About ABSOPULSE Electronics Ltd.
Welcome to ABSOPULSE Electronics

Founded in 1982, ABSOPULSE Electronics Ltd. is an original equipment manufacturer (OEM) specializing in the design, development and manufacture of high-reliability, heavy-duty switch-mode power conversion products for the railway, automotive, industrial automation, power utility, mining, marine and telecommunications sectors.

We are located on the outskirts of Ottawa in Canada’s ‘Silicon Valley North’. All of our products are designed and built in our 83,000sq foot custom-built production plant. Since inception, ABSOPULSE has grown steadily, and currently employs 120 people. The company is privately owned.

Rugged, Reliable

Reliability is engineered into every ABSOPULSE power supply. This ensures a long operating life with minimum maintenance under exacting field conditions and contributes to low product life-cycle costs.

Our stringent standards and processes encompass:
  • High quality designs with large design headroom;
  • Optimal thermal performance - all heat generating components are conduction cooled by heat-sink blocks connected to the base-plate;
  • Full electronic protection including surge and transient protection;
  • High efficiency;
  • High quality components with reliability established over many years;
  • Very high MTBF ratings supported by field data;
  • Robust mechanical construction;
  • Rigorous testing of every power supply throughout the production process - all units must pass ‘burn-in’ before shipment;
  • ABSOPULSE's quality procedures have been approved by international agencies and by our corporate customers;
  • The company is BABT approved and is able to provide in-house CSA, UL and other approvals.

Design Capabilities

Over the past 34 years, ABSOPULSE has developed thousands of power supply designs that are constantly proven in the field. We can often meet customer requirements by making a few modifications to standard designs. However, our primary focus is on providing custom solutions. Our engineering design and production teams work side-by-side in the same location, which facilitates the process of new product development. An extensive R&D program ensures that we are able to deliver solutions to customer requirements.

Mechanical Designs

Whatever the space constraints of your application, we will ensure that our ruggedly constructed power supplies meet your exact mechanical requirements.

Standard mechanical packages and ruggedization options include:
  • Chassis-mountable units in vented conduction/convection or fan-cooled enclosures;
  • DIN-rail and open-frame format available for many designs;
  • Plug-in (Eurocard) format for modular power systems in 19 inch or 23 inch racks;
  • Conformal coating and heavy ruggedizing;
  • Full encapsulation (potting) in a thermally conductive MIL-grade silicon rubber compound with
  • UL94V-0 flammability rating where immunity to very high levels of shock and vibration, humidity, moisture, dust, oil, fog, insects and other contaminants is required;
  • Enclosure in rugged NEMA/IP-rated packages;
  • Custom connections.
