Safety, power density, and continuous thermal performance are integral to every AC/DC power supply engineered by Wall Industries.
Full-range AC input capabilities (85–264 VAC and 90–305 VAC) ensure smooth operation across worldwide main power grids without manual selector switches.
Comprehensive electrical protections including continuous short-circuit protection (SCP), over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown guard against load faults.
Engineered to satisfy key safety and electromagnetic compatibility standards, including UL/IEC 62368-1 for ITE/industrial equipment, IEC 60601-1 for medical devices, and CISPR32/EN55032 Class B EMI limits.
Industrial-grade power supplies built with premium components operate reliably across wide temperature ranges from -40°C to +70°C (+85°C derating), ideal for unconditioned environments.
High conversion efficiency topologies minimize wasted heat, meeting DoE Level VI and EU CoC Tier 2 requirements for standby power consumption and energy savings.
Input-to-output isolation ratings up to 3,000 VAC – 4,000 VAC (2xMOPP) ensure robust galvanic isolation for safety-critical patient proximity medical devices and sensitive controls.
From operating rooms to automated factory floors, Wall Industries customizes power designs to meet sector-specific environmental and regulatory mandates.

US-Based Engineering Heritage
Standard catalog models do not always align with unique OEM enclosure constraints, input surge mandates, or custom thermal environments. At Wall Industries, our engineering facility in Exeter, New Hampshire has designed and modified AC/DC power converters since 1961. We leverage proven switching topologies—flyback, forward, LLC resonant, and active PFC front-ends—to accelerate development while eliminating risk.
Choosing a modified-standard AC/DC supply allows OEM design engineers to modify existing qualified designs for custom output voltage trims, specialized wiring harnesses, potting compounds, or conformal coating. This path preserves foundational safety test data while delivering a form-fit-function match for your device.
For fully custom power supply programs, our senior power design team collaborates directly with your engineering group. We evaluate input bus fluctuations, peak load profile requirements, isolation clearance, cooling geometry, and target safety compliance prior to prototype production.
Whether your equipment requires operation in extreme temperatures (-40°C to +85°C), zero-fan silent conduction cooling, or compliance with specialized military or medical directives, Wall Industries provides rigorous design verification, pre-compliance testing, and sustained multi-year production support.
Over 60 years of power conversion engineering experience, delivering reliable power supplies across aerospace, defense, healthcare, and industrial markets worldwide.
Robust design validation, high-reliability component selection, 100% burn-in testing, and comprehensive traceability across all production batches.
We actively support long capital equipment lifecycles, offering continuous production availability and form-fit-function replacements for legacy AC/DC power supplies.
Our AC/DC power supplies feature universal AC input voltage capability, typically supporting standard 85–264 VAC line inputs as well as extended industrial ranges up to 90–305 VAC (120–430 VDC). Line frequency compatibility ranges from 47Hz to 63Hz, making them ideal for worldwide power grids.
Wall Industries supplies AC/DC power solutions in encapsulated PCB mountable modules, ultra-compact open frame circuit designs, U-channel packaging, ventilated high-power enclosed chassis with optional cooling fans, 35mm DIN rail enclosures, and external desktop or wall plug-in adapters.
Yes. Many of our AC/DC power supply series comply with international medical safety standards including ANSI/AAMI ES60601-1 and IEC/EN 60601-1 3rd Edition. They provide 2xMOPP (Means of Patient Protection) isolation, low isolation capacitance, and ultra-low leakage current engineered for patient-connected medical instruments.
Our AC/DC units integrate continuous auto-recovery short circuit protection (SCP), over-voltage protection (OVP), over-current/over-load protection (OCP/OLP), line transient filtering, and thermal shutdown to guard against system field failures.
Yes. If standard catalog parameters do not meet your mechanical envelope, pinout, voltage trim, or environmental requirements, our engineering team in Exeter, NH can provide modified-standard or ground-up custom AC/DC power supply designs tailored to your OEM specification.
