  1. INDUKČNÍ VARNÁ DESKA

  2. ANALOGY WITH THE TRANSFORMER DeschaJ: Stacking up of iron strip = empilement de lames de metal

  3. THE SKIN EFFECT Principle In a wire In the pan Resulting current Bottom of the pan Density of current Thickness of the pan

  4. Gas Cast iron Radiant Halogen Induction 10 20 30 40 50 60 70 80 90% EFFICIENCY comparative rate It results significant energy savings

  5. QUICKNESS OF HEAT RADIANTHALOGEN GAS CAST IRON INDUCTION Time required to bring 2 litres of water from 20°C to 95°C

  6. QUICKNESS OF COOLING RADIANTHALOGEN GAS CAST IRON INDUCTION Decreasing to 60°C after boiling 2 litres of water

  7. THE PANS If you choose a pan with this logo, you will be certain that it is absolutely compatible with your induction hob under normal condition of use • The compatible induction pans must be made of a magnetic material : • Enamelled steel pans with or without non-stick coating • In cast iron with or without enamel coating • In ferrous stainless steel – laminated stainless steel • In aluminium with special bottom We advise to choose pans with a thick bottom and a minimum diameter of 12 cm (i.e. 5 inches) for even more cooking : the heat spreads more evenly

  8. ZABUDOVÁNÍ Fixing supplied with the hob SEAL

  9. FITTING ABOVE A UNIT WITH A DOOR OR A DRAWER 1- In case of a small cross piece, there is no problem 2- In case of a rectangular cross piece or with a closed top, make a bevelled cut so that air comes out of the hob 3- In case of an intensive using with more than 1 cooking zone, we advise to make an opening on both sides of the unit

  10. FITTING ABOVE AN OVEN Oven in lower position Oven in upper position Other brand of oven Same brand of oven

  11. FITTING ABOVE A DISHWASHER The top of the dishwasher must be covered with an insulation plate (77X7781). Ensure that there is a minimum opening of cool air.

  15. MAIN COMPONENTS

  16. SYNOPTIC OF A GENERATOR Main power Filter 5 and 12V= power Command level Rectifier keyboard Inverter 25 to 50Khz Pilot of inverter Inductors

  17. THE KEYBOARDSwith capacitive keys IX2, IX3, IX3WR and IX4000 High frequency signal

  18. THE CURRENT FILTER • Protections against over-current due to the work of the hob • Stop the outside and inside interferences • Stop the outside over current

  19. THE FILTER IX3 and IX3WR Earth screw Fuse tracks Direct live Live wire Neutral via the relay Neutral Direct neutral Command Relay 15V= Supply of the fan Power relay

  20. THE RECTIFIER Filter rectifier After rectifier Before rectifier Filter rectifier • Bialternation rectifier by diode bridge • Filtering of high frequencies by condenser Outside current 310 V= when hob doesn’t work

  21. THE TRANSISTOR INVERTER V/2 Inductor Rectified current V V/2 • 2 power transistors • 2 condenser • 2 diodes

  24. GENERATOR TRIPLE CROWN INDUCTOR or • 3 coils • Pan diameter from 12 to 26 cm • Only fitted on IX3WR • Power from 50 to 2800W • ‘Booster’ 3200W

  25. GENERATOR « KRÔNE » INDUCTOR • 2 coils • Pan diameter from 12 to 32 cm • fitted on IX3, IX3WR and IX4000 • Power from 50 to 2800W • ‘Booster’ 3600W

  26. 230V~ GENERATION IX3 Earth screw, required when hob is working • Repartition by 2 relay • 3 cards • Manufactured since 1996 Supply of the fan Relay of répartition Bipolar transistors Rear CTN Front CTN diode bridge Plug in keyboard

  27. IX3 Possible configurations

  28. 230V~ IX3WR GENERATION Filter card Earth screw, required when hob is working • Share-out through transistors • 3 cards • 3 crown cooking zones • Manufactured since 2000 Supply of the fan 3 crowns cooking zone relay supplying Transistors Diodes bridge Rear CTN Front CTN Transistors Plug in keyboard

  29. IX3WR

  30. IX4000 GENERATION • Share-out with 1 relay • 2 cards • Start of manufacturing 09/2002 • Replace gradually IX3
