10. Strong anti-interference ability, 30 controllers can be controlled to start/stop at the same time on the same heating body without interfering with each other;
11. With the open application platform, users can automatically read important parameters such as current, frequency, phase difference, temperature and so on with our special digital programming display, and can also set various application parameters as needed,making installation and debugging more simple and convenient
12. You can set 1~255 days of working time, automatically lock after the timer is completed, you need to enter the password to restart, and you can also set 6 groups of timing on/off according to your needs;
13. Built-in modbus RTU communication protocol, with 485 interface, can be external contact touch screen, can also easily achieve remote control;
14. Using industrial-grade components, 100% of them have been tested by high temperature aging, to ensure 24 hours of continuous and reliable work in the industrial environment of 50°C for a long time, and the average trouble-free service life:≥50000Hrs;
15. Factory standard configuration: integrated control board radiator, 1 external industrial indicator light;
16. Physical size: length 220mm * width * height, customers must be equipped with a cooling fan (/220V);165mm90mm150mm

The advantages of the company's electromagnetic heating plate

1. The power supply adopts a wide voltage design, with a constant power output of 210V~260V, which is especially suitable for the occasion of large grid voltage fluctuations;
2. It adopts 4 60A original imported IGBT half-bridge series resonant structure, the product quality is more stable, the anti-interference ability is stronger, and the board is not burned for a long time continuous work;
3. The power can be set by the digital display, and can also be adjusted by an external potentiometer, and it is also compatible with 0~5VDC or 4~20mA analog PID to control the power output, so that the heating temperature control is more accurate, and it is more suitable for the production of various heating equipment;
4. The working time can be set for password locking, which can effectively prevent the problem of difficult collection of project funds, and can also set 6 groups of timed on/off according to the need, which is more intelligent and more convenient to use in areas with peak and valley electricity prices;
5. It comes with 485 interface, which can be touched externally, and can also be easily controlled and centralized, which is conducive to the secondary development of equipment and the comprehensive management of the factory;
6. Add 12V/24V voltage control interface, which is convenient for SSR solid state relay control;
7. The national unified warranty is 1 year, the product is maintained for life, and the whole process of technical guidance and service allows you to have no worries.

System wiring description and schematic diagram

1. Twoindicators, red power indicator and green working indicator (external work indicator), Power and Work are lit at the same time when working normally, the working indicator is flashing when the heat preservation state is shining, and the working indicator light flashes quickly when the fault state is shining;
2. Soft Boot This terminal is used to start/stop. It works when it is closed, and stops when is disconnected.

Note: There is a short-circuit piece on the socket next to the green socket (Soft Boot terminal) at the factory, the socket has the same function as the green socket, if the green socket is used for control, the short-circuit piece must be removed, if the short-circuit piece is not removed, the control board will be automatically started when it is powered on;

3. AC-L and AC-N are 220V power inputs, and OUT1 and OUT2 are output terminals connected to heating coils.
4. When installing, it should be noted that the radiator is live, do not touch the shell, and the shell must be reliably grounded;
5. Coil reference parameters: (Please refer to the comparison table below for details).

Mica winding glass fiber braided high-temperature resistant cable, cross-section national standard 8~10mm² inductance is 60~80uH, about 12~15m in length (excluding lead length), the thickness of the insulation cotton is required to be about: tubular coil 15~, flat coil: 10~15mm, quota working current: 20~, frequency: 10K~20KHZ.25mm22A
