SID‑8BT‑A is a high-performance high-speed transfer controller designed for critical power systems. It supports millisecond-level transfer response and high-precision multi-channel A/D synchronous sampling (64 points per cycle), ensuring seamless switching to the backup source during power supply faults in auxiliary power systems.
The device integrates three switching modes—abnormal condition transfer, emergency transfer, and manual transfer—covering six switching logics including series, simultaneous, and parallel transfer. It also features intelligent protections such as bus voltage unbalance blocking, abnormal switch state detection, and fault locking, effectively preventing maloperations.
SID‑8BT‑A supports up to 3 seconds of waveform recording and event logging, and is equipped with dual Ethernet ports and multiple RS485 interfaces. It is compatible with standard communication protocols including IEC 61850, IEC 60870‑5‑103, and Modbus, making it ideal for high-reliability power supply applications in power plants, chemical industry, metallurgy, and other industrial sectors.
