2 of the "Design Specification of Power Distribution Systems" GB50052-2009, it explicitly stipulates that primary loads should be powered by dual power sources. This means that in power supply, the highest level of load, namely the primary load . Referring to Article 3. These two circuits are considered to be mutually independent and unaffected in terms of power supply. The ATS Dual Power Distribution Box plays a pivotal role in providing efficient low-voltage power solutions, ensuring that power flows seamlessly, even in the event of an outage. Under normal operation, the PSUs are load sharing, drawing approximately equal current from the utility (electricity supply) and providing approximately equal current to the load. From factories and offices to sensitive areas, this device guarantees that everything is safe and working smoothly. But what are the behind mechanisms? Let's delve deeper!DC power supplies may be connected in series, parallel or redundant configuration depending on the application need. When higher current load or load sharing is needed then power. For many years, AC-DC power supplies for the medical market are not only safety certified to the IEC 60601-1 medical standard, but also to the industrial IEC 60950-1 / IEC 62368-1 standards.
