Simple Automatic Transfer Switch System Using Timer Delay Relay

A control system in the form of an Automatic Transfer Switch (ATS) is needed when a blackout occurs from PLN that will be transferred to generator. The research problem was how save costs for making ATS can run efficiently. purpose this study find out well and efficient. method used Research Development. Development stages included: collecting data, designing, testing. To ATS, researchers Timer Delay Relay (TDR), as using TDR reduces cost tools because component prices are relatively affordable. way works electricity on, battery charged by charger, goes out, inverter get voltage supply battery, originally 12V changed 220V. makes it easier determine appropriate time stable. Based on experiment, stable 6 seconds.
