ABB SS822

Details

1. Usage parameters

Working voltage: usually AC220V, adaptable within a certain voltage variation range, ensuring a good working foundation under normal power supply conditions, and providing reliable power supply for the system.

Output frequency: 50Hz, compatible with ABSS 822 public power supply, ensuring that the electrical load works normally under normal working frequency and meets the power supply frequency specifications of other electrical loads.

2. Product function

Power switching: ABB SS822 can be used as a power switching device, automatically switching the load to the backup power supply, and switching back to the main power supply after the power supply is restored, achieving seamless power transmission to the load, while preventing any equipment from shutting down, otherwise it will lead to uneconomical performance.

High reliability and fault-tolerant design: ABB 822 marks a major step forward in fault-tolerant architecture, avoiding single point failures by design, and significantly improving the robustness of the entire system. The robustness of the system is ensured in the past by selecting special high-reliability electronic devices, and the expected mean time between failures is more than 1.5 million hours, supporting long-term stable product use while minimizing maintenance and replacement costs.

Short switching time: Extremely fast power switching minimizes the interruption of the load and ensures that voltage-sensitive devices can work normally even during the switching process, effectively protecting the equipment from the impact of momentary power outages.

Intelligent control and monitoring: With the help of digital signal processing technology and patented conversion algorithms, it can accurately control and monitor the power supply status and provide detailed information through the CPU's LCD screen. In addition, a four-color LED display is installed in the communication module, which can feedback the operating status of the device itself, and understand its operating status and fault conditions at a glance, so that users have time to perfect repairs and maintenance.

Communication function: ABB SS822 supports PROFIBUS-DP communication protocol, with data transmission rates from 9.6k to 12M, and supports up to 126 bus devices. The master and slave stations basically exchange data periodically according to the rules defined by the EN50170 standard. Most non-periodic services (such as parameter setting, diagnostics) can also be performed by signal transmission between the master and its intelligent slave balance. In addition, the COM1 and COM2 ports (serial, RS232 or RS485) integrated in the AC500 can be used to communicate between other devices in a reasonable way. Among them, RS232 is a point-to-point communication standard with a maximum cable length of 15 meters, while RS485 allows multi-point communication with a maximum distance of up to 1.2 kilometers. Supports a variety of transmission media, the most commonly used is shielded twisted pair, using terminal resistors that comply with the RS485 bus specification.
