Acrel Cloud-3100 Prepaid System for Thailand Shinawatra University

During their time at university, students primarily spend their activities within the campus dormitories. Effective management of electricity in dormitories is fundamental to ensuring orderly administration. There are three crucial aspects involved in managing dormitory electricity: safety management, electricity metering and billing, and energy conservation. Exploring the current state of electricity management in university dormitories and addressing the issues in these three areas is of significant importance. Developing effective strategies for these aspects is essential for improving the management of electricity in university dormitories.
