Features:

  • Amplifies low-level control pulses to accurately drive high-power semiconductor switching devices.
  • Converts 100-240 V AC input into stable DC power for the board and associated control circuits.
  • Separates control and power circuits to improve system protection during overload and short-circuit conditions.
ABB SAFT171PAC plays an important role in industrial drive control systems by providing the interface between the central controller and the power switching stage. Pulse signals generated by the controller are typically too weak to operate high-power semiconductor devices directly. The board strengthens these signals before they reach the output stage, allowing stable and accurate switching performance. This function supports dependable operation in demanding industrial automation applications.

Beyond signal amplification, ABB SAFT171PAC combines power supply functionality within the same board. A wide input voltage range of 100 V to 240 V AC at 50/60 Hz allows installation across different industrial power systems without requiring additional input voltage adaptation. The converted DC output supplies the board and nearby control circuits with reliable operating power, helping simplify the overall system architecture.

ABB SAFT171PAC is intended for use with ABB Stromberg drives and incorporates electrical isolation between high-power and low-power sections. This design helps reduce the possibility of damage to the central control unit if overload or short-circuit faults occur in the drive system. With an operating temperature range of -10°C to +55°C and an IP20 protection rating, the board is well suited for installation inside protected industrial control cabinets where long-term operational reliability is required.

The SAFT171PAC ABB Pulse Amplifier Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
ABB SAFT171PAC pulse amplifier board serves as a key interface between the central control unit and the power switching stage in ABB Stromberg drives. Weak pulse signals generated by the control system are amplified to a level capable of driving high-power semiconductor switching devices such as IGBT, GTO, or thyristor components with greater precision and stability.

In addition to pulse amplification, ABB SAFT171PAC functions as a power supply board. It accepts a wide AC input voltage range from 100 V to 240 V at 50/60 Hz and converts the incoming power into stable DC voltage required by the board and surrounding control circuits. This integrated design supports reliable operation under different industrial power conditions.

Electrical isolation is another important function of ABB SAFT171PAC. The board separates the high-voltage drive section from the low-voltage control system to improve operational safety. During overload or short-circuit conditions, the isolation function helps protect the central controller from damage. With an operating temperature range of -10°C to +55°C and an IP20 protection rating, the board is suitable for installation inside industrial control cabinets used with ABB Stromberg drives.
