Automatic identification of load and phase-locked function, In order to get the highest power factor at the load end and make the circuit precisely controlled in the weak inductive area, the circuit can work efficiently 11. Several electromagnetic heating controllers are installed in parallel on the same heating tube, which does not interfere with each other 12. The power saving effect is good: compared with the current electric heating coil, the electric heating coil has the advantages of high efficiency and high efficiency, Power saving can reach more than 30% 13, easy to install: can be connected to barrel type and flat plate type induction coil 14, low Cold Sparkler Fountain operation cost, less maintenance, product warranty for 1 year, Lifetime maintenance 3. Load characteristics of the products: 5130 steel and 45 steel, the distance between coil and workpiece 2.5cm (special materials need special debugging) parameter requirements of half bridge serial number power (kw) input current (a) inductance with load (Uh) coil current (a) national standard of line cross section (mm2) effective length (m) 3M side lead on both sides thickness of insulation cotton (mm) 5 7-8 25 0-300 20-30 6 45-55 20 2 8 11-12 200-250 25-35 8-10 35-45 20 note: inductance is only one of the applicationsThe working frequency and current should be measured, and the power can be matched by increasing or decreasing the number Electric Cooking Stove Manufacturer of coil turns. The inductance with high heating temperature requirements should be appropriately reduced. The working frequency should be in the range of 11-28khz, and the frequency should not be lower than 11khz when heating to the required maximum temperature (equivalent series impedance r will rise when the workpiece temperature rises, and the resonance frequency of RLC will decrease, In the same way, it is normal for the current to decrease when R rises and the bus voltage remains unchanged) 4. The working state of electromagnetic heating controller is in order to facilitate operation, all function keys are unified (can also be customized according to the customer's demand) 1. Power on standby: the power indicator on the control board is on. 2 Power on and standby: the fan runs for one minute 3. Display the digital screen to check the temperature under standby, input voltage working state under startup 1. Power indicator on the control board is on. 2. The fan is running all the time 3. Display the digital screen to view the temperature, input voltage, input current, working frequency, working gear, working state 5 The four buttons on the panel are "", "function key", "+", and "confirm key". (Note: PID and common control modes only have "function key") 1. "Function key": there are seven kinds of indication, such as "gear", "power", "frequency", "voltage", "current", "IGBT temperature" and "resonance state". There are eight gears in "gear". The highest power in "8" gear is equal to the lowest power in "1" gear. The adjustment of the gear is controlled byThe "+" and "-" keys are completed. "Power" display head letter is "P", indicating the apparent power. The "frequency" display head letter is "F", indicating the size of the current running frequency. "Voltage" display head letter is "U", indicating the size of the input voltage. "Current" display head letter is "a", indicating the input current size. "Temperature" display head letter is "C", indicating the current IGBT temperature. "Resonance state" has two kinds of display: "pass" means that the system has found the resonance point or is in the resonance state, which is normal "E8" is a warning state, which means that the resonance point has not been found, and the system is in the state of deviation from resonance. Therefore, the inductance of the load should be adjusted (usually the inductance should be increased), so that the system can reach the normal "pass" state by adjusting the load inductance. And check whether the input current is in the corresponding maximum power 2, "+" key: only when it is displayed in the "gear" state, pressing this key is effective; when the current is the top gear "8", pressing this key does not work. 3. "-" key: only when the "gear" status is displayed, pressing this key is effective. When the current gear is the lowest gear "1", pressing this key does not work. 6、 The failure code displayed by the digital tube of the electromagnetic heater: "- E2 -": overvoltage protection (higher than 430v); "- E3 -": under voltage protection (lower than 310V); "- E4 -": overheating protection (IGBT is higher than 75 ° C, and the temperature of IGBT drops to 60 ℃) "- E5 -": ultra low temperature protection (temperature resistance open circuit detection); "- E6 -": IGBT over-current protection; "- E7 -": output over-current protection; "- E8 -": input over-current protection. "- E9 -": no inductive coil fault protection. 7、 Main application fields: in the energy-saving transformation of industrial heating equipment such as plastic mechanical injection molding machine, granulator, film blowing machine, wire drawing machine, boiler, etc. note: the winding direction of multi group combination must be unified, and the spacing between each group of coils must be more than 100 mm. Note: 1. The main engine should be cleaned regularly, generally once every 2 months. Soft brush or high-pressure air gun can be used to remove dust to ensure a good ventilation environment inside the instrument. 2. If the use environment is corrosive gas, spray insulating varnish. Or use other insulating and anticorrosive materials. 3. The air temperature shall not be greater than 50 ℃. -The founder of the new electromagnetic heating controller adopts Infineon IGBT power devices imported from Germany and electromagnetic heating technology from Sweden. The advantages and characteristics of the electromagnetic heater are as follows: 1. Good energy saving effect: compared with the original resistance 2
