Based on 32-bit DSP all-digital processor, half-bridge series resonance;

Using highly reliable digital phase-locked loop control technology, digital stepless adjustment, the power can be set through the digital display, and can also be adjusted by external potentiometer, and it is also compatible with 0~5VDC or 4~20mA analog PID to control the power output, and the power is 20%~100% adjustable;

It has a completely electrically isolated soft start control interface (short circuit start/disconnect stop), which is easy to connect with the thermostat, and there is also a 12V/24V input start/stop mode control interface, which is convenient to connect with various solid state relays (there is a voltage input to work, on the contrary, stop heating, when using this function, the soft start interface will be empty, and the short circuit ring needs to be removed), the control response speed is fast, and the start time is <1S;

It has the protection functions of heating coil short circuit and open circuit, 130% overload and no-load instantaneous protection function, and the protection response time ≤2uS;

The coil has wide compatibility and can be compatible with the same model products of other companies;

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;

With the open application platform, users can automatically read important parameters such as current, frequency, phase difference, temperature and so on with our company's special digital programming display, and can also set various application parameters as needed, making installation and debugging more simple and convenient;

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;

Built-in modbus RTU communication protocol, with 485 interface, can be external contact touch screen, can also easily achieve remote control;

Industrial-grade components, 100% tested by high temperature aging, to ensure long-term continuous and reliable work in 50°C industrial environment for 24 hours, average trouble-free service life: ≥50000Hrs;

Factory standard configuration: integrated control board radiator, 1 external industrial indicator light;

The physical size of the control board: length 220mm * width * height, customers must be equipped with a cooling fan (/220V)165mm90mm150mm

The advantages of the company's electromagnetic heating plate

The power supply adopts a wide voltage design, 210V~260V constant power output, especially suitable for the occasion of large grid voltage fluctuations

It adopts 4 original imported IGBT half-bridge series resonant structure, the product quality is more stable, the anti-interference ability is stronger, and the continuous work for a long time does not burn the plate

The power can be set by the digital display, and it 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

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;

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;

Add 12V/24V voltage control interface, which is convenient for SSR solid state relay control;

National unified warranty for 1 year, product lifetime maintenance, full technical guidance and service, so that you have no worries;

System wiring description and schematic diagram

2 indicators, 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;

Soft Boot This terminal is used to start/stop. It works when it is closed, and stops when it 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;

AC-L and AC-N are 220V power inputs, and OUT1 and OUT2 are output terminals connected to heating coils.

When installing, it should be noted that the radiator is live, do not touch the shell, and the shell must be reliably grounded;

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 6mm² inductance is 80~100uH, about 15~17m (excluding lead length), the thickness of the insulation cotton is required to be about: tubular coil 15~, flat coil: 10~15mm, quota working current: 14~16A, frequency: 10K~20KHZ.25mm
