ICT100 INDUCTION COOKER Product features 1. Pollution free：No burning, no smoke and detrimental gases like carbon monoxide and sulfide. 2. Safety: no flame, no exhaust gas. 3. Cleanliness: high rigidity ceramic faceplate, easy to clean. 4. Energy saving: thermal efficiency ≥85%, saves your energy. 5. Micro-computer control function is more convenience. 6. Heating power selection. 7. Automatic cooking stop when pot or pan is removed. 8. Overheat protection. Safety functions and features 1. High current protection. 2. Auto shut-off. Unit automatically turns off if no buttons are pressed for two hours. 3. When the voltage rises over 140V or drops to less that 90V, the nixie light will display error codes. Once the voltage return to normal, the unit will automatically operate. 4. Pot detection. Turns off after 1 minute if pot is not compatible. 5. Pot sensor for short/ broken circuit protection. 6. Dry-pot protection. Pot sensor prevents the unit from burning pots without water, which can cause the pot to overheat. Unit automatically turns off when pot exceeds temperature limit. 7. Built-in surge protection. 8. When the unit is off, the fan may continue running more 1 minute. Function 1．Operation and working mode （1） Stand by state：When connect power, the display and the indicated lights don’t work, the unit is in the stand by state, no power output, the fan is automatic. It doesn’t work if press other keystroke other than “ON/OFF”. （2）Working state：When in stand by state, press “ON/OFF”，the LOW LED will on，7 segment LED show "00"; press “+ or -” to adjust the power，press “∧ or ”∨ to adjust the time, press “ ∧ or ”∨ for 2 seconds, the digit will rise up continuously，press “ON/OFF”, the buzzer will ring, the unit will return to stand by state. If start the unit without putting the pan or remove the pan in the middle time, the buzzer will ring to detect the pan, the unit will turn off after 6 seconds. Using your induction cooker 1. When in the course of the working state, if do not set the time, the display will show “00”, it doesn’t work when press “”∨ at this moment, if press “ ”∧ each time, the digit will rise up by 1. If press “”∧ for 2 seconds, the digit will rise up continuously until reach “99”. If pause pressing “”∧ in the midway, the digit will stop rising up, and the time when it stop is the setting time. 2. Timer: when in the course of the working state, if set the time, it will work as per the time. If press “ or ”∧∨ in the midway, the setting time will move down or up. When 1 minute left for the count down time, the display will show second as the count down time. When 3 seconds left for the count down time, it will ring for 3 times, and then continue heating. The display show “00”. 3.When press the keystroke which is efficient, the buzzer will have a short ring. If turn off the unit or set the time or happen malfunction, the buzzer will have a long ring. 1.

1. Theorem of IH heating Induction cooktop is an appliance which transforms electromagnetic induction to be a heating power. By the rectifier circuit, induction cooktop transforms A. C. voltage to be D. C. voltage and change D. C. voltage to be a 20-40 KHz high frequency voltage through the control circuit. This high speed changes of voltage passes the coil will occur a high speed changing magnetic field. The magnetic force occur numerous swirls when it passes though ferromagnetic cookware and heating up the cookware for cooking. 1. Circuit diagram of Induction cooktop Main power Sub-Power Main circuit IGBT drive circuit Synchronize circuit Oscillation checking circuit Trigger circuit Pulse checking PWM (Pulse Width Modulation) VCE Viktron Circuit Express checking/circuit protection Surge voltage checking/circuit protection Power voltage checking circuit Electric current checking circuit IGBT temp checking Under-pot temp checking Alert circuit Cooling system Display/ button control C P U Magnetic force Coil Holding plate Turbulent Pot 2. Working process： CPU provides the signal to IGBT and IGBT on. CPU will decide to let IGBT keep working by the Pulse circuit checking. If IGBT is working, the circuit system includes Main Circuit, Synchronize Circuit, Oscillation Checking Circuit, IGBT Drive Circuit will automatically control pass through or stop of IGBT. Power voltage checking circuit and Electric current checking circuit will check with the voltage and electric current. And PWM Pulse Width Modulation will control the time of IGBT should get across. Then CPU will control the power output of whole system. VCE Viktron Circuit Express checking/circuit protection, Surge voltage checking/circuit protection, IGBT temperature checking, Under-pot temp checking are the ambient system to protect the whole system and working in normal. IGBT will automatically turn off if any error is detected by the ambient system. Then Alert Circuit will display the relevant information of the error. Cooling system is providing a normal working temperature for the system.
