- Designed to mount alongside and power the PM 802F or PM 803F Central Processing Units (CPUs)
The SA811F 3BDH000013R1 is a high-performance system power module designed and manufactured by ABB, a giant in industrial automation. This module can be installed locally or in a rack. It is designed to convert highly volatile industrial AC mains power into the clean DC power required by the system's internal logic circuitry, providing uninterrupted and highly reliable power support for controller core processor modules (such as the PM 802F and PM 803F) and the underlying I/O expansion bus.
This module integrates a robust safety protection matrix, providing overload detection, output short-circuit protection, and a power-off momentary hold function of up to 20 milliseconds, effectively resisting high-frequency surges and voltage drops in industrial environments. Simultaneously, it integrates real-time input/output voltage monitoring circuitry, which can synchronously send power-off warnings and fault diagnosis signals to the CPU motherboard via the backplane, ensuring the data security of the entire control station.
The SA811F 3BDH000013R1 ABB Power Supply Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Logic Isolation: As the primary electrical filter in the AC 800F basic package, it protects precision-designed chips and communication cards from field power fluctuations, surges, or noise.
Industrial Applications: Widely used in automated batch processing, petrochemical process loops, and substation sensor monitoring arrays, where a stable power supply prevents data corruption.
The SA811F 3BDH000013R1 employs a high-frequency switching power supply (SMPS) topology and a high-isolation feedback control mechanism. When a 115V/230V AC high voltage is input, the voltage first passes through an onboard electromagnetic compatibility (EMC) filter and power factor correction (PFC) circuit to eliminate grid harmonics and limit inrush current.
Next, the rectified and filtered DC high voltage is modulated into a high-frequency pulse voltage of tens of kilohertz by a high-speed power electronic switch (e.g., MOSFET) and input to the primary side of a high-frequency isolation transformer. Utilizing the electromagnetic conversion principle of the transformer, a low-voltage high-frequency pulse is output from the secondary side. After rectification by fast recovery diodes and LC filtering, an extremely stable low-voltage DC power supply (e.g., a 24V DC power supply for the system bus) is finally output.
During operation, an internal micro-sampling network captures output voltage fluctuations in real time and provides reliable isolation feedback through an optocoupler, dynamically adjusting the duty cycle of the switching transistors (pulse width modulation, PWM). This ensures that even if there are drastic changes in the power grid or load, the output voltage can be precisely locked within the standard safe range.
