Engineered with IP67/IP68 aluminum casings, robust galvanic protection, and high power conversion efficiency for local Portuguese OEMs and systems integrators.
Navigating the demand for robust isolated power conversion in Central Portugal's technological capital.
Coimbra is actively modernizing its public transportation ecosystem, led by the SMTUC (Serviços Municipalizados de Transportes Urbanos de Coimbra) and regional electric mobility initiatives. High-voltage battery systems (operating across 36V, 48V, 72V, and 80V nominal DC architectures) require high-reliability isolated DC-DC converters to step down voltage safely for auxiliary electronics, telemetry units, digital displays, and onboard CAN-bus communication modules without risks of ground loops or chassis noise contamination.
Home to the renowned University of Coimbra (FCTUC), iParque (Coimbra Innovation Park), and the Instituto Pedro Nunes (IPN), the region serves as a epicenter for advanced robotics, biotech automation, and industrial IoT startups. Industrial facilities situated in Pedrulha and Taveiro require IP67/IP68 sealed DC-DC regulators capable of operating under strict electromagnetic compatibility (EMC) standards to prevent high-frequency switching interference in sensitive research instruments.
In industrial regions like the Mondego Valley, localized voltage fluctuations, common-mode ground noise, and high humidity pose severe challenges to DC power supplies. Non-isolated buck converters allow electrical noise and potential high-voltage surges to pass directly from the primary battery or solar bus to low-voltage control microcontrollers. Galvanic isolation creates a physical magnetic gap, ensuring operational reliability, protecting sensitive telemetry, and eliminating costly system downtime.
A comprehensive examination of topology selection, planar magnetics, thermal management, and noise immunity for European system designers.
Our isolated converter modules utilize push-pull and forward-flyback topologies operating at high switching frequencies (200kHz to 400kHz). This architecture enables compact planar transformers that achieve dielectric breakdown ratings exceeding 1500VDC to 3000VDC, protecting delicate low-voltage microprocessors (5V, 12V, 24V) from primary high-voltage spikes (up to 150VDC).
Designed for severe ambient conditions found in outdoor solar installations and heavy machinery, each unit is encapsulated in thermally conductive polyurethane silicone compound within an extruded aluminum shell. This guarantees an IP67 or IP68 waterproof rating while providing passive cooling capable of operating reliably from -40°C to +85°C.
To meet European Union directive standards (CE marking, EN 55032 Class B for radiated and conducted emissions), our isolated DC regulators integrate multi-stage LC filters and shielding frames. This ensures zero interference with nearby radio frequency communications, GPS tracking units, and precision agricultural sensors.

Shenzhen Wemaxpower Technology Co., Ltd. stands as a premier manufacturer of high-performance power conversion equipment. With over 7 years of specialized engineering in programmable DC power supplies, step-down DC-DC isolated regulators, and custom power modules, we deliver reliable solutions to global markets.
Our direct manufacturer model allows OEMs and integrators in Coimbra and across Portugal to bypass multi-tiered regional markup, securing factory-direct pricing, custom voltage tailoring, and rapid sample prototyping within 7-10 working days.
Customized power regulation solutions addressing specific operational demands across municipal, agricultural, and industrial installations.
Electric buses operating across Coimbra’s steep urban terrain demand steady 12V and 24V auxiliary power from main 48V or 80V traction battery packs. Our IP67 waterproof isolated converters drive onboard passenger counting systems, ticket validation terminals, and LED destination signs while effectively shielding sensitive electronics from motor voltage transients.
Agricultural monitoring stations along the Mondego river valley rely on off-grid solar PV panels and battery storage (nominal 24V/48V). Wemaxpower isolated buck modules convert variable solar voltages to steady 5V or 12V DC power for soil moisture sensors, automated drip irrigation valves, and remote telemetry transmitters.
Technological ventures and automated light manufacturing plants located in iParque deploy isolated DC-DC converters to decouple heavy motor actuators from delicate PLC control boards. This prevents ground loops and eliminates system reboots triggered by electromagnetic noise during heavy inductive load switching.
Remote telecommunication towers across Central Portugal utilize high-voltage solar arrays (80V-150V DC). Our wide-input isolated converters efficiently step down high DC voltages to 5V, 12V, or 24V DC to supply backup routers, cellular repeaters, and environmental monitoring hardware.
Explore our full range of CE-approved, high-efficiency voltage step-down modules tailored for Portuguese industrial procurement.
Key technical criteria, regulatory compliance, and Total Cost of Ownership (TCO) evaluation for European engineering buyers.
When selecting a converter for automotive or solar battery systems, nominal voltage is only a starting point. High-performance units must accommodate broad operating ranges (e.g., 36V-48V inputs operating continuously from 30V to 60V DC) to withstand back-EMF spikes during heavy motor braking or sudden solar irradiance changes.
Importing power supplies into the European Union requires compliance with Low Voltage Directive (LVD) and EMC Directive standards. Wemaxpower isolated converters are manufactured under ISO 9001 certified processes, bearing authentic CE marking and RoHS compliance documentation for frictionless customs clearance into Portugal.
Industrial applications in Coimbra demand maintenance-free operation over extended operational lifespans. Our products undergo rigorous thermal shock testing and component derating, achieving MTBF ratings exceeding 500,000 hours under standard operating conditions.
Addressing key technical, logistical, and commercial inquiries from system integrators in Coimbra and global buyers.
An isolated DC-DC converter utilizes a high-frequency transformer to separate the input and output ground lines electrically (galvanic isolation). A non-isolated converter shares a common ground wire. Isolation prevents high-voltage spikes, ground loops, and electrical noise from damaging sensitive load electronics on the low-voltage side.
Coimbra experiences variable climatic conditions with elevated humidity in the Mondego River basin and dust in industrial zones like Pedrulha. IP67 and IP68 aluminum potting protects internal circuitry from moisture ingress, vibration, and dust, ensuring continuous outdoor operation.
