5000W heater main board parameters

A/  5KW induction heater wiring instructions

1. The five indicator lights are power, frequency, current, voltage, and temperature of the IGBT movement.
2. The four touch keys are up, down, left and right, adjust the power up and down, and switch the display left and right
3. The 220V power supply is connected to the column "connected to 220V power supply", and it can be connected at will regardless of the neutral line of the live wire.
4. The coil is connected to the two terminals "connected to both ends of the coil", and the screws should be tightened.
5. The heater has a power-off protection memory function, and the shop will automatically return to the original working state when the power is turned off and the shop is reopened.
6. The board is factory set to supply power to work. At this time, there is a short circuit (black) in the "switch control" socket port to short-circuit this socket. You can also gently remove the short-circuit wire (black) on the "switch control" socket by hand, plug one end of a two-core cable into the "switch control" socket, and connect the other two plugs to the thermostat The normally open two contacts are connected and ready for testing. Or it can be switched with 0~18V DC power supply. But please confirm with the salesperson which mode to use before shipping! Factory settings.

B/  Instructions and notifications for 5KW electromagnetic heating control board

1, Requirement for the shell:
The main control board should be installed inside the shell since the controller carries high pressure and large current electronics are used. Then it is connected to heating coils, power and thermostat controller by insulation wire. This can prevent electric shock even if electric parts are touched. Also, since the board will generate heat, the shell should be designed to be easy for ventilation and thermal dissipation.
  A DC12 fan is also added to the device. Please secure the fans on two fixed column on the board and plug the fan into FAN12V two-pin socket next to the relay.
2. Since we only provide control boards, so you need to add other components such as heating coils. Choosing coils can vary depending on power. 10 sqm insulation high temperature resistance wire is fit for 5kw control board.
Coils are generally circular with capacity of inductance(L) 80±10uH (Measured by Victor's BICTOR6243 inductometer when coil is wound on the cylinder)
Note: circular coils usually wind 23 laps, which can vary depending on the diameter of the cylinder.
3, Winding of heating coil: Wind the coils according to user's specific requirements. Make sure the winding direction should be the same to with the parameter in one single ferric cylinder. Distance between each section of coils should be more than 60mm.
4, Requirement for the distance between heating coils and heated metal: The distance from the surface of the coils to the surface of the heated metal should be adjusted according to diameter of coils. The larger diameter of cylinder, the shorter distance is needed. On the contrary, the smaller diameter of cylinder, the further distance is needed. In the case of 5KW control board, 15-22mm is most suitable because the controller will deteriorate when it is too close, causing heat and even damaging IGBT while power could be gradually degraded when it is too far, causing adjustment failure due to over-voltage protection circuit.
5. The controller can work either by directly inputting power or being controlled by the thermostat controller.
a, Directly connecting to power
Connect the 220V power supply to the L and N wire of the control board through an insulated wire. Connect the post of lead lines of the coils to the terminal of the controller (Make sure if it is firmly contacted). This board has been set to work once there is power supply.
b, Using thermostat controller
Connect the 220V power to the L and N wire of the control board through an insulated wire. Connect the post of lead lines of the coils to the terminal of the controller (Make sure it is firmly contacted). Gently remove the black short-circuit line on the socket, then attach one end a connecting lead (two-wire cord with a 2-pin plug at each end) to the socket of the soft switch and the other end to the two contacts of therrmostat controller. Test the machine.
Note: The thermostat is not allowed to contact with the mains or other high-voltage.
c. Combination of control boards
If you need one thermostat to simultaneously control the switches of several boards, first pick a main control board, and then use the connecting line (two-wire cord with a 2-pin plug at each end) to  connect the "sub-panel control" of the main board to the "voltage control" of another board. Repeat the above steps if you want to add more boards

C/  The advantage of electromagnetic heating control panel in the heating system of plastic machine

Let's take injection molding machine for example to illustrate the advantages of electromagnetic control panel. Induction heating can not only replace traditional resistance heating wire but also outperform it in many ways.
1, Saving electricity and avoiding rising the temperature of surrounding.
Currently, heating coils, which passes heat to cylinder through contact conduction, is most widely used. Yet there is huge heat conduction loss during the process because only the heat close to the surface in inner side of the cylinder is effective while most of the exterior heat has been dispersed into the air, leading room temperature to rise. In addition, the resistance wire heating has a low power density, which means it is not adaptable in situations where high temperature is in need. In contrast, induction heating heats the metal cylinder itself while additional thermal insulation material can be wrapped on the barrel at the same time. It greatly reduces heat loss and improves the thermal efficiency, saving up to 30% ~ 50%% electricity. It proves very effective for injection molding machine which requires high power.
2, Rapid heating, accurate control of temperature in real-time.
The heat is generated by the metal cylinder itself in electromagnetic field so the internal and external temperature stay the same. In this way, quality and productivity have been greatly improved.
3, Long working life and simple maintenance.
Traditional method uses heating resistance wire whose service life decreases as it is exposed to high temperature and harsh environment that causes oxidation in the device. In comparison, in the case of induction heating, the coil itself doesn't heat up but wound up by insulation material and high temperature resistance wire. Therefore, there is longer service life and free of troublesome maintenance.
4, High power. With the development of electromagnetic technology, the production process and techniques of electronic parts have improved. So far, software can provide stable voltage protection up to 1.5-35KW. 
5, Safe and reliable. Induction heating can cool down the surface temperature of the machine, which is completely safe to touch. This means that traditional accidents such as burn and scald can be avoided, thus the safety of workers can be guaranteed. In addition, electromagnetic radiation equals to only 1 percent of that of a phone, so there is no harm done on human body.
