EEC4746

A kit of Power Electronics devices, mounted on small printed circuit carriers, which are housed in a convenient storage tray with identification information. The kit introduces the student to device characteristics and dc motor control methods, including PWM motor control. The hardware includes a dc motor module with optical incremental encoder and eddy current brake.

The circuits are constructed on the EEC470 construction deck. The deck's layout allows swift and simple circuit construction and the high quality beryllium copper spring contacts have a self-cleaning action to ensure a long life of good electrical contact.

The combination of EEC470 and EEC476 requires a 92-445 Power Supply.
