• Power supply: three-phase 5 wire system, 380V (± 10%), 60Hz, single-phase control voltage 220V
• The operating system of the whole machine adopts PLC modular control, 
• which can be controlled by single action or linkage speed regulation. It can be operated visually through the 10.1-inch touch screen.
• Communication control is adopted between PLC and frequency converter, which has higher precision and faster response than analog speed regulation; At the same time, PLC is equipped with Ethernet interface, and users can monitor remotely.
• The whole machine is a dual control system: analog speed regulation and manual self reset knob speed regulation are set on the touch screen. The parameters can be set and adjusted freely through the touch screen or controlled by self reset knob speed regulation.
• The extruder host and traction motor are made of high-quality brand AC motor, controlled by frequency conversion speed regulation system, and the latest generation of intelligent electronic display calculus temperature controller is selected for temperature control instrument, with temperature control accuracy of ± 2 ℃.
• The panel is equipped with various instruments, indicators, switches and other necessary components, with complete protection functions such as overload, overheating and overcurrent,
• The low-voltage components of the whole machine adopt internation top brands (Chint or Schneider), which has the advantages of stable starting, running and stopping of the production line, energy saving and consumption reduction.
• The control box is spliced by high-quality anodized aluminum profile and aluminum die-casting corner parts, with simple and stable appearance and simple operation. The dust filter device is installed in the main control box to prevent the service life of electrical components in the cabinet from being affected by dust.
