Load switch

Load switch .
This module must be developed in order to apply  a load to the two pole output electric machines and it shall be controlled both manually and automatically.
Technical features:
•Power supply: +15 V ; 0 V ; -15 V
•Input voltage: max. 220 Vac
•Load: 3 incandescent lamps
It must be mounted on an insulated didactic module, it must  show a schematic diagram and 4 mm safety terminals for the electrical connection;  three switches for the manual control of the load, electronic control relay for the automatic control of the load, safety junctions both for the connection of the input voltage and for the connection of the rectified output voltage and three real incandescent lamps. It must include also a bus for the supply that allows the connection between the panels.
Matching amplifier
This module must operate as matching element between signal voltage levels and standard voltages used in automatic control systems.
Technical features:
•Power supply: -15 V/0 V/+15 V
•Input signal range Ui: -50 V . . . + 50 V
•Coarse and fine gain setting: 0÷1/0÷10/0÷100
•Connectable low pass filter with coarse and fine time constant setting: 0/ 1÷10 ms / 10÷100 ms
•Connectable output offset voltage: -10 V . . . +10 V
It must be mounted on an insulated didactic module, it must show a schematic diagram and 2 mm terminals for the electrical connection;  three potentiometers, two selectors plus one switch. It must include also a bus for the supply that allows the connection between the panels.
