ELECTRONIC CONTROL TRAINER Description and Specifications for Lab Tenders
ELECTRONIC CONTROL trainer
This trainer should provide
a comprehensive course on Solid State Relays (SSR) and their applications
ELECTRONIC CONTROL TRAINER, ELECTRIC ELECTONICS LAB.
SSR’s are typically used as the modern replacement to conventional electromagnetic relays. SSR’s generally provide more flexibility in their control applications and easily combine low voltage and high voltage circuits working in conjunction with each other. This trainer also provides a good introduction to semiconductor applications and theory.
· The trainer features three low voltage circuits which controls the solid State Relay that in turn controls a higher voltage circuit.
· The low voltage circuits include a touch operated switch circuit, a sound operated switch circuit and an optical photo relay switch.
· A mode selection switch is used to determine which low voltage circuit will control the SSR. The SSR will then be turned off or on by this circuit.
· The SSR has an output of 220-240 VAC, single phase, 50 Hz, 16 amp and can control electric motors, lights or any other electrical device.
· Experiments covers the basic types of semiconductors, details on the touch control switch, details on the construction of the sound control switch, details on the Photo-Optical switch, comparison of electromechanical relay to SSR’s, characteristics of SSR and basic SSR design applications. SCR and TRIAC basics are also covered.The Student Job Sheet sectioned is asked to includes detailed experiments for the student to follow.
