Product Introduction
The ABB BSFC-02C Charging Control Board (part number 3AXD50000011461) is a critical component designed for use within ABB’s ACS880 drive systems. This board plays a vital role in managing the pre-charging process of the DC bus capacitors, effectively limiting the inrush current during startup. By doing so, it ensures the longevity and reliability of the drive system while preventing electrical damage to downstream components. The BSFC-02C is built to operate efficiently under various industrial conditions and integrates seamlessly with other ABB drive components.

Applications
The BSFC-02C is primarily used within ABB’s ACS880 inverter drives to manage the controlled pre-charging of DC bus capacitors. This function is essential for preventing large inrush currents which can damage both the power electronics and mechanical components of the drive system. It is commonly found in industrial applications such as:
-
Heavy machinery drive systems (conveyors, cranes, hoists)
-
Pumps and compressors in oil and gas or chemical plants
-
Steel and metal processing lines
-
Marine propulsion drives
-
Any high-power motor control systems requiring reliable and safe startup
Advantages
-
Robust Pre-Charging Control: By controlling the inrush current, the board extends the lifetime of the DC bus capacitors and other electrical components.
-
Dual Voltage Operation: Supports both 115 VAC and 230 VAC power supplies, making it flexible for multiple regional installations.
-
Integrated Safety Fuse: A 2 A slow-blow fuse protects the board from overload, reducing risk of failure.
-
Compact and Lightweight: Its small size and low weight allow for easier integration into control cabinets without adding significant bulk or weight.
-
Wide Operating Temperature Range: Designed to operate reliably in harsh industrial environments.
-
Seamless Integration: Perfectly designed to fit with ACS880 drive families, maintaining ABB’s high standards for system compatibility and performance.
