ABB Unveils PF900-NR (3BDH000357): Non-Redundant Power Supply for Uninterrupted Control System Operation
ABB has introduced the PF900-NR, cataloged under the part number 3BDH000357, a high-performance, single-module AC/DC power supply unit designed for reliable operation in industrial automation and control systems. This unit provides stable and conditioned 24V DC power essential for powering critical components such as PLCs, I/O modules, communication devices, and sensors in a wide range of industrial applications.
Engineered for robustness and efficiency, the PF900-NR power supply is built to deliver consistent, clean DC power from standard AC mains, even in electrically noisy and harsh industrial environments. Its compact, DIN-rail mountable design simplifies installation in control panels, while features like active power factor correction (PFC) and high immunity to voltage fluctuations ensure energy-efficient and stable operation. The «NR» designation indicates a non-redundant, single-module configuration suitable for applications where ultra-high availability via parallel redundancy is not required.
«A reliable power source is the silent backbone of any automation system. Even a momentary hiccup can disrupt production,» said a product manager from ABB’s Electrification division. «The PF900-NR is engineered for steadfast performance. It provides clean, regulated power to sensitive electronics, protecting them from line disturbances and ensuring the overall stability and uptime of the control system it serves.»
Key Features and Benefits of the PF900-NR (3BDH000357) include:
-
High Efficiency with Active PFC: Features active Power Factor Correction (PFC) to improve energy efficiency, reduce harmonic distortion, and comply with stringent international energy standards, thereby lowering operational costs and electrical stress.
-
Wide Input Voltage Range: Accepts a broad range of AC input voltages (e.g., 85-264V AC), making it suitable for global use and resilient against typical line voltage sags and surges without disruption.
-
Stable and Clean DC Output: Delivers a tightly regulated 24V DC output with low ripple and noise, critical for the reliable operation of sensitive digital and analog control electronics.
-
Compact and Easy to Install: Designed for simple DIN-rail mounting in standard control cabinets, with clear status indicators (LEDs) for power and fault conditions, facilitating quick installation and visual diagnostics.
-
Robust Industrial Design: Built with high-quality components and conformal coated PCBs where applicable, offering high immunity to electrical noise, vibration, and temperature variations common in industrial settings.
The PF900-NR power supply (3BDH000357) is available now for integration into new control panel designs or as a direct replacement for existing power units. It is an ideal choice for machine builders, panel integrators, and plant maintenance teams seeking a dependable, efficient, and compact power solution for a wide array of industrial automation applications.
