MR281E Analogue Electronics Experiment Kit Teaching Equipment Electronics Trainer
Product Introduction:
Analog circuit experiment box make all the experiment module concentrated distributed on the circuit board, lead out the down-lead through the locking type jack, student can set up circuit by themselves according to experiment project, it can cultivate the ability of thought and start work, it also enhance the applicability of this experiment box. Analog circuit experiment box is based on the teaching experiment of “ higher technical school fundamentals of electronic technology basic requirements of the course teaching” including all the experiment content of “ basis of analogue electronic technique” it is the last type experiment machine for the electronic technique, electronic circuit and other course of institutions of higher education, secondary specialized school and TVET university.
Experiment box content
1. Power supply: input: AC 220V±10%,50HZ

Main characteristic
The experiment board front side of this experiment box adapt imported wrinkle varnish, with principle diagram and symbols. It is equipped with corresponding component, it can make the student increase the perceptual knowledge, the portion installed on locking connector which need measuring and observation, easy to operation, reliable, maintenance-free, simple and direct.
Experiment circuit adapt unit circuit type design, each unit circuit based on the basic circuit, then connect to different component as circuit parameter, or according to different unit circuit combination, it can complete different experiment requirement. This experiment box is made up by integrated aluminium alloy profile, elegant colour and modelling, box fastness and reliable, no deformation, light weight, good insulation and safety performance, easy to open and close the case cover, nice exterior.
