Explore our export-grade isolated switching power supplies, high-wattage converters, and intelligent battery chargers customized for high-humidity, grid-variable environments in Vietnam.
Vietnam has emerged as a powerhouse of global electronics manufacturing, smart logistics, automotive assembly, and renewable energy integration. Industrial hubs spanning Bac Ninh, Thai Nguyen, Hai Phong in the North to Binh Duong, Dong Nai, and Long An in the South are rapidly upgrading their manufacturing lines to Industry 4.0 standards. Central to this technological transformation is electrical system reliability. Modern Automated Guided Vehicles (AGVs), Programmable Logic Controllers (PLCs), Distributed Control Systems (DCS), Supervisory Control and Data Acquisition (SCADA) networks, and high-density surveillance arrays demand isolated power converters capable of protecting sensitive electronics against severe voltage transients, earth loops, and electromagnetic interference (EMI).
As a global OEM/ODM manufacturer specializing in switch-mode power supplies (SMPS), galvanic isolated DC-DC converters, and industrial battery chargers, our organization delivers heavy-duty power conversion hardware tailored to the unique operational realities of Vietnam’s industrial market.
Galvanic isolation physically and electrically separates the input circuit from the output circuit. Energy transfer occurs via electromagnetic induction through an isolated transformer core, coupled with optoisolated feedback loops. This architecture ensures that high-voltage surges, lightning strikes, or severe switching spikes occurring on the primary grid side cannot pass through to the low-voltage control electronics on the secondary side.
Unstable AC grid conditions in rural or rapidly expanding industrial zones across Vietnam frequently cause line sag, neutral shifting, and transient voltage spikes. Standard non-isolated buck or boost converters tie input and output grounds together. When a heavy inductive load (such as a 50kW motor drive or an arc welder) kicks back counter-EMF onto the common ground plane, non-isolated converters transmit these surges directly to PLC I/O modules, resulting in corrupted sensor signals, processor lockups, or permanent component breakdown.
Our line of industrial isolated converters incorporates high-frequency transformer isolation, active Power Factor Correction (PFC > 0.95), and conformal coating on all printed circuit boards (PCBs) to withstand salt mist, dust, and humid tropical climates.
Complete 3000VAC input-to-output dielectric isolation prevents ground loops and high-voltage spikes from destroying control electronics.
Engineered to maintain stable output voltage even during severe voltage drops or surges typical of unstable local utility grids.
Specially coated PCBs protect internal components against 95% relative humidity, moisture condensation, and industrial airborne pollutants.

Major international OEM assembly plants operating in Bac Ninh and Thai Nguyen require ripple-free DC power to feed automated optical inspection (AOI) machines and surface-mount technology (SMT) pick-and-place lines. High frequency switching noise from adjacent power equipment can introduce measurement errors in delicate sensor electronics. Our isolated DIN Rail SMPS units feature low output ripple and noise (< 100mVp-p), active EMI filtering compliant with EN55032 Class B, and zero downtime ride-through performance during micro-cuts in power.
Vietnam’s rapid adoption of electric mobility—led by domestic EV pioneers and expanding charging station networks—requires ruggedized DC-DC isolated converters. Installed within outdoor charging kiosks across highway corridors, these converters translate high-voltage battery storage levels down to isolated 12V or 24V control buses for billing terminals, touchscreen HMIs, and relay contactors, operating reliably at ambient temperatures up to 70°C with linear derating.
Under Vietnam’s National Power Development Plan 8 (PDP8), solar and wind power integration has accelerated across central and southern provinces. Solar inverter stations and Battery Energy Storage Systems (BESS) experience massive DC voltage swings and lightning surges. Our high-voltage isolated converters handle DC input ranges up to 1000VDC, providing secure auxiliary power to grid-synchronization controllers, environmental sensors, and motorized circuit breakers.
Container cranes and port logistics automation in Hai Phong and Da Nang operate in harsh salt-air environments. Standard open-frame power supplies corrode rapidly. Our fully enclosed aluminum case isolated power converters undergo salt spray testing and feature anti-corrosion conformal coatings, providing uninterrupted operation for maritime crane control units, RFID readers, and vessel tracking systems.
Built upon 30+ years of dedicated power electronics design and manufacturing expertise (Sanstar Microsystems / Micro Power), our facility combines stringent quality management systems with scalable production lines capable of supporting large-scale OEM contract projects in Vietnam.
Every single power supply unit undergoes 100% full-load elevated-temperature burn-in testing before shipment to guarantee zero-defect delivery.
