Highly resilient step up-down voltage converters designed to survive offshore salt fog and maintain precise voltages on high-discharge automated guided vehicle systems.
As Northern Europe's leading logistics metropolis and home to the third-largest container port in Europe, Hamburg is rapidly transitioning toward automated, climate-neutral operations. From the automated container terminals at Altenwerder (CTA) and Burchardkai (CTB) to offshore wind substations in the German Bight and marine vessel retrofits, reliable low-voltage power conversion is critical. Fluctuations in battery and grid lines pose constant threats to onboard computers, sensor arrays, and terminal radio equipment.
Our industrial-grade step up-down (buck-boost) DC-DC converters are uniquely suited to the harsh maritime and industrial environments of Hamburg. By employing advanced topology designs, our converters automatically adjust voltages, whether the input supply drops during high motor startup draws or surges during regenerative braking. This ensures reliable operation for AGVs, tugboats, crane control boxes, and offshore sensor networks.
Exploring the high-efficiency components, thermal management protocols, and safety profiles that distinguish our products in critical industrial sectors.
Traditional non-isolated buck-boost converters rely heavily on Schottky diodes, resulting in forward-voltage drops that lower overall efficiency. Our converters utilize high-speed, low RDS(on) MOSFETs controlled via microcontrollers. This reduces heat dissipation, extends battery life, and ensures operating efficiencies up to 96% even under full load conditions.
We use high-thermal-conductivity organic silica gel potting compounds. Combined with cast aluminum finned heat-sinks, our design prevents internal hotspots. Heat is evenly distributed and dissipated, preventing thermal runaway and eliminating the need for noisy, failure-prone mechanical cooling fans.
Industrial machinery in Hamburg's ports frequently generates high voltage transients. Our step up-down converters incorporate multi-stage protection networks, including Transient Voltage Suppressors (TVS), common-mode noise filters, and over-current/short-circuit protection arrays designed to meet ISO 7637-2 specifications.
Our converters maintain a tight voltage output regulation band (±1%) across wide input variations (such as 8V to 40V, or 18V to 40V). This is ideal for 12V and 24V applications where load changes cause voltage drops in battery systems.
Specially engineered for vehicle electronics in trucks and vessels, our converters feature a dedicated ACC terminal. This allows the system to boot up or shut down alongside the main vehicle ignition, preventing standby battery drain.
Designed with Hamburg's eco-sensitive ports in mind, our converters focus on minimized standby idle currents (under 10mA) and are certified lead-free under RoHS directive 2011/65/EU, reducing environmental footprint.
Leveraging the world's most robust electronics supply chain in Shenzhen to deliver precision power electronics to Germany with uncompromised quality.
Shenzhen Wemaxpower Technology Co., Ltd. has spent over 7 years refining design topologies, sourcing channels, and testing procedures for programmable DC power supplies, DC-DC buck-boost converters, and modular power bricks. Operating from Shenzhen, the global hub of electronics hardware engineering, we source components from tier-one manufacturers to guarantee reliability.
Our production pipeline combines high efficiency with strict European quality compliance. By establishing long-term supply agreements for critical raw materials (such as high-grade magnetic cores, low-impedance capacitors, and specialized automotive chips), we maintain pricing stability and deliver fast lead times, shield our clients in Germany from industrial supply bottlenecks.
Our commitment to quality is highlighted by our 4-Step Quality Control process. We verify performance metrics at each stage of manufacturing to ensure every shipped unit functions reliably under challenging conditions.
We check active and passive components, verifying magnetic core permeability and MOSFET performance to prevent defects prior to board assembly.
Automatic Optical Inspection (AOI) inspects components post-reflow, checking solder joints and gate signals under partial loads.
We test every finished converter for output range, line/load regulation, protection thresholds, and ripple noise.
Each unit undergoes a 100% full-load thermal burn-in aging test in heated chambers, weeding out early failures before packaging.
Select from our certified range of step up-down voltage regulators. Featuring high protection ratings, efficiency, and safety profiles for European applications.
Exporting power electronics to Germany requires strict adherence to EU regulations and German industrial norms. At Shenzhen Wemaxpower, we provide complete documentation and testing to streamline importing through the Port of Hamburg or Hamburg Airport customs terminals.
All our step up-down DC-DC converters carry CE marks and comply with Electromagnetic Compatibility (EMC) Directive 2014/30/EU and Low Voltage Directive (LVD) 2014/35/EU. Additionally, we use RoHS-compliant, lead-free materials to align with WEEE directives in Germany. Our supply chains offer flexible shipping options, including express air freight for urgent project integration and ocean cargo containers for volume orders, ensuring your factory lines operate smoothly.

Answers to common design and deployment questions concerning industrial buck-boost systems in logistics and marine environments.
Standard buck or boost converters only convert voltages in one direction. A step up-down (buck-boost) converter handles input voltages that fluctuate both above and below the target output. For example, in 24V marine battery systems, high starting currents can drop voltages to 18V, while battery charging can push them to 30V. A buck-boost converter stabilizes these inputs to a steady 24V without power interruptions.
Our housings are cast from a high-density anodized aluminum alloy, completely back-filled with a high-purity thermal epoxy compound. This potting process seals out all oxygen, dust, moisture, and corrosive salts. It prevents electrochemical degradation on internal PCB tracks and enables the units to operate reliably under high vibrations, such as on port machinery and vessels.
High-frequency switching power supplies can generate electromagnetic noise. Our designs mitigate this by using high-frequency, low-loss toroidal inductors and multi-stage LC filters on both input and output stages. Metal shielding layouts on our multi-layer PCBs block radiative coupling, helping you meet European EN 61000 industrial emissions regulations.
