Abstract:
Every years students electronics engineering was increased. With implementations
increase students then instrumentation laboratory was terminate. For using instrumental in
the laboratory decreased quality because many instruments was malfunction. In this final
project litterateur was design a “Trainer Kit Emergency Lamp” for helping students in the
practice power electronic. This trainer kit emergency lamp have two system such as
charging system (baterry charger) and switching system (relay). For charging system
(battery charger) using voltage comparator IC CA3140 with histerisis, while switching
system in the trainer kit have function for automatic switch between trainer kit with
emergency lamp. Histerisis in the battery charger have function for voltage comparator
battery. Voltage comparator charger battery is a 12,09 volt DC. When condition battery
voltage under 12,09 volt DC then charger battery will be charging battery until battery
voltage was 12,09 volt DC. When voltage battery was 12,09 volt DC it will be no longer
charging for battery.
