Trash > Electronic Trainer

Electronics Trainer KL-200 Features Ideal for electronics circuit experiments and design exercises. Integrated training system, with complete curriculum. Built-in power supplies and test facilities for easy and efficient experimentation. Large breadboard for circuit design and prototyping. 17 experiment modules form basis for over 110 fully documented experiments. Main units and experiment modules also available separately for economical construction of class sets. The KL-200 Electronics Trainer is a comprehensive and self-contained system suitable for tuition and experimentation with a range of electronics circuits.   KL-200 Main Unit The main unit incorporates all necessary equipment for use with the eleven plug-on training modules. Power supply, function generator, and analogue and digital meters are all built-in. The DC power supply provides fixed ±5V and ±12V at 0.3A, a variable ±3V ~ ±18V at 1A, and a transformer provides a 9V~0V~9V AC output at up to 500mA. The function generator offers sine, square, and triangle waveforms at frequencies from 10Hz ~ 100kHz in 4 ranges. The main unit is also supplied with a removable 1680 tie point universal breadboard for general experimentation and prototyping.   KL-200 Experiment Modules Seventeen modules form the basis for over 110 experiments detailed in the comprehensive experiment manual. Each module contains the experiment circuit which is clearly illustrated by a cicuit diagram on its top panel. Switch faults are also incorporated into the modules for simulating fault situations.
