SD 802F | ABB SD802F Power Supply

Description

The SD802F Power Supply is a redundant power module designed for Modicon M2000 series PLC systems, as well as AC800F controllers, where it supplies power to CPU motherboards and modules in E1, E2, F1 to F4 slots. It features 1:1 redundancy, providing dual 24V DC backup power; when the main power fails, it switches to the backup power source in less than 20ms to ensure uninterrupted system operation, boosting overall system reliability. Key technical specifications include a 24V DC input (with ±25% tolerance and EMC filtering), 24V DC output, 5A output current, 26.5W total output power, and additional regulated outputs of 3.3V DC ±3% 5A and 5.0V DC ±3% 5A. Built with high-quality components, it delivers over 90% conversion efficiency for energy savings, and includes short-circuit and overload protection, plus input and output voltage monitoring with status signals to indicate operational and fault conditions. Its compact design (35mm x 30mm x 23mm, 20g) uses PC and ABS materials for easy installation, making it suitable for critical industrial control applications requiring continuous, stable power.
