AF124E Training Bench For Selectivity Didactic Equipment Electrical Engineering Lab Equipment
Product overview
1.1 overview
This system can simulate selective training system, so that students have a primary intuitive understanding of industrial safety electricity. To cultivate the students' corresponding knowledge and skills, suitable for the teaching and skills training assessment of higher vocational colleges, vocational schools, secondary vocational schools and technical schools.
1.2 features
(1) training platform adopts aluminum frame type structure, measuring instrument and load module USES the way of hanging box installation, training power built-in integrated installation, each unit with flexible, easy to use, not easy to damage. The bottom is equipped with universal wheel, which can be moved flexibly.
(2) the experimental circuit and devices are fully configured and can be used in combination to complete the training contents of a variety of subjects.
(3) the training platform has a good security system.
1.3 performance parameters
(1) selective training platform device: all aluminum alloy structure, the shape size 600*600*1800mm (long width).
(2) rated voltage: 3 x 230 V / 400V; Frequency: 50 Hz; Security terminal: Ø 4 mm.
(3) power box unit: aluminum profile panel structure, power supply parts embedded installation, each module is installed on the aluminum alloy panel, the connection is convenient.
1.4 complete the experiment
(1) adjustable differential relay cognition experiment
