1.Overview
The DLWD-JZL031 AC and DC drive training system consists of 4 areas: system power supply part, AC speed control part, DC speed control part, and instrument measurement part. The components required for the experiment are all embedded on the panel, and all the wiring is led to the K4/K3 type safety terminal on the front panel, and the experiment is connected by sheathed test line.
DLDS-JZL031 AC-DC Transmission Training System is developed according to the requirements of teaching materials such as “Automatic Control System of Electric Drive”, “DC Speed Regulation”, “AC Frequency Conversion Speed Regulation”, “Senior Maintenance Electrician” and other teaching materials, and is suitable for Motor and drive-related professional courses in colleges and vocational colleges. The AC DC speed control experimental device mainly trains and assesses the parameter setting and system application ability of the AC frequency converter and DC speed control device, as well as the programming ability of some programmable logic control.
System function
-The equipment frame is used to carry the entire training equipment
