The advantages of the company's electromagnetic heating plate

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;

Adopting two 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;

It can be customized with 0~5VDC or 4~20mA analog PID control interface to control the power output, make the heating temperature control more accurate, and more suitable for the production of various heating equipment

Add 12V and 24V voltage control interfaces, which is convenient for solid state relay control;

The introduction of advanced production technology from Japan, the products have undergone strict functional tests and aging tests before leaving the factory, and the quality has been effectively guaranteed, and the repair rate in 2019 is 3.6‰;

1 year of national unified warranty, lifelong maintenance of products, full technical guidance and service, so that you have no worries!

System wiring description and schematic diagram

Three indicators, power indicator and work light (two work lights, one on the board, one external), power and work at the same time when working normally, when in the state of stop work or protection, the work indicator is flashing;

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, there is no need to connect the green socket, and the control board will be automatically started when it is powered on;

AC-L and AC-N are 220V power inputs;OUT1 and OUT2 are connected to the heating coil;

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 10~12m (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~, frequency: 15K~25KHZ.25mm16A

Single phase half bridge 3.5KW electromagnetic heating control board simulation version, imported technology and materials, more stable quality, stronger anti-interference ability
