Case Study of Power Supply Adoption at High Temperatures: Fiber Optic Base Station Power Supply in Singapore
This is a case of a switching power supply adopted for fiber optic base stations (AG BOX) in Singapore, a world-class advanced IT country!
**Background** In the 2016 World Economic Forum, Singapore was recognized as "the most digitally advanced country in the world" with a score of 6.04 out of 7 on the NRI index. As part of its national strategy, Singapore is promoting a cutting-edge digital smart city project utilizing digital technologies. **Challenges** The fiber optic base stations (AG BOX) spread throughout the city are key to the project's success. However, the temperature inside the devices reached 65°C, which posed challenges for operational reliability with conventional power supplies from other companies. PULS's DIN rail switching power supply minimizes thermal loss and achieves high efficiency of 95%. It generates less heat, is compact, and has a fanless structure, making it maintenance-free, which led to its adoption for this project. For more details, please check the case study. **Contents** - Background of Singapore's smart city national plan - Explanation of AG Box - Aggregation Gateway Box - Power supply requirements under extreme high temperatures - Explanation of the DIMENSION Q series
