Network Communication & Telecom Infrastructure 

1. Devices

Rack-mounted switches, routers, DSL/fiber termination gear, telecom base station ancillaries, and network edge nodes.

2. Key Requirements

• Fixed, Stable Output Voltage:Telecom platforms are built around tightly defined voltages, with 24V as a widely adopted standard. Fixed-rail supplies eliminate the risk of field misconfiguration.
• IEC 62368-1 Compliance:This standard has replaced IEC 60950-1 for IT and communication equipment in the EU, North America, and Asia-Pacific. Compliance is a market access requirement.
• Wide Operating Temperature Range:Outdoor cabinets face significant thermal variation. Office-temperature ratings become a reliability liability in these deployments.
• EMI Containment:Dense rack environments require power supplies to meet EMC limits, preventing cross-interference.

3. Recommended Solution: UES155-SPA-OP

• UES155-SPA-OPdelivers a fixed 24V output for network and telecom equipment. Its open-frame architecture integrates directly into host enclosures, saving cost and space in rack deployments.
• Certified to IEC 62368-1, the unit operates reliably from 10°C to 60°C, providing a compliant, field-proven power foundation for telecom OEMs.

5G Communication & Industrial Wireless 

1. Application

5G small cells, industrial wireless access points, CPE, industrial modems, and private LTE/5G network nodes.

2. Key Requirements

• Ultra-Wide Output Voltage Range:Different hardware platforms operate at different nominal voltages. A broad continuous output range reduces SKUs and streamlines inventory management.
• Sustained Power:These nodes run continuously under varying radio loads. The supply must maintain a stable output without a voltage droop that could affect RF stability.
• Broad Certification Coverage: Deployments span diverse regulatory environments. Multi-certification on a single SKU simplifies global logistics.
• Resilience to Input Variation:Industrial facilities often have poor power quality. Wide input tolerance and transient suppression protect against grid anomalies.

3. Recommended Solution: UES90C-SPAZ

• This 90W unit boastsan 11–54V continuous output range supporting the entire spectrum of 5G small cells and industrial wireless hardware without voltage-specific variants.
• Featuring multi-region safety certifications, this ITE power supply adapter handles the input voltage variability typical of industrial installations.
• UES90C-SPAZachieves >100,000 hours MTBF per MIL-HDBK-217 at 25°C ambient temperature.

Server & Edge Data Center

1. Application  

Edge servers, industrial NAS systems, hyper-converged infrastructure nodes, AI inference appliances, and ruggedized computing platforms.

2. Key Requirements

• High Continuous Power Output:Edge servers sustain high CPU and storage I/O loads over extended periods. The power supply must deliver rated wattage without thermal derating under sustained load.
• Multi-Voltage Output Coverage:Different subsystems within the same chassis may require different rails. A wide selectable output range reduces internal conversion stages, improving efficiency.
• Energy Efficiency Level VI Compliance:Efficiency shortfalls across hundreds of edge nodes increase electricity consumption and cooling needs. Level VI is increasingly a procurement requirement.
• Reliability:Edge nodes operate in ambient conditions that vary widely. The power supply must sustain full performance without forced-air cooling.

3. Recommended Solution: UES300AZ-SPA

• UES300AZ-SPA sustains the output required for edge servers and industrial NAS platforms running intensive workloads.
• Its wide 19V–54V selectable output range spans mainstream storage and server hardware requirements, allowing a single configuration to serve multiple system designs.
• Certified to Energy Efficiency Level VI, the unit minimizes conversion losses, significantly reducing the thermal burden on uncooled edge enclosures.

Industrial Control & Automation 

1. Devices

PLCs, HMIs, industrial sensors, servo controllers, distributed I/O modules, and motion control systems.

2. Technical Requirements

• Multi-Voltage Compatibility: Factory floors utilize mixed control rails (12V, 24V, 48V, etc.). A single power supply platform offering multiple selectable output voltages significantly reduces SKU count, inventory costs, and qualification overhead.
• Global Safety Certification: Shipping automation platforms globally require a power unit holding comprehensive, simultaneous certifications (CB, TUV, NRTL, CE, FCC) to bypass region-specific hardware variants.
• Robust Noise Immunity:Heavy industrial grids generate severe electrical noise. The power supply must deliver tight output regulation and low noise emissions despite conducted interference from nearby motors and drives.

3. Recommended Solution: UES150C-SPAZ

• The UES150C-SPAZprovides eight selectable output voltages spanning 12V to 54V, covering the full range of control voltages encountered across modern industrial automation installations.
• Its MTBF rating of greater than 100,000 hours meets the reliability floor required for continuous industrial operation.
• Comprehensive, simultaneous CB, TUV, NRTL, CE, and FCC certifications enable a single SKU to serve global deployment programs without region-specific variants.

Industrial Lighting & Smart Building Systems 

1. Devices 

LED driver power supplies, access control panels, HVAC control units, and smart metering infrastructure.

2. Technical Requirements

• High Fixed Output Voltage:Directly interface with LED driver architectures. A mismatch here forces additional DC-DC conversion stages that add cost, reduce efficiency, and introduce additional failure points.
• Compact, Enclosure-Friendly Form Factor:Building control cabinets and lighting distribution panels are strictly space-constrained.
• ITE Safety Certification:Smart building infrastructure must comply with commercial installation standards. Certification to IEC 62368-1 is a baseline requirement for regulatory approval in commercial and industrial projects.

3. Recommended Solution: UES140DZ-SPA

The UES140DZ-SPA supplies 140W at a fixed 54V output — a voltage level that interfaces directly with LED driver inputs and BMS power rails without requiring intermediate DC-DC conversion, preserving system efficiency and reducing component count.

Its compact form factor is sized for direct integration into building control cabinets and lighting distribution enclosures, and ITE safety certification covers the compliance requirements of commercial and industrial building installation projects.

Conclusion
