Engineered for high power density, wide voltage operational tolerance (90–290VAC), and continuous 24/7 mission-critical operations across Vietnam's automated manufacturing zones.
The Hanoi metropolitan area—extending through critical industrial corridors such as Bac Ninh, Thai Nguyen, Hai Phong, and Hung Yen—has rapidly evolved into Southeast Asia’s premier high-tech manufacturing, semiconductor assembly, and consumer electronics production cluster. Supported by national initiatives under Vietnam Industry 4.0 and the national Power Development Plan 8 (PDP8), local system integrators, panel builders, and plant engineers are undergoing a massive transition toward automated smart manufacturing.
However, operating electronic production lines in Northern Vietnam introduces distinct technical challenges for power supply equipment:
As a specialized Switching Power Supply Manufacturer & OEM Factory Partner serving the Hanoi market, our engineering division (developed under the legacy of Sanstar Microsystems / Micro Power) designs and delivers heavy-duty power supplies, DIN-rail SMPS, DC-UPS backup modules, and industrial battery chargers specifically tropicalized and ruggedized for Northern Vietnam’s operational landscape.
Discover how our switch-mode topologies overcome severe local power quality anomalies to maintain unyielding operational continuity.
Engineered with active Power Factor Correction (PFC > 0.95) and wide-range primary magnetics, our SMPS units sustain continuous, ripple-free regulated DC output even during dramatic grid voltage sags common in regional Vietnam industrial parks.
Every printed circuit board assembly undergoes double-pass acrylic or silicone conformal coating. This protective layer shields surface-mount components against high humidity, conductive dust, airborne chemical pollutants, and mold growth in tropical factory environments.
Eliminate line-drop system reboots. Our 24V DC-UPS units seamlessly transition to battery power with zero transfer time (0ms switchover), protecting mission-critical PLCs, industrial PCs, edge robotics, and security head-ends.

With three decades of power electronics design expertise, our manufacturing operations supply tailored AC-DC switchers, battery chargers, and DC power packs to key sectors throughout Greater Hanoi:
Automated assembly lines, surface-mount technology (SMT) pick-and-place machines, and robotic arms rely on our 24V DC DIN-Rail Power Supplies (NDR-480 series) and diode OR-ing redundancy modules. By maintaining strict voltage regulation within ±1%, our units protect delicate microcontrollers and servo drives from high-frequency electrical noise.
Traffic monitoring networks, urban elevated rail systems (such as the Cat Linh – Ha Dong metro line), and commercial real estate security systems require continuous low-voltage DC power. Our 30mm Slim 75W 12V SMPS and DC Power Packs with Battery Backup ensure that IP cameras, PTZ domes, and NVR recording equipment remain fully operational even during grid interruptions.
Standby power generators in mission-critical facilities like data centers, hospitals, and telecom towers in Hanoi require intelligent battery charging. Our 60W SMPS cum Battery Charger (UL Certified) features automatic float/boost dual-stage charging, deep discharge cut-off protection, and potential-free alarm contacts to maintain engine-start battery health indefinitely.
High-voltage transmission substations managed by Vietnam Electricity (EVN) across Northern Vietnam deploy our industrial battery chargers and high-voltage DC-DC converter modules to power Vacuum Circuit Breakers (VCB), protection relays, and SCADA remote terminal units (RTUs).
Under Vietnam's PDP8 energy mandates, industrial facilities must reduce parasitic electrical losses. Our latest switching supplies achieve up to 94% conversion efficiency with active PFC correction (>0.98), minimizing heat dissipation inside enclosed control cabinets.
As industrial backup systems migrate from traditional Sealed Lead-Acid (SLA) to Lithium Iron Phosphate (LiFePO4) chemistries, our customized OEM battery chargers integrate customizable charging profiles, CC/CV algorithms, and cell balancing telemetry.
Sanstar Microsystems / Micro Power brings over 30 years of specialized power conversion engineering. Our state-of-the-art manufacturing infrastructure is managed under rigid ISO-compliant quality protocols, delivering key competitive advantages:
Get immediate, authoritative answers regarding specs, delivery, customization, and local grid compatibility.
Our industrial SMPS series feature an ultra-wide AC input range of 90VAC to 290VAC with dynamic primary feedback control. When the local grid sags during peak summer usage, our primary switching circuits automatically adjust duty cycles to keep the DC output perfectly regulated at nominal voltage without thermal overload.
Yes. All power supply orders destined for Vietnam can be specified with thick-layer IPC-CC-830 certified acrylic or silicone conformal coating. This protects all surface-mount components, transformer pins, and solder joints against moisture condensation, high ambient humidity, and corrosive atmospheric elements.
Depending on the product family, our power supplies carry UL508 (Industrial Control Equipment), CE EMC/LVD compliance, BIS certification (IS 13252), and FCC Class B ratings. Detailed test reports and Declaration of Conformity (DoC) certificates are provided for OEM export documentation.
Standard catalog models are stocked for rapid dispatch. Custom OEM/ODM requests (such as specialized mechanical housing, custom voltage taps, or dual-charging logic) take 2 to 3 weeks for prototype validation and 4 to 6 weeks for full-scale volume production delivery to Hanoi ports or industrial parks.
A standard AC UPS converts DC battery power back to AC, which the panel SMPS then converts back to DC—causing 20-30% energy loss and adding battery degradation risks. A DC-UPS connects directly to the 24V DC bus, delivering 0ms transfer time, higher total efficiency (>95%), and a significantly smaller physical footprint inside control cabinets.
Absolutely. Our 60W UL-Certified SMPS cum Battery Chargers and heavy-duty charger series are built specifically for engine-start applications. They feature automatic float-to-boost charging mode switching, reverse polarity protection, and potential-free fault output signals compatible with standard AMF and BMS controllers.
Whether you require standard DIN-rail units, custom OEM multi-rail power supplies, high-current battery chargers, or tropicalized DC-UPS systems, our application engineering team is ready to assist your project.
