To achieve high stability temperature control
Standard control / heating, cooling control.
The device used for the temperature control of the temperature control of the extrusion molding machine can prevent over heating and cooling.
According to the object device can choose any one of the following control method.
Standard control (heating or cooling).
Heating, cooling control (heating and cooling).
Hybrid control (combination of standard control and heating, cooling control).
To reduce operating costs by saving energy
Peak current suppression
After the peak current suppression function is used, the number of the upper limit output limit of each channel can be changed automatically,
Split transistor output time. To suppress the peak current.
Restrain the peak current to achieve energy saving effect (reducing the power supply capacity of the equipment, saving the electricity contract), and reduce the operation cost LD77MS4 PDF datasheet.
Achieve average temperature control
Warming function at the same time
By making the arrival time of the multi loop consistent, uniform temperature control function.
It can control temperature uniiform, to ensure that the control object no local burning or thermal expansion LD77MS4 PDF datasheet.
No idle running, with energy saving effect, can reduce operating costs.
