The power circuit is protected by a thermal magnetic breaker and the control circuit is protected by diodes. Connections can be made between the three-phase power supply and other components in the circuit through 4mm standard color-coded safety sockets using banana plug jumper leads. The SCR Direct Current Motor Speed Controller allows students to study the operation of a silicon-controlled rectifier used in motor speed control experiments. Specifications and/or diagrams are silk-screened on the back of a clear-plastic front panel for ease of identification. Included in the Rotating Machines Trainer (50016) for 1/3 hp - 250 W. Requires a 120V 60Hz circuit. The trainer is protected by a either a diode or thermal-magnetic circuit breaker.

The Cutaway Scroll Type design is equipped with an operational OEM 12VDC electromagnetic clutch that can be applied or disengaged with a switch. Amount of slippage is adjustable by a control knob. Also includes a feature that allows the demonstration of improper performance caused from a slipping compressor clutch.
Main Features:
Features a control that allows engagement or disengagement of the compressor clutch circuit.
Allows visualization of internal operation of a scroll-type AC compressor.
Can demonstrate the improper performance caused from a slipping clutch.
Driven by hand crank.
Requires a separate power supply or 12VDC battery to operate.
Clutch control is protected with a 5A replaceable fuse.
The Alternator Trainer PCM Controlled alternator trainer with a PCM controlled voltage regulator contains a variable speed drive that modulates alternator input (engine speed) as in an actual vehicle. The alternator has been modified to accommodate a load current of 25A in order to demonstrate the full load charging characteristic and allow the regulator to run at 100% capacity. The Alternator Trainer PCM Controlled is a simulator that allows instructors to demonstrate the operation of automotive charging systems controlled by a PCM. The synoptic diagram and the layout of all the control and instrumentation units provide clear and simple operation to the user. The trainer is very reliable and equipped with all safety equipment required for demonstration. After the engine is started and running, the alternator takes over as the source of power and the battery then becomes part of the load on the charging system. The student can see how the regulator controls the alternator output as the speed and load vary.
Educational Advantages:
Drive belt enclosed in safety shield
Test points for diagnosis
Driven by 120VAC electric motor
Built-in voltmeter and ammeter
PCM-controlled regulation
Optional built-in diagnostic fault box with 4 faults.
