The BUF8600 4s module provides a high-density energy storage solution for SITOP PSU8600 power supplies, specifically targeting medium-duration power interruptions.

High Cycle Life Storage

By using double-layer capacitors, this module offers an almost unlimited number of charge/discharge cycles, far exceeding the lifespan of conventional battery-based backup systems.

Efficient System Protection

It provides sufficient time (4 seconds at full 40A load) to maintain control voltage during significant network fluctuations, ensuring sensor data integrity and PLC state retention.
