2. Advantages of our company's electromagnetic heating plate
1. The power supply adopts wide voltage design, 210V～260V constant power output, especially suitable for occasions where the grid voltage fluctuates greatly;
2. Using double 60A imported IGBT (G60N120D) half-bridge series resonance 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 board;
3. Increase PID interface control function, 0～5VDC control power output, making heating temperature control more accurate, and more suitable for production matching of various heating equipment;
4. Add 12V and 24V voltage control interface to facilitate the control and use of solid state relays;
5. Leading to Japanese advanced technology, the product undergoes strict functional test and aging test before leaving the factory, and the quality is effectively guaranteed. The repair rate in 2010 was 2.8%;
6. The nationwide unified warranty is 1 year, and the product has lifetime service, so you have no worries!
Three, control board wiring description and schematic diagram
1. Three indicator lights, power indicator light and working light (two working lights, one on the board, one external), which are on during normal operation, and the working light is shining when the transmission circuit fails or does not work;
2. Soft Boot This terminal is used to start/stop. It works when it is closed; it stops when it is open.
Note: The Soft Boot terminal is closed by default at the factory. When using soft start interface control, the closing jumper must be removed.
3. AC-L and AC-N are 220V power input;
4. OUT1 and OUT2 are connected to heating coils;
5. When installing, please note that the radiator is live! Do not touch the shell or short-circuit to ground;
6. Coil reference parameters: Mica-wrapped glass fiber braided high temperature resistant cable, cross section 6mm2, inductance is 80-100uH, about 10-12m, insulation cotton thickness is about 15-20mm, rated working current: 14-16A, frequency For: 16K～20KHZ.
