Abstract
A heater bundle includes a plurality of heater assemblies, at least one of the heater assemblies including a plurality of heater units, at least one of the heater units defining at least one independently controlled heating zone. A thermal provision is configured to modify a thermal conductance along a length of the at least one heater assembly to compensate for non-uniform temperatures within at least one heater unit. The heater bundle includes a power supply device including a controller configured to modulate power to the independently controlled heating zone through the power conductors based on the determined temperature to provide a desired power output along a length of at least one heater assembly.
