Explore our certified flagship DC conversion modules, high-precision I/O controllers, and heavy-duty power supplies engineered for industrial off-highway and telematics integration.
In modern industrial automation, off-highway electrification, and telematics systems, power conversion is no longer a simple step-down function. It represents a vital control point for thermal stability, electromagnetic compatibility (EMC), and network diagnostic telemetry.
Off-highway equipment, heavy-duty mining machines, and commercial electric vehicles expose power conversion electronics to extreme electrical stress. Fluctuations in alternator supply, load dump transients up to 100V, cold-cranking voltage dips down to 6V, and intense thermal cycling require custom OEM DC-DC converters to incorporate advanced topology selection and robust component derating.
Standard commercial off-the-shelf (COTS) power supplies fail when subjected to continuous 20G mechanical vibration or corrosive salt spray. Custom OEM engineering bridges this gap by integrating ceramic potted enclosures, planar transformers, aluminum metal-core circuit boards (MCPCB), and custom firmware tailored specifically to vehicle bus control protocols like SAE J1939 and CANopen.

Our custom DC-DC converter platforms utilize high-frequency switching topologies and wide-bandgap (WBG) semiconductors to achieve ultra-high power density and minimal thermal signature.
By implementing Gallium Nitride (GaN) and Silicon Carbide (SiC) switching elements, our custom converters operate at frequencies exceeding 500 kHz. This significantly reduces passive component volume, enabling ultra-compact form factors while maintaining efficiency above 96% across varied load profiles.
Unlike conventional static converters, our intelligent OEM power modules communicate directly via standard vehicle buses (SAE J1939, CANopen, or Modbus RTU). Equipment operators receive real-time monitoring of input/output current, internal operating temperature, fault alerts, and software-configurable voltage output.
Engineered to meet ISO 16750, SAE J1455, and MIL-STD-810G standards. Modules feature IP67/IP69K sealed polyurethane or silicone potting compounds, providing complete protection against submersion, thermal shock, dust infiltration, and extreme vibration in heavy mining and agricultural equipment.
Full optical and magnetic isolation up to 3000V DC prevents ground loops and protects sensitive microprocessor controls from high-voltage spikes caused by inductive solenoid switching or motor drive back-EMF, strictly adhering to ISO 7637-2 pulse transient standards.
Reduce inventory SKUs with programmable output voltage and current limits. OEM procurement teams can deploy a single unified converter platform across multiple equipment lines, adjusting operating parameters during factory flashed assembly or via remote over-the-air (OTA) updates.
With calculated MTBF (Mean Time Between Failures) exceeding 500,000 hours under full industrial loading, our custom converters virtually eliminate costly field downtime and warranty replacements in high-capital industrial assets.
Understanding shifting global engineering requirements helps procurement officers and engineering executives future-proof their supply chain and machine architectures.
Driven by zero-emission mandates in urban construction and agricultural equipment, OEMs are migrating from traditional 12V/24V architectures to 48V and 800V DC bus networks. This shift minimizes cable harness weight and resistive losses ($I^2R$). Consequently, demand is surging for dual-directional step-down/step-up converters capable of bridging high-voltage traction batteries with 12V auxiliary electronic control units (ECUs).
Modern fleet operators expect predictive maintenance capability. OEM buyers no longer accept isolated "dumb" power supplies. Modern RFQ specifications mandate integrated SAE J1939 messaging capability, enabling real-time telemetry streaming of thermal health, power consumption profiles, and localized over-voltage diagnostic codes directly to central telematics gateways.
Recent global semiconductor bottlenecks underscored the vulnerability of single-source proprietary power modules. Modern procurement strategies prioritize OEM manufacturing partners offering modular pin-compatible platforms designed with automotive-grade, non-proprietary component topologies that insulate against long component lead times.
As off-highway cabs integrate sensitive high-frequency GPS, LiDAR, dynamic inclinometers, and radar sensors, radiated electromagnetic interference (EMI) from switching converters can cause system degradation. Advanced OEMs require converters compliant with CISPR 25 Class 5 and UN ECE R10 standards to guarantee zero interference with high-precision machine automation sensors.

Get fast, clear answers to essential technical and commercial questions evaluated by engineering leads and purchasing managers.
We offer full custom engineering covering hardware layout, enclosure dimensions, connector types (Deutsch, TE Ampseal, M12, Molex), input/output voltage windows (9V–140V DC), output wattage, dynamic load response, software protocol programming (SAE J1939, CANopen, Modbus), and custom potting compounds for specialized thermal/vibration environments.
Our custom DC converters incorporate multi-stage input filters, transient voltage suppression (TVS) diodes, and active over-voltage clamp circuits designed to surpass ISO 7637-2 and ISO 16750-2 automotive pulse standards. This prevents damage caused by battery disconnects, inductive load dump spikes, and electrostatic discharges (ESD).
Yes. Our engineering team specializes in CANbus embedded software development. We can program custom J1939 PGNs or CANopen Object Dictionaries into the converter’s microcontrollers, enabling real-time broadcast of operating voltage, current draw, internal temperature, and diagnostic error flags to your machine's primary Display ECU or Telematics Gateway.
Non-Recurring Engineering (NRE) costs depend on design complexity and testing compliance requirements. Rapid functional prototypes can typically be delivered within 8 to 12 weeks following specification sign-off. Alternatively, we can adapt pre-validated catalogue core platforms to significantly reduce NRE expense and shorten lead times to under 4 weeks.
Our manufacturing facility in Canada operates under an ISO 9001:2015 quality management system. Units are validated for thermal shock (-40°C to +105°C), 20G mechanical vibration (MIL-STD-202G / SAE J1455), IP67/IP69K ingress sealing, CE compliance, RoHS directive alignment, and CISPR 25 EMC radiated/conducted emissions limits.
We utilize high-thermal-conductivity potting media combined with heavy-copper multi-layer circuit boards and aluminum alloy heat-sink housings. This architecture efficiently transfers heat away from critical power MOSFETs, allowing continuous operation at full rated power without thermal derating in ambient temperatures up to +85°C.
