AN AUTOMATIC TRANSFER SWITCH BASED ON ZELIO PROGRAMMABLE LOGIC CONTROLLER USING RENEWABLE ENERGY

Advances in technology and the use of automated control systems have made it easy togain the reliability of a system. Along with the development of technology, demanded thereliability of a system in use. For that in need of refinement of the control system, amongwhich the control system in use is Automatic Transfer Switch by using the ProgramableLogic Controller Zelio as a control unit. For energy saving method used solarcell thatcan move automatically follow the direction of the sun, as a replacement power supplyfrom PLN is in use to meet daily needs. This study uses PLC as a control system, wherePLC will control ATS that is by turning on solar cell automatically, when there is apower outage.
