ABSOPULSE Electronics Ltd. is a Canadian original equipment manufacturer (OEM) specializing in the custom engineering, design, and internal production of high-reliability, heavy-duty switch-mode power conversion products. Founded over four decades ago in Ottawa, Canada, ABSOPULSE has continuously expanded to become a recognized global leader in heavy-duty power supply design.
Our engineering capabilities encompass high-performance DC-DC converters, universal-input AC-DC power supplies, industrial battery chargers, pure sine wave DC-AC inverters, AC-AC phase and frequency converters, and complete 19-inch rack-mount power systems engineered for extreme industrial duty.
We address complex power conversion problems where off-the-shelf catalog units fail due to environmental extremes, high electrical noise, or demanding mechanical envelopes.
Every industrial power assembly engineered by ABSOPULSE is optimized for reliability, safety, and efficient thermal performance under severe operating environments.
Isolated step-down, step-up (boost), and bipolar power converters covering 5W to over 10kW. Feature wide DC input ranges, wide temperature operation, and high efficiency topologies.
Universal input switch-mode power supplies and heavy-duty industrial battery chargers up to 10kW+. Equipped with active Power Factor Correction (PFC) and temperature compensation.
Pure sine wave inverters and frequency converters delivering single-phase or 3-phase AC output at 50Hz, 60Hz, or 400Hz. Power ratings span 15VA to 10kVA with low total harmonic distortion (THD).
Scalable power supplies built from hot-swappable plug-in Eurocard modules. Engineered for N+1 redundancy, load sharing, remote monitoring, and complex utility control centers.
Immune to continuous moisture, dust, conductive oil, salt spray, and extreme shock. Sealed die-cast aluminium enclosures and potted modules engineered for mining, subsea, and washdown environments.
Flexible mechanical footprints including open-frame, DIN-rail mount, pure convection fins with heatsink assemblies, chassis-mount, and customized connector configurations.
High MTBF and minimum maintenance requirements directly lower total cost of ownership for long-term critical infrastructure projects.
Component stresses are strictly derated with generous thermal and electrical margins. High-reliability semiconductors and long-life capacitors are specified to ensure maximum field durability under continuous full-load operating conditions.
Heat-generating components are directly coupled to internal heatsink blocks and conduction baseplates. This allows fan-free, convection-cooled operation in dusty or sealed enclosures, eliminating mechanical fan failure points.
Full electronic protection is engineered into every unit, including input surge withstand, transient absorption, overvoltage protection, output current limiting, thermal shutdown, and short-circuit protection.
ABSOPULSE is a BABT-approved facility with full internal capability for CSA, UL, CE, and international agency approvals. Keeping testing and compliance in-house ensures rapid turnaround for custom client qualification requirements.
Every single power supply undergoes rigorous automated testing, functional validation, high-potential voltage withstand testing, and extended thermal burn-in before shipment to international clients.
Our power conversion units operate continuously inside rolling stock rail transport, power utility substations, underground mining equipment, subsea ROVs, oil & gas rigs, and industrial automation networks worldwide.
