3PS477.9
The B & R Automation 3PS477.9 power supply module is a core component of the System 2005 Controllers series, engineered for robust industrial automation. Designed for 24 VDC applications, it operates across a flexible input voltage range of 18–30 VDC (nominal 24 VDC) to accommodate diverse power sources. With a total maximum output power of 58.5 W, divided into 5 V: 40 W and 24 V: 50 W outputs, the module ensures reliable energy delivery to critical control and I/O segments. Its integrated expansion slave interface supports seamless system growth, positioning the 3PS477.9 as a versatile solution for continuous, high-performance power management.
Building on core performance, the 3PS477.9 delivers a maximum current draw of 3.5 A, while its input capacitance of 500 μF maintains voltage regulation under fluctuating loads. For protection against overloads and short circuits, it incorporates a 6.3 A time-lag fuse (250 V), ensuring system longevity and safety. The module’s architecture occupies two slots in the far-left backplane position, leveraging a double-width B&R 2005 module form factor that balances space efficiency with ease of installation. This design enables rapid deployment and straightforward integration within existing automation racks.
Additional resilience is provided by dedicated backup capacitors: 10,000 μF for single-phase systems and 6,000 μF for three-phase systems, safeguarding operation during momentary power interruptions. The far-left slot installation and secure backplane interface facilitate modular expansion, allowing multiple I/O segments to be added without system downtime. Manufactured by B & R Automation, the 3PS477.9 offers exceptional durability, scalability, and efficiency, making it an ideal choice for demanding industrial environments that require uninterrupted 24 VDC power delivery.
