Abstract (en)
A system includes a heater bundle having at least one heater assembly (18) with a plurality of heater units. At least one of the heater units (52) defines at least one independently controlled heating zone, and a plurality of power conductors are electrically connected to the heater units. A power supply device (14) includes a controller (15) configured to modulate power to the at least one independently controlled heating zone through the power conductors, and the controller (15) is configured to calculate temperature within the at least one heater unit based on a predefined model and at least one input, and the controller (15) modulates power to the at least one heater unit based on the calculated temperature.
