ST1112 training bench of a chopper with load education laboratory equipment
1 product overview
1.1 overview
By chopper of relevant experiments, can be familiar with the characteristics of the chopper, grasp its control principle and control mode, the corresponding knowledge and skills, suits, higher vocational colleges, secondary vocational schools and vocational school related professional teaching and skills training examination.
1.2 features
(1) the training platform adopts the frame structure of aluminum profile, which can be moved flexibly. The measuring instrument and the actual training power supply built-in integration installation, easy to use, not easy to damage.
(2) the actual training platform is fully configured, and the modules can be used in combination to complete a variety of training contents.
(3) the training platform has a good security system.
2 performance parameters
(1) input power: two-phase three-wire system 220V plus or minus 10% 50Hz
(2) external dimension: 600mm x 400mm x 1300mm
(3) unit capacity: < 0.5kva
