    Application of DJSF1352 DC energy meter in PV energy storage system in Singapore

    Summary        Alternating current is more convenient and economical than direct current in high voltage transmission. However, in some application scenarios, the application of direct current to directly supply power to the DC load can make the circuit design simpler and more efficient. At present, DC power distribution in photovoltaic & energy storage systems can directly supply DC power through photovoltaic or batteries. It is also widely used in new energy power systems, such as solar street lights, DC air conditioners, and 5G communication base stations.   1. Project Overview       Singapore relies heavily on natural gas for power generation, but its own natural gas energy is not enough to support this huge natural gas consumption. 95% of the natural gas energy needs to be obta...

  • Acrel’s Hospital Isolated Power Supply Application in Pitsanulok hospital Project

    Abstract:With the widespread application of electronic medical equipment in hospitals, the threat of leakage current to patients is becoming greater and greater, especially in places where life is critical. The patients are directly exposed to various electrodes and sensors during surgery or anesthesia. Inserted into the human body, even the slight leakage current may cause the patient to be electrocuted. In addition, some medical equipment is used to maintain the lives of critically ill patients. Once the equipment is powered off, it will also threaten the lives of patients. Therefore, for the electrical design of the special place of the hospital, the IT system should be used for power supply in strict accordance with national standards and regulations.This article introduces the app...
