zinc Plating

Key Features
– Precision Output: Provides adjustable DC voltage from 0 to 12V and current from 0 to 1500A, ensuring stable and repeatable electroplating results for high-volume production.
– High Efficiency: IGBT inverter technology delivers ≥90% energy conversion efficiency, reducing operational costs and heat generation compared to traditional SCR rectifiers.
– Digital Control: Integrated digital display for real-time monitoring of voltage and current, with local or remote control via push-button or HMI touch screen interface.
– Robust Construction: Designed for 24/7 industrial operation with forced air cooling and a durable cabinet, suitable for harsh plating environments.
– Variable Frequency Conversion: Advanced inverter stage converts high-voltage DC into precise, low-ripple output for uniform coating thickness on parts up to 3 sq ft.

Technical Specifications

Built-in Protection Systems
– Overvoltage Protection: Automatically shuts down output if voltage exceeds safe limits, preventing damage to plated parts.
– Overcurrent Protection: Limits current to 1500A maximum, with automatic shutdown on short circuit or overload.
– Overtemperature Protection: Thermal sensors trigger cooling fans and shutdown if internal temperature exceeds threshold.
– Microsecond-Level Fault Response: IGBT driver circuitry detects and isolates faults in less than 1 microsecond, safeguarding both rectifier and plating bath.
– Reverse Polarity Protection: Prevents connection errors that could damage sensitive plating processes.

Main Applications
– Electroplating: Ideal for nickel, chrome, zinc, copper, gold, silver, and hard chrome plating on steel parts up to 3 sq ft surface area.
