Power scope: 10kW-3000kW
Frequency scope: 50kHz-800kHz
Rated DC voltage: 450V
Power grid voltage: 220V~450V,50/60Hz,3-phase

Full digital rectifying control board
The new generation of solid state welding machine, using the field programmable logic gate array (FPGA) main control chip, the main frequency up to 100M, 16 bit A/D conversion chip (the original control board using 8 bit A/D conversion chip), the high precision of the data resolution; the cancellation of all the adjustable potentiometers on the board (12 control potentiometers in the original control board), color touch screen control System and parameter setting, deb ing and operation are simple and intuitive. All parameters in the rectifier board can be transmitted to the host computer for display and recording through communication. The unique parallel working mode of FPGA ensures that the modules of the program operate at high speed and independently. 

All digital inverter control board
The new generation of solid state high frequency welder has integrated the advanced control concept of similar products in the world. The field programmable logic gate array (FPGA) is used as the main control chip to realize the advanced control technology such as the fixed angle lock phase control, the upper / lower frequency locking protection and so on, which makes the equipment running more stable and more efficient. 

The new bridge inverter technology design
The new technology inverter bridge plate is made of the 12mm purple copper plate surface plating technology and the oval inner channel cooling, the surface of the water cooled plate is more smooth and the cooling effect is better. The temperature of the power element is better than the original inverter bridge under the same environment (using the tin plating process of the 5mm thick purple copper plate and the surface welding copper tube cooling mode) Low 3~5 degrees Celsius improves the safety of power devices.
