• 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: What caused the output of the plating rectifier to be suddenly interrupted?

When the plating rectifier power supply output is suddenly interrupted during the work process, and the protection indicator flashes, this situation is generally caused by the power supply system entering the protection state. At this time, it should be divided into the following situations:

1. Due to the overheat protection function, that is, there is a problem with the electroplating rectifier cooling fan or water cooling device. At this time, the cooling device can be checked to eliminate the failure of the fan and water cooling and the normal use can basically be restored.
2. The overcurrent protection function may be caused by the excessive output current of the power supply, which causes the electroplating rectifier to enter the overcurrent protection state. In this case, you only need to restart the rectifier.
3. Overvoltage, undervoltage and phase loss protection caused by output voltage, check whether the input is normal.
4. Due to the short circuit or the damage of the components in the circuit, professional maintenance personnel should be notified to deal with it. In this case, there will generally be a smell of burnt, because there will be certain burns regardless of whether the short circuit or the damaged components , will produce a paste smell.
