- Surge rating:Up to 4 kV (reseller listing) — improves resilience to transient disturbances in industrial environments.
- Standards:Designed to meet common industrial safety standards (e.g. IEC/EN/UL 62368 referenced); consult the official datasheet for exact approvals and certification marks.
- Form factor & mounting:TS35 DIN-rail mount; compact footprint (approx. 125 × 52 × 110 mm) for efficient cabinet use.
- Weight:Approximately 0.75–0.87 kg — light enough for ease of handling in tight enclosures.
- Operating environment:−40 °C to +70 °C operating temperature, storage −40 °C to +85 °C, humidity 5–95% RH non-condensing — suitable for a wide range of industrial and outdoor-adjacent installations.
- Connectors:3-pin AC input and dual DC output terminals for secure wiring.
Warranty & support:3 years manufacturer warranty (service summary). As with any industrial power product, installation and servicing should be performed by qualified personnel and wiring must follow local regulations and the supplied installation guide.
Use cases and scenarios where the RG-NIS-PA240-54 excels
This power module is purposeful in any setting that needs a robust and compact 54 V DC supply. Typical applications include:
- Industrial networking cabinets:Centralized power for industrial Ethernet switches and media converters inside control cabinets or telecom enclosures.
- Railway and transportation systems:Powering network nodes and communication modules where wide temperature range and surge protection are essential.
- Factory automation:Feeding controllers, networked sensors and edge switches in manufacturing lines with strong resistance to electrical noise and temperature stress.
- Security and surveillance:Supplying network video recorders (NVRs), PoE switches or remote surveillance nodes that require stable 54 V inputs.
- Small-scale telecom/utility sites:Backup or primary supply for remote network equipment in substations and utility cabinets.
- Field or contractor deployments:The DIN-rail form factor and built-in protections simplify installation for integrators installing Ruijie/Reyee network kits.
Why it excels: the combination of dual outputs, a visual DC-OK indicator and broad environmental ratings mean the RG-NIS-PA240-54 minimizes downtime, simplifies diagnostics and reduces the number of separate components required in many small to mid-sized systems.
Comparisons with similar products on the market
When comparing industrial DIN-rail power supplies, buyers typically evaluate output voltage, wattage, protections, certifications and footprint. Here’s how the RG-NIS-PA240-54 stacks up against common alternatives:
- Many general DIN-rail models offer similar wattage but at standard 12 V or 24 V outputs. The RG-NIS-PA240-54’s 54 V nominal output is purpose-built for 54 V network equipment, avoiding the need for additional step-up converters.
- Some competitors provide higher wattage options, but at the cost of larger size and higher heat output. The Ruijie module finds a balance between power density and compact mounting footprint.
- Other network vendors may supply matched power supplies for their switches; the RG-NIS-PA240-54 is designed to pair directly with Ruijie/Reyee industrial devices, ensuring voltage compatibility and physical fit for many Ruijie installations.
- Compared to premium industrial brands (e.g., well-known DIN-rail power specialists), Ruijie’s unit is competitive on features such as wide input range and protections while often delivering attractive pricing for network-focused deployments.
Selection tips: choose a power module that matches the required DC voltage, provides adequate headroom for peak loads, includes necessary protections and meets the installation environment’s temperature and certification needs. If powering PoE devices or multiple modules, calculate total current draw and consider redundancy or higher-wattage alternatives if you anticipate future expansion.
Customer feedback and practical observations
While specific user reviews vary by deployment, common themes emerge from field feedback on similar Ruijie industrial power modules:
- Installer perspective:"Compact and easy to mount on the DIN-rail; having dual DC outputs saved us from adding a separate distribution block." — typical feedback from integrators appreciating the space savings.
- Operations team:"The DC-OK indicator makes routine health checks fast; we can spot a failed power module without opening the cabinet." — a frequent comment highlighting reduced troubleshooting time.
- Reliability notes:Users deploying in outdoor-adjacent cabinets have noted the robust operating temperature range and surge protection helped maintain service through harsh weather and electrical disturbances.
Note: These illustrative statements reflect common customer sentiments for products of this class; consult seller reviews or case studies for direct user testimonials pertaining to the exact RG-NIS-PA240-54 unit.
