A plurality of individually corresponding heaters and temperature sensors are provided along with a plurality of a PID control means. An average temperature/gradient temperature calculating means calculates the average temperatures of the temperatures measured by the temperature sensors and the gradient temperatures based on the measured temperatures. Each of the PID control means outputs an operation signal so that the average temperatures or gradient temperatures may be made equal to the desired values. A distributing means distributes the operation signal from each of the PID control means to each heater so that control by the PID control means may produce no effect on the control of the other PID control means.

Controller, temperature regulator and heat treatment apparatus

A power source apparatus with a saving in wiring, large noise immunity and an additional function is achieved by connecting AC input bus lines (Vin+), (Vin&#x2212;), DC output bus lines (Vo+), (Vo&#x2212;) and a current balance signal bus line (CB) for connecting first, second, third power source unitsthrough connectors to form a module power source and connecting an additional function unitfor adding a predetermined additional function to the module power source using the bus lines to this module power source through a connector.

Power source apparatus

A power supply module includes a plurality of power supply modules. One of the power supply units is designated as a master power supply unit. Other power supply units are handled as expansion power supply units. The power supply modules can be connected in parallel on a DIN rail so that the master power supply unit may supply an external AC voltage to the expansion power supply units. When a desired power supply capacity exceeds a power supply capacity of the master power supply unit, an expansion power supply unit is connected in parallel with the master power supply unit in order to increase the power supply capacity.
