Medium frequency inverter DC resistance welding controller ZMF800
Controller advantages:
1. The three-phase power input and the filter capacitor inside the controller make the three-phase current balance and less pollution to the power grid;
2. The control frequency is 1kHz, the current control is more rapid and accurate, and the output current density is high;
3. The welding current rectified by the intermediate frequency transformer is DC, and the inductive reactance in the welding circuit has little influence on the welding current;
4. Greatly reduce the volume and weight of welding transformer;
5. Effectively reduce electrode wear rate and increase electrode service life;
6. Good welding effect can be achieved for metal materials such as brass, aluminum, galvanized plate, high-strength steel, etc;
7. Precise current control, reduce spatter rate and effectively improve the quality of solder joints.
1. The output frequency of the power supply is 1kHz, and the time accuracy is ms level;
2. Up to 31 sets of welding specifications can be stored, and the power-off storage time can be up to 10 years;
3. Three stage heating process: preheating, welding and tempering; the welding section can realize the function of increasing and decreasing current; the welding section can define up to 99 pulses;
4. Programmable output port: free programming for three output periods, better adaptation with other devices;
5. It has the functions of total solder joint count, number of printing points and production number monitoring;
6. It has the function of current monitoring, which can set the upper limit and lower limit of current alarm, and alarm if the current exceeds the limit;
7. Integrated spot welding and seam welding functions, with single point / continuous function during spot welding;
8. It has the function of fault diagnosis and protection. If the controller detects any abnormality, it will automatically shut down the output and prompt the fault code;
9. The high performance DSP chip is used as the main control unit, which greatly improves the system reliability;
10. With 485 communication interface and standard Modbus communication protocol, it is convenient to connect configuration panel, industrial control computer, PLC and other equipment for remote control.
11. With constant phase angle, constant current control mode, accurate current control;
