Engineering Excellence

Tailored Power Conversion Built for Severe Operating Environments

Continuous industrial operation demands robust electrical architecture. Wall Industries partners directly with OEM design teams to deliver high-efficiency custom power conversion systems that resolve space restrictions, power surge vulnerabilities, and extreme thermal conditions.

Proven Industrial Power Expertise

Since 1961, Wall Industries has designed and manufactured custom power solutions in Exeter, New Hampshire, USA. Industrial and commercial machinery operates under harsh duty cycles where standard off-the-shelf power modules often fail. Our engineering team utilizes field-proven circuit topologies—such as LLC resonant converters, active PFC front-ends, forward, and flyback architectures—to ensure your power design meets exact operational specifications without unnecessary cost overhead.

Whether your application requires high-efficiency switching designs, wide-range DC inputs, multi-rail outputs, or specialized ruggedized enclosures, we provide end-to-end design verification, compliance pre-testing, and prototype manufacturing to keep your project timeline on schedule.

Modifications vs. Ground-Up Custom Engineering

Most industrial equipment challenges can be solved rapidly via a modified-standard design. By altering output voltage trims, adding conformal coating, customizing cable wiring harnesses, or upgrading thermal baseplates on standard platform modules, engineering lead times and regulatory compliance expenses are significantly reduced.

For complex applications demanding unique form factors, multi-phase inputs, or specialized thermal management, our team engineers fully custom power systems from original concept to high-volume manufacturing, ensuring compliance with UL 62368-1, UL 508, CE, RoHS, and REACH directives.

Proven Field Performance

Custom Industrial Engineering Case Studies

Real-world power engineering solutions developed for complex industrial manufacturing and automated infrastructure.

Precision Automated Screwdriver Assembly

Challenge: A hand-held assembly tool manufacturer required a lighter, highly compact power module to fit a strict ergonomic enclosure requirement without sacrificing continuous power output.

Solution: Wall Industries converted the existing heavy linear power supply design into a compact, high-frequency switching power supply. The new architecture delivered a significant reduction in overall weight and size while dramatically boosting operating efficiency.

Water Purification & Chlorination Equipment

Challenge: Commercial water treatment installations experienced frequent power module failures under heavy continuous workloads and damp operational conditions.

Solution: Wall replaced unreliable legacy linear units with custom-engineered, fully potted switching power supplies featuring enhanced thermal dissipation and moisture isolation, exceeding client uptime targets.

Conveyor Automation & Material Handling

Challenge: High-volume warehouse conveyor systems suffered catastrophic power supply failures triggered by frequent utility power outages and subsequent voltage switching surges.

Solution: Wall engineers developed a custom 480 VAC 3-Phase input power supply integrated with Limited Power Source (LPS < 100W) ratings, active surge protection, and built-in redundancy to guarantee 24/7/365 uninterrupted operation.

Quality & Accountability

Why Global OEM Procurement Teams Trust Wall Industries

Rigorous Design Verification

Every custom design undergoes extensive thermal profiling, EMI pre-compliance testing, and stress testing under worst-case load conditions before full-scale manufacturing release.

Strict Component Traceability

Our strict counterfeit-parts prevention policy and robust supply-chain risk mitigation ensure long-term availability for capital equipment with multi-decade product lifecycles.

Direct OEM Engineering Support

You work directly with US-based power conversion engineers throughout the design process, from original electrical specification to qualification and production.

Technical FAQ

Frequently Asked Questions on Custom Industrial Power Supplies

Modified-standard prototypes are typically delivered within 4 to 8 weeks depending on component availability and customization scope. Fully custom ground-up engineering projects generally take 12 to 16 weeks from initial specification sign-off to functional prototype delivery.

We integrate robust transient voltage suppression (TVS), MOV networks, passive/active filtering, and wide input-voltage tolerance windows (such as 4:1 DC inputs or 480V 3-phase AC inputs) to ensure uninterrupted power delivery despite harsh grid spikes.

Yes. We specialize in conduction-cooled designs using metal baseplates, heat-sinks, high-efficiency switching topologies, and thermal potting materials that allow heat to dissipate directly through system chassis walls without requiring forced air ventilation.

Yes. We engineer form-fit-function replacement power supplies for obsolete OEM equipment, allowing industrial operators to maintain infrastructure longevity without undergoing expensive complete system overhauls.
