Engineered by Zhejiang Harlon Electronic Co., Ltd. for extreme duty cycles, continuous thermal endurance, and rapid integration into Greater Boston industrial systems.
From maritime salt fog lingering across Massachusetts Bay to severe freeze-thaw cycles along Route 128 tech corridors, electrical installations in Greater Boston face stringent thermal and environmental demands.
Naval telemetry, commercial fishing electronics, and container crane sensors at Conley Terminal demand sealed galvanic isolation. Our waterproof DC-DC converters feature hermetically potted silicon elastomeric resin (thermal conductivity >1.8 W/m·K) to withstand ASTM B117 salt fog corrosion without dielectric tracking or moisture creep.
IP68 Submersible / Salt Spray ProtectedBoston's aggressive transit electrification drives continuous retrofitting of heavy bus and service vehicle auxiliaries. Step-down conversion from 48V/72V/96V traction batteries to 12V/24V instrumentation requires broad input voltage tolerance, transient suppression against load dump spikes, and immediate sub-zero cold start functionality.
-40°C Cold Start / Wide Dynamic V_inAutonomous mobile delivery robots, outdoor agricultural rovers, and coastal oceanographic inspection ROVs engineered in Cambridge and Waltham need dense, vibration-resistant power topologies. SMT-stabilized internal componentry guarantees continuous operation under 5G rms random vibration without mechanical fracturing.

Analyzing key legislative mandates, cleantech investments, and municipal infrastructure evolutions shaping procurement decisions for New England systems designers.
The City of Boston's net-zero carbon strategy mandates the electrification of all light-duty municipal vehicles and commercial fleets. This has triggered massive demand for rugged DC-DC converters capable of handling auxiliary loads from lithium-ion traction systems with zero parasitic drain during extended winter parking.
<1mA Ultra-Low Standby DrainRising sea level initiatives across the Seaport District, East Boston, and Charlestown demand that smart-city telemetry, flood gate actuators, and battery energy storage system (BESS) control electronics survive periodic tidal immersion. Standard open-frame power supplies are rapidly being phased out in favor of IP68 potted blocks.
Hermetic Ingress ProtectionWith major developments staged through the New Bedford Marine Commerce Terminal and support offices in Boston, offshore wind logistical vessels and meteorological buoys require rugged DC bus step-down converters with extensive galvanic isolation (up to 3000VAC) to mitigate high ground potential differences.
3000VAC Dielectric IsolationGreater Boston's biopharma hubs employ automated guided vehicles (AGVs) in cold-storage cleanrooms down to -30°C. Power converters must resist internal condensation during rapid transit between cleanroom chambers and ambient warehouse docks while strictly controlling conducted emissions.
EN 55032 Class B Low EMICombining 18+ years of dedicated switching power supply manufacturing with ISO 9001 quality infrastructure and SGS on-site factory verification.
Our automated two-component dispensing machines eliminate voids, air bubbles, and micro-fissures in polyurethane and epoxy resin matrices. This guarantees absolute thermal conductivity to the extruded casing and zero dielectric breakdown under extreme moisture or hydrostatic pressure.
Every single power unit passing through our Wenzhou facility undergoes full-load high-temperature burn-in cycles in dedicated environmental chambers. Early-life semiconductor failures are screened out before export packaging, yielding field failure rates below 0.15%.
Our engineering testing facility contains dedicated lightning surge generators, EMI receivers, hi-pot testers, and vibration testing tables. We guarantee electromagnetic compatibility according to EN 55032 and immunity to industrial transient surges per IEC 61000-4-5 standards.
Everything systems integration engineers, hardware purchasing managers, and logistics directors need to know about specifying, ordering, and validating our waterproof converters.
Standard industrial power supplies often suffer from cold-start failures due to electrolytic capacitor ESR (Equivalent Series Resistance) spikes at sub-zero temperatures. Harlon’s cold-climate DC-DC converters utilize premium solid polymer capacitors and custom silicone potting compounds rated down to -40°C (-40°F), preventing cold-cracking, dielectric collapse, or delayed startup during New England nor'easters.
Our IP67 models are certified to withstand water ingress when temporarily submerged up to 1 meter for 30 minutes, ideal for vehicle undercarriages, outdoor LED signage, and washdown panels. Our IP68 units undergo continuous submersion testing at depths exceeding 2 meters and are engineered for maritime hulls, wet well lift stations, and subsurface conduit infrastructure across Boston Harbor.
Yes. Zhejiang Harlon specializes in OEM/ODM customization. We frequently manufacture custom step-up and step-down ratios (e.g., 48V to 13.8V, 72V to 24V, 24V to 5V) and supply pre-molded wiring harnesses with Deutsch DT series, Amphenol, M12 circular, or SAE connectors to streamline high-volume assembly lines for Massachusetts robotics and vehicle builders.
We support versatile incoterms including FOB, CFR, CIF, EXW, and DDU. High-priority engineering prototypes and pre-production evaluation batches can be dispatched via air freight directly into Boston Logan International Airport (BOS) in 5 to 8 business days. Production volume orders ship via ocean freight container consolidated directly to the Port of Boston or Port of New York/New Jersey with complete customs documentation.
Our standard power supplies and converters are designed in alignment with UL 62368-1, UL 508A, CE, and RoHS directives. In-house EMI shielding rooms and conducted emissions receivers ensure our power stages easily satisfy FCC Part 15 Class B limits, protecting sensitive RF communications on municipal transit buses and precision bio-analytical equipment.
Every commercial production batch is accompanied by comprehensive Quality Control Inspection Reports, including incoming raw material verification, automated optical inspection (AOI) records, 100% full-load burn-in certificates, dielectric withstand (hi-pot) test data, and RoHS material declarations.
Whether evaluating standard S-Series switching modules or requesting bespoke IP67/IP68 DC-DC converter prototypes, our engineering department provides rapid feasibility reviews, thermal derating analyses, and transparent OEM price structures within 24 hours.
