The SB5G-ESS is a high-reliability power control and protection board designed for use in industrial energy systems such as Energy Storage Systems (ESS), power inverters, and power distribution modules. This board integrates fast-acting Littelfuse KLKD 4A fuses (600V AC/DC) along with solid-state relays, STMicroelectronics power transistors (MOSFET or IGBT), current shunt resistors, and heavy-duty terminal blocks.

Engineered to ensure protection against overloads and short circuits, the SB5G-ESS enables precise management of high-voltage circuits while maintaining compact design and efficient heat dissipation. Ideal for OEM energy applications requiring industrial-grade reliability.
