PWM-DY Electroplating Rectifier

• Operation mode: local/remote operation mode can be chosen
• Output caontrol mode: constant current/constant voltage output control mode can be chosen
• Soft start time: Working time of soft start can be set between 0-200s
• Constant current/constant voltage control accuracy: ≤±1%
• Rectifier mode: IGBT inverter soft switch rectifier, 5% energy-saving comparing with common switch rectifier power supply, 15-25% energy-saving comparing with thvristor rectifier
• IGBT inverter switch frequency: 20KHZ-25KHZ
• Output current ripple coefficient≤3%
• Human-computer interface: PLC colorful touch screen
• Master controller: DSP computer digital trigger control, PWM pulse width regulation control, pulse phase-shifting resolution≤1us
• Main protection functions: lack phase, overvoltage, under voltage, quick fuse or fuse alarm protection of AC power supply, output over current and current limiting protection, output short circuit and instantaneous overload protection, over temperature and overheat protection of IGBT switch module, quick rectification caomponent, switch rectification transformer and bus copper bar, overheating and high pressure protection of wind machine, low block PWM trigger protection
• Communication means: CAN BUS, PROFIBUS, ETHERNET, RS485 and RS232 optical fiber communication can be chosen to realize remote control or monitor according to customers’requirements
• With 1-5 stage constant current slow rising and slow descending stage number control, every stage oxidation current and time can be set respectively
• Real-time record process parameters and curve of current, voltage, anodizing time and bath temperature etc
• Can store or withdraw 5 sets of process parameters, shorten machining and programming time
• Can be connected with computer through RS485 communication interface, or store by U disk then restore to computer, it is convenient for clients to keep file and analyze product process quality of oxidation parts
• Iron core of rectification transformer adopts good quality super microcrystalline material, no-load loss less than 2%, which is 4-5%, electric-saving comparing with common on-off rectification transformer
• Remote control operation box: remote operation control cabinet can be choose according to customer’s situation on site, hose and remote control cabinet are placed separately, on-site operation is more convenient, anti-corrosion protection of increased greatly
• Ultra small size and weight, size is just 1/5-1/8 of silicon controlled rectifier, weight is 1/20-1/40 of silicon controlled rectifier
