    摘要： A heater system (10) includes a heater bundle. The heater bundle includes at least one heater assembly, where the heater assembly includes a plurality of heater units (52), and more than one of the heater units (52) defines at least one independently controlled heating zone. The heater bundle includes a plurality of power conductors (56) electrically connected to the independently controlled heating zone. The heater system (10) includes means for determining temperature and at least one power switch (120), the power switch (120) disposed proximate the heater bundle. The heater system (10) includes at least one controller (15) configured to modulate power to the independently controlled heating zones (62) through the power conductors (56) based on the determined temperature to provide a desired power output along a length of the heater assembly. The controller is configured to provide power to the power switch (120).

    摘要： A heater system (10) includes a heater bundle (12) with heater assemblies (18), at least one of the heater assemblies (18) having a plurality of heater units, at least one heater unit having an independently controlled heating zone, and the at least one heater assembly (18) having a physical construction configured to deliver a variable power output per unit length along a length of the at least one heater assembly (18). A plurality of power conductors are electrically connected to the plurality of heater units and the heater system (10) further includes a means for determining temperature. A power supply device (14) includes a controller (15) 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 the at least one heater assembly (18).
