Product Details

350A350V AC to DC Plasma torch heating rectifier

1. Suitable plasma torch heating rectifier

The IGBT power supply is suitable for DC non transfer arc and DC transfer arc.

2. Difficult points of plasma heating application rectifier

  -Multiple plasma load type: from resistive, capacitive, inductive, resistive-capacitive, resistive-inductive load, power supply need to adapt to these load. 

  -High voltage impulse to power supply: power supply should withstand this impulse, need special circuit design

  -Plasma negative resistance characteristic: power supply should match this load feature. 


3. What's special of Green Power rectifier

 -High quality, Europe level reliability with much cheaper price than Europe

 -Experience of plasma torch load

 -Good solution to the plasma application, high voltage withstand circuit design

 -Easy remote control, support 4-20mA/0-10V analog signal+dry contacts, communication RS485(MODBUS)

 -Touch panel HMI

 -Excellent workmanship

 -Custom design available
