Product Specification
The SCR, TRIAC and UJT Characteristics Trainer is specially developed to provide students with practical knowledge of power semiconductor devices through hands-on laboratory experimentation. Manufactured by Micro Technologies, this trainer enables learners to understand the operating principles, triggering mechanisms, and switching characteristics of SCR, TRIAC, and Unijunction Transistor (UJT) devices used in modern electronic and industrial control applications.
The trainer supports detailed experiments on the V-I Characteristics of Silicon Controlled Rectifier (SCR), TRIAC Characteristics, and UJT Characteristics. Students can study forward blocking characteristics, gate triggering, breakover voltage, latching current, holding current, peak-point voltage, valley-point voltage, negative resistance region, and bidirectional switching behavior. These experiments provide a clear understanding of semiconductor switching devices used in controlled rectifiers, AC power controllers, oscillators, triggering circuits, motor speed controllers, dimmers, and industrial automation systems.
The trainer incorporates onboard SCR TYN604, TRIAC BT136, and UJT 2N2646, allowing students to perform multiple semiconductor experiments using a single compact laboratory trainer. Each device is permanently mounted on the front panel, eliminating external component installation while improving experiment reliability.
Integrated digital panel meters provide highly accurate voltage and current measurements, enabling students to plot characteristic curves and analyze semiconductor performance with precision. Two independently regulated DC power supplies allow separate control of gate and device voltages through front-panel potentiometers, ensuring smooth voltage adjustment and repeatable experimental observations.
The front panel is manufactured using a premium insulated printed circuit board with permanently printed circuit diagrams and symbols for easy identification of components and test points. Color-coded 4 mm safety sockets provide secure laboratory connections and simplify wiring during practical sessions.
To ensure safe laboratory operation, the trainer incorporates fuse-based short-circuit protection, protecting both the equipment and users against accidental overloads. The complete system is enclosed inside a rugged ABS plastic cabinet designed for continuous educational use while maintaining a compact tabletop configuration.
The SCR, TRIAC and UJT Characteristics Trainer is extensively used in engineering colleges, universities, diploma institutes, polytechnic colleges, industrial training institutes (ITI), vocational education centers, semiconductor laboratories, power electronics laboratories, electronics laboratories, and research institutions for practical semiconductor education.
Every SCR, TRIAC and UJT Characteristics Trainer manufactured by Micro Technologies undergoes comprehensive quality testing to ensure operational reliability, measurement accuracy, safety, and long service life.
