ABSOPULSE Electronics offers an extensive range of industrial and railway-grade DC-DC power converters designed to operate reliably where off-the-shelf commercial power supplies fail. Utilizing advanced switch-mode topologies, our converters deliver exceptionally high efficiency, compact physical dimensions, and robust electrical protection.
Whether your application requires stepping down high line DC voltages, stepping up battery rails, or establishing complete galvanic isolation between DC buses, ABSOPULSE covers output power requirements from 5W to over 30kW. All units are housed in heavy-duty metal enclosures engineered for mechanical stability and severe operating conditions.
Our power conversion systems are specified globally by original equipment manufacturers (OEMs), system integrators, power utilities, railway rolling stock builders, and mining operators across North America, Europe, Asia, and worldwide.
Every industrial installation presents unique electrical, thermal, and mechanical challenges. ABSOPULSE adapts standard proven platforms to match your exact project parameters.
Standard and custom input rails including 12Vdc, 24Vdc, 36Vdc, 48Vdc, 72Vdc, 96Vdc, 110Vdc/125Vdc, 250Vdc, and ultra-high input voltages up to 1200Vdc with transient immunity.
Single, dual, or multiple regulated output rails (3.3V, 5V, 12V, 15V, 24V, 48V, 125V, 250Vdc or custom voltages) with tight line and load regulation and minimal ripple noise.
Conformal coating options for high humidity and atmospheric contamination, full encapsulation/potting for maximum vibration tolerance, and IP66 die-cast enclosures.
Internal decoupling diodes enable N+1 redundancy and active current sharing for high-power system integration, fault-tolerant infrastructure, and mission-critical backup.
Built with conservatively derated components to withstand ambient operating temperatures from -40°C to +70°C without derating, utilizing convection, conduction, or fan cooling.
Engineered to meet EN62368-1 (formerly EN60950-1), UL/CSA safety guidelines, EN50155 railway standards, IEC61373 shock/vibration compliance, and RoHS environmental rules.

The LTH 65R-F3-HSA series features heatsink assembly fins for pure fan-free convection cooling in high-reliability battery step-up tasks.
PDC 400-P400 modules provide complete immunity against extreme shock, vibration, thermal stress, and dust contamination.
BAP 319-D4G series housed in sealed die-cast aluminium IP66 enclosures to withstand severe washdown and outdoor environments.
We supply converters covering standard industrial and transit DC voltages including 12V, 24V, 36V, 48V, 72V, 96V, 110V/125V, and 250Vdc. We also design specialized high-voltage input converters capable of accepting up to 1200Vdc continuous input for utility and traction equipment.
Yes. Our DC-DC converters can be equipped with conformal coating, full encapsulation (potting compound), or IP66 die-cast aluminium enclosures. These options protect sensitive electronics against conductive dust, water jets, corrosive fumes, humidity, shock, vibration, and operating temperatures from -40°C to +70°C.
Yes. ABSOPULSE manufactures an extensive line of railway-grade DC-DC converters designed specifically to satisfy EN50155 requirements for electronic equipment used on rolling stock, including wide input voltage tolerance, surge withstand, immunity to shock/vibration (IEC61373), and fire/smoke compliance.
Absolutely. Because all prototyping, metal fabrication, component assembly, and testing are performed in our Ottawa, Canada facility, we can easily adapt mounting footprints, connector types, mechanical envelopes, and thermal management methods to match your exact system architecture.
