COMPONENTS
Designation Function Features
Triple-crown inducer
The cooking zone recognises and fits
automatically the diameter of the
container, 12 to 26 cm diameter, so as to:
• Deliver the optimum power
corresponding to the container.
• Give excellent heat distribution.
• Provide a consistent cooking
temperature
Inducer composed of 3 windings
• Diameter 1 : 6 cm
• Diameter 2 : 10 cm
• Diameter 3 : 22 cm
• Pmax : 2800W
• Booster : 3200W
• Tables : IX3WR, IX6
This source implies the use of a specific
relay installed on the IX3WR power board.
The generator always supplies two coils
at a time but unlike the Krône source,
there is no sequenced distribution
between inside and outside: the board
detects the presence or absence of a
large-diameter source and defines its
operating mode.
Fan
Ensure cooling of electronic components
located in the hob.
Please note:
The fan voltage changes
according to the temperature of the power
board (measure by NTC probe).
8V for 60°C
10V for 70°C
12V for 80°C
The temperature read by the NTC is not
the temperature inside the cabinet but the
copper temperature.
Each generation of hobs is characterized
by a different fan:
• IX1 : Tangential to 12VDC
• IX2 : 12VDC
• IX3,IX3WR : 230VAC, 23W, 270Ω
• IX4000, IX6: 12VDC (PC type)
Power board

The power board is used to manage the
majority of the functions
- Rectification
- Low-voltage power supply
- Power supply to high-frequency inducers
- Checks, using a microprocessor
The power supply frequency varies
between 25kHz at maximum power and
50 kHz at 500W.
The regulation between 50 and 500W is
obtained by clipping the power supply.
A power board is used to supply 2
sources or a double source.
For this purpose, two features exist:
• one uses a single inverter with
front/rear distribution relay (IX 1, 2, 3
and IX4000)
•
the other uses one inverter per
source (IX3 WR)
Note: Hob IX1 is composed of a power
board and a separate control board.
