• Main protection functions: AC power phase loss, overvoltage, undervoltage, fast fuse blowing alarm and circuit breaker protection; output overcurrent, current limit protection, output short circuit, instantaneous overload protection; IGBT switch module, fast rectifier components, switching rectifier transformer, busbar copper bus overtemperature and overheating, fan overheating or water pressure is too high/low, blocking PWM trigger pulse protection.
• Communication method: CAN bus, PROFIBUS, ETHERNET industrial Ethernet, RS485, and RS232 optical fiber communication can be configured according to customer needs to achieve remote group control or monitoring.
• With 1-5 stages of constant current slow rise and slow down stage number control, each stage oxidation current and oxidation time can be set separately.
• Real-time recording of multiple process parameters and real-time curves such as forward and reverse current / voltage, pulse current/voltage amplitude, pulse duty cycle, pulse frequency, oxidation time, bath temperature, etc.
• Remote operation control box: The remote operation control box can be configured according to the customer's site conditions, the plating rectifier machine and the remote control box are separated to prevent, the field operation is more convenient, and the rectifier's corrosion protection is significantly enhanced.
• 5 sets of process parameters can be stored or recalled to shorten the processing programming time.
• Can be connected to the computer through the RS485 communication interface, or stored in the U disk and transferred to the computer, which is convenient for the customer to save the file and analyze the product process quality of the oxidized workpiece.
• Workpiece coating quality: Compactness, smoothness and corrosion resistance are significantly better than the ordinary plating process.

Tips: 3000A plating rectifier troubleshooting

1. The abnormal noise of the 3000A plating rectifier occurs. This kind of situation is mostly seen in the air-cooled rectifier fan failure or the accumulation of dust. It should be cleaned in time to avoid affecting the normal operation of the entire machine.

2. The working indicator is normal, but thet current and voltage cannot be adjusted. It is worth noting whether the adjusted voltage and current have exceeded the minimum and maximum values that the power supply can carry or whether the adjustment switch has been turned to the lowest or highest position. The current should be adjusted under the condition of steady voltage and the voltage should be adjusted under the condition of steady current. 

3. During the working process, the current output is suddenly interrupted, but when the work instructions and the voltage and ammeter display are normal, it is generally due to a problem with the wiring between the power supply and the plating tank. Check the wiring between the power supply and the tank in a timely manner Connected.
