Has two h/w versions: full size bench top version and table version.
There is an opportunity to investigate the systems of automatic regulation, subordinative and monitoring systems, based on the self-synchronous device and potentiometers, on the training system.
The training system allows to study programmable logical control devices, based on the programmable logical controller (PLC) «Mitsubishi Electric ALPHA-2», the system of automatic regulation of technical parameters and electric drives.
Structurally the unit consists of the body where the part of electric equipment, electronic boards, front panel and the tabletop of an integrated desktop are installed.
The following equipment is placed inside of the unit body:
- feed system;
- operational amplifiers;
- generator of rectangular-shaped signals;
- unit of load resistors;
- relay unit;
- pulse-width converter (PWC);
- measuring unit (digital devices at the panel);
- relay-contactor control unit (three-staged rheostat start of direct current motor (DCM) in the function of: current, EMF (electromagnetic force), speed or time, dynamic braking, reverse-current braking);
- analogue controllers are designed to study closed-loop systems (single-loop stabilization of current, speed or position and sub-regulation system);
- armature circuit resistors;
- dynamic braking resistor;
- power actuators.
Studied objects are located at the front panel:
- programmable logic controller (PLC);
- self-synchronous motors (2 pcs.);
- potentiometric sensors;
