Three-phase 40kW digital induction heating products, which adopt the fifth-generation digital processing platform technology of our company, embedded 32-bit processing system, full digital phase-locked frequency tracking, with coil intelligent identification technology, and automatically adjust the output strategy to achieve the purpose of identifying different coils. The interface is rich and supports standard Modbus RTU communication protocol, which can easily realize touch screen man-machine dialogue and remote control. Moreover, it has the advantages of fast-tracking speed, high precision, strong adjustability, strong coil adaptability, convenient installation, simple debugging, etc. it can be widely used in various pipeline heating, such as plastic machinery (such as injection molding machine, wire drawing machine, granulator, extruder in the energy-saving transformation process), food machinery, crude oil transportation, boiler, heat-transfer oil, heating, and other similar heating industries.

1,Connect the power supply voltage of the cooling fan, but connect the 220V power when the fan is 220V, and connect the 380V power when the fan is 380V 2,Connected with cooling fan 220V / 380V (depending on the user, generally 380V) 3,When the external cooling fan is DC 24V, this interface is a switch that controls the 24V fan to work or stop. The two ends of the interface are actually the normally closed contact points of the relay output on the motherboard. 4,Dual AC 24V power supply (choose 4 or 5 when making half bridge) 5,Dual AC 24V power supply (choose 4 or 5 when making half bridge) 6,Single AC 16V power supply 7,Power indicator (red) 8,Work indicator light, flashing during standby, and always on (green) during work 9,External indicator light, led to the LED interface outside the chassis 10,The soft start interface is connected to the R / s interface outside the chassis (can be set to open or close work through F-20, factory default close work, open stop status 11,Finely adjust the power potentiometer. When there is a large deviation in power, this potentiometer can be adjusted appropriately. 12,32-bit high-speed DSP processor 13,Externally connected programmable operating display 14,Isolated RS485 communication interface 15,External load temperature detection interface 1, with accuracy of ± 1 ° C (maximum 150 ° C) single channel, default 1 is used to measure external working temperature 16,External load temperature detection interface 2, with accuracy of ± 1 ° C (maximum 150 ° C) 17,Multi-function input interface (set by F-20) (1)10K input for external connection potentiometer, can adjust the power range from 20% to 100% (2)Externally connected PID input (0 ~ 5V) input Do infrared thermometer or thermocouple conversion voltage 0 ~ 5V input to achieve the display temperature and control power size (up to 1000ºC can be measured and displayed) 18,Connect the high-frequency Mutual inductor and pay attention to the direction. If the direction is reversed, the power is very small 19,IGBT module drive (when doing half bridge, choose 19, 20 or 23, 24) 20,IGBT module drive (when doing half bridge, choose 19, 20 or 23, 24) 21,Connected to high voltage DC bus 22,IGBT temperature sensor interface 23,IGBT module drive (when doing half bridge, choose 19, 20 or 23, 24) 24,IGBT module drive (when doing half bridge, choose 19, 20 or 23, 24) 25,Connected to high voltage DC bus 26,RS485 communication interface, connect A ,B 27,Externally connected K-type thermocouple 28,Externally connected 12V relay drives other required loads, synchronized with the fan start / stop of the machine
