Serving Da Nang's High-Tech & Coastal Industrial Demands
From the manufacturing lines of the Da Nang Hi-Tech Park (DHTP) to the maritime infrastructure of Tiên Sa Port, our converters resolve the physical challenges of Central Vietnam's microclimates and automation architectures.
Da Nang Hi-Tech Park & SMT Fab
Precision electronics, IoT component assembly, and testing laboratories inside DHTP demand ripple-free DC buses. Our 1500V galvanically isolated DC-DC converters isolate high-frequency ground loops, ensuring signal integrity across automated SMT testing rigs and delicate microcontroller test equipment.
Tiên Sa & Liên Chiểu Port Logistics
Heavy container-handling cranes, automated guided vehicles (AGVs), and 48V–80V electric terminal tractors operating along Da Nang’s deep-water ports suffer from dirty power rails. Our synchronous step-down modules handle 100V transient spikes while maintaining locked 12V and 24V outputs for radar, weighing nodes, and cabin communications.
Marine & Offshore Aquaculture
Operating out of Thọ Quang fishing port and offshore Central Vietnam waters exposes power units to high-salinity humidity. Our IP68 sealed, epoxy-potted buck-boost converters and LiFePO4 battery-to-battery chargers resist salt-spray crusting, powering sonars, VHF communication arrays, and auxiliary LED night trawling rigs without electrolytic degradation.
Resort Shuttles & Urban Micromobility
Da Nang’s coastal tourism strip along Mỹ Khê beach utilizes electric shuttles, golf carts, and e-bikes. These 48V, 60V, and 72V traction battery architectures require high-amperage 12V conversion for telematics, lighting, and GPS trackers. Eltrum converters prevent parasitic battery drain and resist heat buildup under tropical ambient conditions.
Central Vietnam Solar Energy Storage
Da Nang's rapid adoption of industrial rooftop photovoltaic arrays across Hòa Khánh and Hòa Cầm Industrial Zones requires reliable balance-of-system power supplies. Our wide-input 10V–60V buck-boost regulators provide uninterruptible 24V DC control power to SCADA gateways, inverters, and battery management systems (BMS).
Industrial Telecom & Base Stations
Remote wireless relay points on Sơn Trà Peninsula and cellular sites across Central Vietnam rely on -48V DC power grids. Eltrum's isolated DC-DC modules convert negative and floating telecom inputs into stabilized +12V or +24V rails, preventing system downtime during lightning transients and utility transitions.
Selecting the Correct Conversion Topology
Proper power topology design eliminates system failure rates in tropical, coastal environments. Review the electrical tradeoffs between Buck, Boost, Buck-Boost, and Galvanic Isolation for your system architecture.

| Synchronous Boost | 10.5V – 16V / 18V – 28V DC | 24V, 36V, 43.8V, 48V | 92% – 95% | Boosting 12V alternator/battery systems to run 48V pumps, marine haulers & lithium packs. |
| Dynamic Buck-Boost | 8V – 40V / 10V – 60V Wide | 12V, 19V, 24V, 28V | 91% – 94% | Voltage stabilization for systems subject to cranking sag and solar load fluctuations. |
| Transformer Isolated | 18V – 36V / 36V – 75V Telecom | 5V, 12V, 24V (Regulated) | 88% – 92% | Ground-loop isolation in automated test benches, telecom sites, and positive-ground equipment. |
Da Nang DC-DC Market Trends & Strategic Vectors
As Da Nang progresses towards its mandate as a Smart Green City and Tier-1 Industrial Hub by 2030, power architecture specifications are shifting toward higher density, ruggedization, and intelligent telemetry.
Shift from Lead-Acid to LiFePO4
Da Nang's marine logistics fleets and tourist electric vehicles are rapidly phasing out lead-acid banks in favor of Lithium Iron Phosphate (LiFePO4). This transition necessitates CC/CV DC-DC charging modules that dynamically regulate alternator surges and avoid cell overcharge while operating inside hot battery enclosures.
Demand for IP67/IP68 Potted Modules
Standard open-frame or vented power supplies experience accelerated corrosion due to Da Nang’s seasonal monsoons and sea-salt mist. Modern engineering contracts within Hòa Cầm and Liên Chiểu industrial zones now universally mandate fully sealed, silicone or epoxy-potted housings that dissipate heat conductively.
IoT Integration & Digital Telemetry
Smart city infrastructure throughout Da Nang incorporates remote data aggregation. Plant engineers increasingly specify DC-DC converters equipped with RS485 (Modbus RTU) interfaces to monitor real-time output current, input voltage dips, and internal junction temperatures from central control rooms.
