Engineered for high immunity, rigorous thermal cycling, and continuous duty. Compare our flagship industrial power supplies and DC-DC conversion hardware tailored for OEM integrators.
Known as Norway's innovation capital and maritime nerve center, Trondheim hosts world-leading ocean laboratories, autonomous shipping trials in Trondheimsfjorden, and high-latitude aquaculture facilities. Standard off-the-shelf power converters inevitably fail when confronted with saltwater ingress, extreme thermal swings (-40°C to +70°C), and continuous galvanic galvanic stress. Our custom OEM waterproof DC-DC converters bridge the reliability gap.
In autonomous surface vessels (ASVs) and autonomous underwater vehicles (AUVs) deployed from Ny-Ålesund to Trondheim harbor, battery bus dynamics fluctuate violently. Lithium Iron Phosphate (LiFePO4) and NMC battery banks swing between 42V and 58.8V during heavy thruster loading. Zhejiang Harlon Electronic Co., Ltd. designs wide-input (18–75VDC and 200–800VDC) buck, boost, and isolated bidirectional topologies vacuum-encapsulated in thermally conductive epoxy. These provide galvanic isolation exceeding 3,000Vrms, fully shielding delicate sensor payloads, acoustic doppler current profilers (ADCP), and Nvidia Jetson-based neural computer vision banks from voltage dips and transient inductive back-EMF.
Sealed IP68 subsea converter modules capable of operating inside nitrogen-purged atmospheric chambers or non-conductive dielectric oil baths. Ideal for powering sub-surface multibeam sonar, hydraulic thrusters, and autonomous oceanographic floats navigating sub-zero North Sea depths.
Exposed open-ocean fish farms outside Hitra and Frøya rely on DC microgrids driven by hybrid diesel-battery-solar arrays. Our anti-corrosion anodized aluminum converters withstand airborne chloride mist, delivering ripple-free 12V, 24V, and 48V power to automated pellet feeders, biomass cameras, and oxygenation telemetry.
Trondheim Havn's green maritime initiative demands high-efficiency auxiliary DC-DC conversion for electric tugboats, hybrid ferries, and shoreside shore-power energy storage systems (BESS). We supply units featuring integrated CAN bus telemetry, programmable voltage trimming, and active surge damping.
Understanding regional compliance mandates and environmental challenges gives our OEM partners a competitive technical advantage in EU and EFTA tenders.
Procurement teams in Trondheim require strict adherence to maritime conducted immunity (EN 60945) to prevent VHF/GPS jamming. Our custom filters suppress high-frequency ripple under 30mVp-p.
Maritime electric drivetrains are consolidating on high-voltage DC distribution. Harlon engineers customized step-down modules converting 600V–850VDC down to clean 24VDC instrument control power without intermediary bulky transformers.
Condensation caused by crossing the Arctic Circle creates rapid dew point collapse inside standard cabinets. Total encapsulation in self-healing PU resin eliminates moisture intrusion, salt crusting, and mechanical vibration degradation.
Norwegian engineering buyers favor hardware with verifiable longevity. Backed by MTBF calculations exceeding 350,000 hours (MIL-HDBK-217F) and 100% full-load burn-in screening, our converters lower total operational expenditure (OPEX).
