Over 60 years of US-based engineering excellence delivering over 3,000 active standard catalog models and thousands of modified/custom designs.
Save time and re-qualification costs. We quickly adapt existing baseline models with specialized pinouts, cable harnesses, custom output voltages, or conformal coating.
Engineered in compliance with UL/IEC, MIL-STD, and EN regulatory frameworks with full lot traceability, counterfeit prevention, and ISO-aligned quality systems.
Wall Industries offers standard, modified-standard, and ground-up fully custom power supply designs. Our design team in Exeter, New Hampshire evaluates your electrical (voltage, current, ripple, isolation), mechanical (dimensions, thermal dissipation, connectors), and environmental specifications to build high-performance power units tailored to your exact form-factor and safety standard requirements.
A modified-standard power supply starts from an existing, safety-certified catalog platform and modifies specific features such as output voltage trimming, wiring harnesses, ruggedized potting, extended operating temperature derating, or special enclosure coatings. This approach significantly reduces initial NRE engineering costs and speeds up project compliance verification.
Our power supplies are designed to comply with key global safety standards, including UL/IEC 60601-1 (3rd & 4th Ed, 2xMOPP) for medical devices, MIL-STD-1275, MIL-STD-461, MIL-STD-810 for military systems, EN 50155 for railway transit equipment, CISPR 32 / EN 55032 Class B for radiated EMI, and DoE Level VI / EU CoC Tier 2 efficiency regulations.
Yes. We specialize in serving industrial and defense OEMs with long product lifecycles (10–20+ years). We maintain strict configuration control and offer form-fit-function replacements for obsolete power units from third-party manufacturers to prevent customer redesigns.
Speak directly with our applications engineering team. We assist global procurement managers and hardware design engineers in selecting, customizing, and qualifying power supplies for mission-critical applications.
