Date:July 2-4,2025 Location:Bangkok International Trade & Exhibition Centre, Thailand Booth No.: Hall 2, J46 Thailand's energy landscape is undergoing a significant transformation. With the implementation of its 2018-2037 Power Development Plan, the country is accelerating its move towards a future of low-carbon, high-efficiency, and smart grid future. Regarding energy structure, Thailand aims to substantially increase renewable energy's share of total power generation from 20% in 2023 to 51% by the end of 2037, presenting substantial opportunities for power protection technologies that ensure grid stability and equipment safety.

Fast Shutdown refers to a safety feature implemented in solar power systems that allows for the rapid deactivation of the system in the event of an emergency or when maintenance is required. This feature is especially important for photovoltaic (PV) systems, where solar panels generate electricity even when disconnected from the grid. Fast Shutdown ensures that all high-voltage components are quickly de-energized to protect both first responders and maintenance personnel from electrical hazards.
