XK-DJ201 Power Electronics And Motor Speed Regulation Training device 

XK-DJ201 type power electronics and motor speed regulation training device is widely used for all kinds of motor speed regulation and part power electronics experiment in all kinds of secondary specialized colleges and vocational colleges.

System characteristics
  1 Modular structure
      (1)Adopt modular structure, each experimental hanging box can finish the experiment independently and the hanging box also can be combined differently according to demands of different experiment which make a greatly rising degree of combination.
   2 High reliability and safety
       (1)High voltage module wholly adopt insulation of K4 jack and high voltage insulation plug wire and thus guaranteed the high safety coefficient when users doing experiment.
      (2)All high voltage circuit is equipped with over-current fuse and low voltage circuit adopt self-recovering assurance. These can effectively prevent short-circuit and burning a component caused by users’ faulty connections under the circumstances that have ensured the users’ safety and circuit reliability.

Applications:
    (1)Adopt the most popular technology at present, use great power of IGBT, can finish  the speed regulation experiment of most typical kinds of motors and part of motor drive experiment
    (2)Through detaching and combining the core part of the speed regulation, make the experiment table can finish the experiment except the motor part experiment, also it could apply to teaching and learning of power electronics ,analog electronics and single-chip computer.
4 High technical progressiveness
   (1)The experimental table adopt the control method accordance with the main trend inverter at present. the core part of the inverter is apparently showed at the experimental table and thus make users understand the converter’s technique and process effortlessly.
  (2)The core control part of experimental table adopt DSP which is a progressive algorithm and ensured the accuracy and velocity.
