Custom, semi-custom, and field-proven switch-mode power conversion products engineered for continuous operation in mission-critical applications worldwide.
For over 40 years, ABSOPULSE Electronics Ltd has designed and manufactured thousands of heavy-duty, industrial-grade power supply solutions at our purpose-built 80,000 sq ft facility in Ottawa, Ontario, Canada. Our solutions are deployed in every operational environment—from underground mines and offshore vessels to high-voltage substations and extreme climate control cabinets.
Unlike commercial power supplies designed for controlled indoor facilities, ABSOPULSE industrial power conversion units are built with generous design headroom, conservative thermal derating, robust component selection, and superior physical protection to resist electrical transients, wide temperature swings, dust, humidity, salt spray, and mechanical shock.
We provide full-spectrum electrical design flexibility to meet precise input rails, regulated output rails, physical footprints, and cooling constraints.
Isolated step-down, step-up (boost), and wide input range DC-DC converters built for heavy industrial environments, rail transportation, and battery backup systems.
Universal input and active PFC rectifiers, industrial battery chargers, and single/multi-output switch-mode power supplies engineered for extreme reliability.
Microprocessor-controlled pure sine wave inverters delivering clean 50Hz, 60Hz, or 400Hz output for sensitive automation and utility control hardware.
Scalable 19-inch and 23-inch power assemblies featuring plug-in Eurocard modules, N+1 redundancy, load sharing, and comprehensive alarm monitoring.
ABSOPULSE power conversion systems operate reliably inside OEM machinery, remote field enclosures, and transport fleets worldwide.
Continuous-duty power supplies for factory automation, robotic arms, material handling systems, CNC machinery, and high-vibration process control equipment.
Substation-grade power conversion, phase/frequency converters, and high-voltage DC-DC converters for hydro, wind, solar, nuclear, and grid transmission infrastructure.
Fully sealed IP66-rated power supplies and encapsulated converters built to resist conductive dust, moisture, intense vibration, and washdown spray in underground and surface mining.
Onboard power converters for commercial electric vehicles (EV), hybrid transit buses, trucks, and heavy-duty utility vehicles operating under wide thermal swings.
Shipboard sine wave inverters, ROV/AUV subsea power packs, deck machinery power supplies, and saltwater-resistant assemblies compliant with marine safety standards.
High-reliability rack-mount rectifiers, battery backup system chargers, and remote monitoring power units designed for continuous operation in off-grid field shelters.
We design and qualify power supplies to stringent international performance, safety, and electromagnetic compatibility (EMC) standards.
Designed to comply with major international standard frameworks including generic industrial safety regulations (EN, UL, CSA, IEC 62368-1, IEC 61010-1) and application-specific standards.
Our Ottawa facility features dedicated testing setups for formal CSA, UL, CE, and custom OEM qualification, ensuring smooth market entry for customer end-products worldwide.
Configurations available with full potting/encapsulation, conformal coating, heavy-duty chassis heatsinks, pure convection cooling, and die-cast IP66 water-tight enclosures.
