ABSOPULSE Electronics designs and manufactures robust 19-inch and 23-inch rack-mount power supply systems engineered specifically for mission-critical industrial, electrical utility, railway, mining, and telecommunications infrastructure. Built using modular Eurocard plug-in assemblies, these power shelves provide exceptional scalable capacity, hot-swappable convenience, and N+1 redundancy in demanding operating environments.
Whether your application requires custom AC-DC power supplies, high-voltage DC-DC converters, or pure sine wave DC-AC inverters, our engineering team tailors each sub-rack assembly to match exact electrical, thermal, and mechanical constraints. Designed, prototyped, and manufactured entirely in-house at our 80,000 sq. ft. Ottawa facility, every system reflects over 40 years of power engineering excellence.
Our Eurocard plug-in modules can be configured in parallel or independent output topologies, featuring full electrical isolation, advanced circuit protection, and comprehensive monitoring options.
Modules feature internal isolation diodes and plug-in blind-mate connectors, allowing seamless hot-swappable replacement during live operation without system downtime.
Combine AC-DC rectifiers, battery chargers, DC-DC step-up/down converters, and DC-AC inverters within a single 3U or 6U sub-rack to power diverse industrial loads.
Configurable with front-panel AC/DC breakers, load distribution fuses, analog/digital metering, Form-C fault alarms, and battery low-voltage disconnect (LVD).
Options range from fan-free pure convection cooling with external heatsink fins to forced-air assemblies with field-replaceable heavy-duty fan filters.
Sub-racks are designed to fit standard 19-inch or 23-inch EIA electronics racks, with specialized mechanical chassis available for tight vehicular or marine space envelopes.
Engineered to withstand heavy shock, vibration, thermal cycling, and electrical transients in accordance with IEC, EN50155, and MIL-STD standards.
The table below summarizes standard platform parameters. Every modular rack system is customizable for specific input voltage rails, load profiles, and output specs.
