ABSOPULSE Electronics Ltd designs and manufactures an extensive portfolio of high-reliability switch-mode DC-DC converters engineered for long-term operational integrity. Operating since 1982 out of our 80,000 sq. ft. facility in Ottawa, Canada, our engineering team specializes in surviving severe field environments including high thermal stress, intense shock/vibration, exposure to conductive moisture, salt fog, and broad line voltage swings.
The field-proven configurations listed below represent standard baseline platforms covering power levels from 50W to 5000W+. Because over 80% of our production output involves custom or modified power conversion systems, our engineering department quickly modifies input/output voltage combinations, mechanical chassis footprints, IP-rating protections, and thermal management schemes (pure convection, conduction baseplate, forced air, or liquid cooling) to meet exact OEM project requirements.
Engineered for automation, heavy machinery, power generation utilities, underground mining, and telecommunications installations. Designed for maximum MTBF using field-tested circuit topologies, conservative component derating, and high-grade thermal interfaces.
Built for extreme environments with exposure to dust, sand, humidity, and high mechanical shock. Completely potted with thermally conductive compound in rugged aluminum enclosures.
