Redundant Power Supply for Network Protocol Analyzer

Product Specifications

Technical details and manufacturing context for Redundant Power Supply

Definition

The Redundant Power Supply is a critical component within the Multi-Protocol Network Protocol Analyzer that maintains uninterrupted device functionality during power disruptions. It consists of multiple independent power modules that automatically switch to backup units when primary power fails, preventing data loss, network downtime, and equipment damage during protocol analysis operations. The system is designed for high reliability, with an N+1 redundancy configuration where multiple power modules work in parallel. When the primary power supply fails or experiences voltage fluctuations, monitoring circuits detect the anomaly and seamlessly transfer the load to a standby power module within milliseconds, ensuring continuous power delivery to the protocol analyzer's processing units and network interfaces. The unit supports a wide input voltage range of 90–264 V AC and frequency range of 47–63 Hz, making it compatible with mains supplies worldwide. It provides a stable 12 V DC output with ±5% tolerance, and an output power range of 300–600 W to support the analyzer and peripherals. Efficiency is rated at ≥85%, meeting 80 PLUS Bronze standards, which reduces heat and energy costs. The switching time is ≤10 ms for seamless transfer to backup supply. The operating temperature range is -20 to 70 °C, and storage temperature is -40 to 85 °C, with relative humidity of 5–95% non-condensing. Ingress protection is rated IP20–IP54, suitable for dusty or wet areas. The mean time between failures (MTBF) is ≥100,000 hours, indicating high reliability for continuous operation. The unit has a compact 1U form factor with dimensions of 200 x 80 x 250 mm and weighs 2.5–3.5 kg. Materials include a printed circuit board, electronic components such as capacitors, resistors, and transistors, an aluminum alloy heat sink, and copper alloy power connectors. This product is a component intended for integration into the analyzer; verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The system operates on an N+1 redundancy configuration where multiple power modules work in parallel. When the primary power supply fails or experiences voltage fluctuations, monitoring circuits detect the anomaly and seamlessly transfer the load to a standby power module within milliseconds, ensuring continuous power delivery to the protocol analyzer's processing units and network interfaces.
