KRJ - 6860E variable frequency technology and industrial electrical control devices Training
The device combines current colleges "electric drive", "Frequency Control Technology", and so on experimental program requirements, in particular applies to the institutions of the existing laboratory equipment upgrading. The device fully cultivate the actual practical ability of students to complete more engineering professional courses such as "electric drive", "variable frequency control technology" experiment, and expansion "PLC programmable technology" "DC motor" such courses experiment.
Main features:
1, the five-wire three-phase power input, the power switch control from leakage protection, a three-phase ceramic fuse.
2, the power control screen for exigency stop by the exigency stop button control.
3, the screen is equipped with a voltage leakage protection devices, or control screen if it has strong power output leakage phenomenon, and to cut off the power, indeed
Bao experimental process safety.  
4, Ping tops of a set of current leakage protection, control screen if leakage phenomenon, leakage current over a certain value, that is cut off
Power.
5, experimental use of closed cable sheathing structure, the use of safe, reliable, to prevent electrocutions.
Device configuration:
First, power control screen
And the three-phase 380 V single-phase 220 V AC power, providing the necessary experiments DC Power Supply (0-30 V/1.5A), automatic transmission and automatic protection and restoration of function, a current-mode and dual-voltage leakage protection.
Second, experimental tables
Experiment tables for steel and wood structure, desktop as fire, flood, wear resistant plate, solid structure, modeling aesthetic generous.
Three experimental components linked Box
