UPS power supply dual-bus system
A dual-bus system consists of two independent UPS systems. Of the two UPS systems, one is a master system, and the other is a slave system. The Internet Data Center (IDC) and Multimedia Data Center (MDC) are the control centers of the high-speed Internet. Users have extremely high requirements for the "timeliness" of the remote processing, storage and transfer of information resources (data, voice and image information) they undertake. This design makes the dual-bus system highly reliable and suitable for. In modern industrial automation and process control systems, ensuring uninterrupted power supply is critical, especially for sensitive instrumentation such as Distributed Control Systems (DCS), Safety Instrumented Systems (SIS), and Programmable Logic Controllers (PLC).
