DC Motor Control Trainer

Product Overview

The system consists of a series of modular plug-in panels modules housed in a compact epoxy coated casing. Each modules represents one or more electrical / electronics components or block diagram of a complex circuits. All functional parts of the components are mounted inside the modules with circuit symbols / mimic diagrams screen printed on the front PCB panel and terminated at 4mm safety sockets for student experimental practice.

All modular plug-in panels modules are interconnecting together by using 19mm Bridging Plug Set and 4mm stackable safety test leads sets to form the desired control circuits.
