Key features at a glance
- 150 W maximum output— 12 V DC, up to 12.5 A.
- Redundant / parallel operation— supports current sharing between two installed modules for higher reliability.
- Hot‑swappable— modules can be inserted or removed while the host switch remains powered, supporting live maintenance.
- I2C monitoring interface— real-time status and management reporting to the host chassis.
- Protections— undervoltage, overcurrent, overvoltage and short‑circuit protections are built in.
- Environmental resilience— conformal coating for moisture and contaminant protection plus wide operating temperature and humidity ranges.
Detailed specifications and benefits
The RG-PA150IB-F is engineered for modern modular switches where uptime, maintainability and predictable power delivery are priorities. Below are the important technical details and how they translate into real operational benefits.
- Input voltage:100–240 V AC (operating range 90–290 V AC). This wide AC range simplifies global deployments and tolerates line fluctuations common in enterprise and edge environments.
- Input frequency:50/60 Hz (47–63 Hz), and HVDC input support (192–288 V DC). These options give flexibility for sites with DC power distribution or mixed grid conditions.
- Max input current:3 A and low input leakage (≤ 3.5 mA), keeping upstream electrical loads predictable.
- Output voltage and power:12 V DC up to 12.5 A for a maximum of 150 W. This is suitable for many switch line cards, integrated fans and management subsystems.
- Redundant operation:Designed for parallel operation — two modules can share current and provide graceful redundancy if one unit fails. That enables maintenance without downtime when configured correctly.
- Monitoring:I2C status reporting gives the host chassis visibility into power health, alarms and fault conditions, enabling proactive maintenance and integration with network management systems.
- Protections:Built‑in undervoltage, overcurrent, overvoltage and short‑circuit protections protect both the module and the host switch from electrical faults.
- Conformal coating:Coating on critical circuitry improves resistance to moisture and airborne contaminants, making the module more robust in less-than-ideal environmental conditions.
- Operating range:Temperature −10 °C to +55 °C, storage −40 °C to +70 °C, and 5% to 95% non‑condensing humidity accommodate most data center and campus deployments.
- Physical:Compact form factor (196 mm × 50.5 mm × 40 mm) and modest weight (0.55 kg) makes it easy to handle during hot‑swap operations; airflow is rear‑to‑front (primary), so chassis cooling design should match.
Benefits summarized
- High availability:Redundant, hot‑swappable modules reduce planned and unplanned downtime, supporting continuous service.
- Operational visibility:I2C reporting enables alerts and monitoring to be integrated into switch management for faster fault diagnosis.
- Global compatibility:Wide AC and DC input ranges ease international deployment and tolerance to power variability.
- Durability:Conformal coating and multiple protections extend service life in challenging environments.
Use cases and scenarios where the RG-PA150IB-F excels
This power module is tailored to scenarios where modular switches are used and uptime is critical. Typical deployments include:
In campus networks and enterprise cores, the ability to maintain and swap power modules without disrupting traffic is crucial. The RG-PA150IB-F’s hot‑swap capability and redundancy support mean maintenance can be performed during business hours with minimal impact.
For leaf and top-of-rack switches servicing high-density server racks, reliable power and monitoring are essential. Dual-module redundancy with current sharing provides headroom and rapid failover in case one module degrades or is removed.
Remote branch offices or edge sites that have less controlled environments benefit from the module’s conformal coating and wide operating ranges. The unit’s compact size and straightforward hot‑swap process make field service simpler.
Where service continuity is a contractual requirement, redundant power modules help meet SLAs. I2C-based alarms can feed into NOC dashboards for faster incident response.
How the RG-PA150IB-F compares with similar market offerings
Power modules for modular switches are offered by many vendors. When comparing the RG-PA150IB-F to comparable products, consider three main axes: power capacity and efficiency, management and monitoring capability, and environmental/robustness features.
- Power capacity:At 150 W (12 V / 12.5 A), it sits in the mid-range for switch power modules. Higher-capacity modules exist for larger chassis, while lower-capacity units target smaller devices. Choose based on aggregated load and headroom requirements.
- Management interface:The I2C status interface is a common and effective method for module-host communication; competitors may use similar protocols or proprietary interfaces. The presence of I2C simplifies integration with chassis firmware and NMS platforms.
- Resilience and protections:Not all modules include conformal coating or the same breadth of protection features. The RG-PA150IB-F’s conformal coating gives it an edge in harsher environments versus bare PCBA designs.
- Hot‑swap and redundancy:These are standard expectations for modern modular power modules. The RG-PA150IB-F’s explicit support for parallel current sharing and hot‑swap ensures it meets enterprise-class maintainability expectations.
When evaluating alternatives, verify form factor compatibility with your chassis, confirm monitoring protocol support, and compare thermal and acoustic impacts as well as vendor support and warranty terms.
Customer testimonials and feedback (typical impressions)
Specific customer testimonials for this exact module are not supplied here. However, feedback typical of enterprise-grade redundant hot‑swap power modules—and what you can reasonably expect from a well-designed unit like the RG-PA150IB-F—includes:
- "Hot‑swap works as advertised — we can replace a module during maintenance windows without traffic impact when redundancy is configured properly."
