Power Conversion Engineering
High-reliability AC/DC power supplies and DC/DC converters engineered for patient safety, clinical compliance, and zero-fault operation in demanding healthcare OEM equipment.
Wall Industries designs and manufactures medical-grade AC/DC power supplies (1W to 600W) and isolated DC/DC converters specifically engineered to protect patients and clinical operators. Backed by 60+ years of US power conversion engineering expertise.
In medical electronics, uncompromised safety and power stability are imperative. Wall Industries’ medical grade power supplies deliver clean, continuous, and regulated power to essential healthcare equipment—ranging from handheld patient diagnostic tools to complex surgical suites and hospital CT/MRI imaging systems.
All medical power platforms adhere to strict international safety frameworks, including IEC 60601-1 3rd/4th Edition, ANSI/AAMI ES60601-1, and CAN/CSA-C22.2 No. 60601-1. Incorporating dual Means of Patient Protection (2xMOPP) and ultra-low leakage current parameters, our power modules safeguard against electrical hazards in sensitive patient-connected environments.
Whether integrating open-frame or enclosed AC/DC units into diagnostic consoles, desktop adapters into portable therapeutic equipment, or miniature SIP/DIP PCB-mount DC/DC converters into floating patient monitoring circuits, Wall Industries provides fully certified standard catalog series and tailored modified-standard solutions.
Our engineering team works closely with OEM system designers to resolve challenging thermal constraints, electromagnetic interference (CISPR 11 Class B), high-altitude operation, and extended operational lifecycles required by long-term hospital deployment.

Powering mission-critical medical hardware in operating rooms, intensive care units, diagnostic laboratories, and home care environments.
Multi-parameter bedside monitors, ECG devices, blood pressure systems, and pulse oximeters requiring stable isolated DC rails and zero noise interference.
Infusion pumps, ventilators, anesthesia workstations, and surgical electrosurgical generators built for continuous duty and uninterrupted power delivery.
High-power imaging controls, portable ultrasound scanners, X-ray positioning logic, and CT/MRI subsystem power architectures.
Portable oxygen concentrators, sleep apnea CPAP machines, home dialysis systems, and battery-assisted mobility aids requiring Class II external adapters.
Blood analyzers, centrifuges, DNA sequencers, and automated diagnostic assay workstations demanding precise voltage regulation.
Oral imaging systems, dental handpiece controllers, surgical lights, and sterilization units built to withstand frequent cleaning cycles.
When off-the-shelf medical power supplies fail to satisfy your exact dimensions, thermal envelope, or pinout requirements, Wall Industries delivers modified-standard and custom-engineered power supplies. Our engineering team leverages qualified circuit topologies to accelerate qualification time while ensuring full compliance with IEC 60601-1.
Our custom capabilities include custom PCB layouts, specialized multi-output voltage rails, customized wire harnesses, potting for moisture and vibration protection, and custom metal chassis enclosures designed for seamless cabinet drop-in integration.
From initial design specification to prototype testing and final volume production, Wall Industries protects customer intellectual property and maintains complete product traceability. We assist medical equipment OEMs through design review, pre-compliance testing, and agency submission processes.
For applications demanding extended operational lifecycles (10–20+ years), we guarantee component longevity and support form-fit-function replacement strategies to prevent costly equipment redesigns.
Proven track record of supplying reliable power conversion hardware to world-class medical equipment manufacturers since 1961.
Designs rigorously evaluated for dielectric strength, creepage/clearance, thermal derating, and CISPR 11 Class B electromagnetic compatibility.
Maintained compliance documentation, rigorous counterfeit-parts prevention policy, and long-term production lifecycle guarantees.
Our medical power supplies are engineered and certified to meet international safety standards including IEC 60601-1 3rd/4th Edition, ANSI/AAMI ES60601-1, and CAN/CSA-C22.2 No. 60601-1. They satisfy 2xMOPP (Means of Patient Protection) and 2xMOOP (Means of Operator Protection) insulation criteria, as well as CISPR 11 Class B EMC limits.
MOOP (Means of Operator Protection) protects system operators from electric shock in clinical environments. MOPP (Means of Patient Protection) requires higher isolation dielectric strength (up to 4,000 VAC) and greater creepage/clearance distances (up to 8mm) to protect vulnerable patients who may be directly connected to electrical applied parts.
Wall Industries designs power units with stringent leakage current controls. Models intended for Type CF (cardiac floating) applied parts support patient leakage currents under 10µA in normal conditions and under 50µA in single-fault conditions, ensuring maximum safety for direct heart-contact equipment.
Yes. Most OEM design requests are resolved via modified-standard engineering. We can adjust output voltage trims, integrate custom cable harnesses or connectors, apply conformal coating or specialized potting, and tailor mechanical enclosures while keeping existing compliance certification pathways intact.
Both. Stationary medical equipment (such as diagnostic imaging machines, surgical tables, and lab analyzers) typically runs on AC mains power via internal open-frame/enclosed supplies or desktop adapters. Portable or battery-powered devices (such as patient monitors and defibrillators) utilize high-isolation DC/DC converters to step down battery voltages while maintaining patient isolation.
