PWM Electroplating Rectifier

• Operation mode: local/remote operation mode can be chosen
• Output control mode: constant current/constant voltage output control mode can be chosen
• Soft star 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 thyristor rectifier
• IGBT inverter switch frequency: 20KHZ-25KHZ
• Rectifier efficiency ≥92%
• Output current ripple coefficient ≤1-3%
• Master controller: DSP computer digital PWM pulse width modulation control, pulse phase resolution ≤1us
• Main protection functions: deficient phase, overvoltage, under voltage, quick 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 power component, switch rectifier transformer, quick rectifier diode component and BUS copper bar, overheating and high pressure protection of wind machine, low block PWM trigger pulse protection.
• Communication interface: CAN BUS, PROFIBUS, ETHERNET, RS485 and RS232 optical fiber communication can be chosen to realize remote control or monitor according to customer’s requirements
• Rectifier transformer’s iron core adopts quality nanocrystalline material, no-load loss less than 2%, 4-5%energy-saving comparing with common switch rectifier transformer
• The remote control operation is more convenient, the anti-corrosion protection of most increase significantly
• Super small volume and weight, weight 1/5-1/8 of thyristor rectifier, weight is 1/20-1/40 of thyristor rectifier
