CL-1121A CIRCUIT BOARD FOR RLC WITH AC - Version A + Add to wishlist


The ConsuLab CL-1121A is a circuit board that permits students to learn how to use RLC circuits fed by alternating current. The components are mounted on the circuit board so as to view the circuits identified by section. The circuit board is attached on a plastic base that protects the solder side and stands on four non-slip rubber legs.



  • Allows students to test an electrical circuit.
  • Allows students to analyze circuit schematics.
  • Allows students to measure various circuit points and calculate electrical values.
  • Designed to be used in experiments dealing with electrical circuit testing applied to electromechanics of automated systems.



  • One (1) resistance of 820 Ω (2 W, 5 %) connected in series with one (1) resistance of 200 Ω (2 W, 5 %).
  • One (1) resistance of 1.2 kΩ (2 W, 5 %) connected in series with one (1) capacitor of 1 μF (160 VAC);
  • One (1) coil with 2H inductance.

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.
