RUIJIE RG-NIS-PA240-54 - POWER SUPPLY

The Ruijie Reyee RG‑NIS‑PA240‑54 is a high‑capacity 240 W industrial DIN‑rail power supply engineered to deliver stable, reliable 54‑volt DC output for mission‑critical networking, PoE systems and industrial automation equipment. Designed for harsh environments and continuous operation, it provides exceptional electrical performance, wide input compatibility and comprehensive protection features — making it ideal for powering Ruijie industrial switches, dense PoE deployments, CCTV networks and field‑installed control systems.

Built with a universal AC input range of 90–264 V AC, the RG‑NIS‑PA240‑54 ensures dependable operation across global power standards and unstable grid conditions. It delivers a regulated 52.38–55.62 V DC output at 4.4 A, providing a full 240 W of clean, stable power for high‑demand devices. This output specification is consistently confirmed across multiple datasheet sources.

Engineered for industrial reliability, the RG‑NIS‑PA240‑54 features a fanless passive‑cooling design, eliminating moving parts and ensuring silent operation while reducing dust accumulation and mechanical wear. Its MTBF exceeds 150,000 hours, supporting long‑term 24/7 operation in demanding environments.

The power supply includes comprehensive protection mechanisms such as short‑circuit, over‑current, over‑voltage, over‑temperature, surge protection (4 kV common‑mode / 2 kV differential‑mode), and ESD protection (8 kV air / 6 kV contact). These safeguards ensure stable operation and protect connected equipment from electrical anomalies, making it suitable for electrically noisy industrial sites.

Designed for harsh environmental conditions, the RG‑NIS‑PA240‑54 operates reliably from –40°C to +70°C, with thermal derating curves for extreme temperatures. It supports 5%–95% non‑condensing humidity and installation altitudes from –500 m to 5000 m, making it suitable for factories, warehouses, transport hubs and outdoor control cabinets.

The unit features a rugged metal DIN‑rail chassis measuring 52 × 110 × 125 mm and weighing 0.75 kg, allowing easy integration into industrial control panels and network enclosures. A front‑panel DC OK LED indicator provides real‑time status monitoring for quick diagnostics.

Certified to CE, EN 62638‑1, EN 55032, IEC 61000‑4‑2/4/4/5/6, and related EMC standards, the RG‑NIS‑PA240‑54 meets stringent safety and electromagnetic compliance requirements for industrial deployments. Its fanless, noiseless design and robust metal housing make it ideal for continuous operation in environments where reliability is paramount.

Perfect for powering Ruijie Reyee industrial switches such as the RG‑NIS2100, RG‑NIS31‑4G2S‑HP, and RG‑NIS31‑8G2S‑HP, the RG‑NIS‑PA240‑54 delivers dependable 54 V DC power for PoE systems, CCTV networks, automation controllers and field networking equipment. It stands as one of the most reliable and efficient DIN‑rail power supplies in the Reyee industrial lineup, offering stable performance, wide environmental tolerance and long‑term durability.
