CL-151-1-50 SCR Speed Controller - 50 Hz + Add to wishlist


The SCR Direct Current Motor Speed Controller allows students to study the operation of a silicon-controlled rectifier used in motor speed control experiments. 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 φ standard color-coded safety sockets using banana plug jumper leads. Specifications and/or diagrams are silk-screened on the back of a clear-plastic front panel for ease of identification. The trainer is protected by a either a diode or thermal-magnetic circuit breaker. Included in the Rotating Machines Trainer (50340) for 1/3 hp - 250 W. Requires a 220V 50Hz circuit.

I got the half car out of the crate and working yesterday and today I had my Level 3 Electronic Climate Control diagnostics lab using it. This teaching aid is great! The workmanship and design is excellent and it is just perfect for the Level 3 curriculum, including the upcoming changes. We were fortunate that the IPro scan tool we received from the Uniselect donation communicates quite well with the Audi CAN bus system. The Audi also has the electronically controlled, clutchless compressor which is covered in our theory classes so it's a good reinforcement to be able to see it in action, manipulate it and communicate with it. I am very pleased with the quality and applicability of our ConsuLab products (including the engine/AC bench we got recently). They allow me to teach up to 8 students in great detail, whereas only one or two at a time can be involved in a full car. I am looking forward to the imminent arrival of our AC board. Thanks for your excellent insight of design and quality of manufacturing.
