High-efficiency, stabilized single-output units customized for Northern Vietnam's advanced assembly, testing, and automated processing plants.
Analyzing the critical role of precision power management systems in structural upgrades within global electronics ecosystems.
Northern Vietnam, centered around Hanoi and neighboring provinces such as Bac Ninh, Bac Giang, and Hai Phong, has emerged as a premier global hub for electronics manufacturing. As corporate giants relocate fabrication lines and assembly complexes to Vietnam, the local demand for specialized high-power DC sources has scaled significantly. In facilities operating surface-mount technology (SMT) setups, high-precision automated testing, semiconductor component packaging, and specialized electroplating, stability is paramount.
The electrical grid in industrial parks requires robust compensation. High-frequency ripples or microsecond voltage sags can compromise delicate silicon wafers or interrupt multi-million dollar testing lines. Custom-designed 1500W-2000W AC/DC switching power supplies, supporting wide-range output profiles from 12V to 600V, act as critical buffers, delivering highly-regulated, clean DC power with low electromagnetic interference (EMI) profiles.
Beyond Southeast Asia, the global industrial sector is undergoing a rapid transition toward electrification and smart factory configurations. High-power AC/DC converters in the 1.5kW to 2kW range serve as fundamental components in advanced electric vehicle (EV) charging stations, telecom server arrays, aerospace simulation systems, and green hydrogen electrolysis lines.
Modern procurement mandates demand efficiencies exceeding 88%-89%, low standby losses, and compatibility with international input voltages (50/60Hz, 110V/220V/380V). Global sourcing teams require partners capable of combining rapid design turnarounds, competitive manufacturing costs, and strict compliance with global electrical safety frameworks.
Our state-of-the-art 10,000 square meter production facility is strategically located in Shanghai, China’s industrial and technological hub. This location enables rapid access to premium magnetic components, semiconductor switches, advanced PCB materials, and specialized IC solutions. For procurement departments in Hanoi and internationally, our location facilitates efficient logistics via direct air freight from Pudong International Airport or container shipping from the Port of Shanghai directly to Haiphong Port, minimizing transit risks and lead times.
By integrating a highly skilled engineering team and a mature component supply chain, we deliver custom-engineered AC/DC power supplies at competitive prices, without compromising on thermal management, component lifetime, or safety features.

How our design parameters address tropical environments, wide voltage requirements, and safety demands.
Hanoi’s sub-tropical climate experiences high relative humidity levels, which can reach 85% to 90% during summer months. In industrial sites that are not fully air-conditioned, humidity combined with ambient dust can compromise electric insulation, leading to breakdown arcs and leakage currents. Our custom series addresses this with two key measures:
Our 1500W-2000W AC/DC models feature dual-sided acrylic conformal coating on all logical control layers. High-power components (inductors and output diodes) are potted with high-conductivity silica glue, offering complete moisture isolation, mechanical stability, and efficient heat transfer directly to the extruded aluminum casing.
Instead of continuous ventilation, our systems utilize internal microcontrollers to regulate fan speed based on real-time heat sink temperatures. This minimizes internal dust accumulation and extends the lifespan of our heavy-duty ball-bearing fans in dusty automation workshop environments.
For procurement managers exporting finished equipment or upgrading production lines, having fully certified equipment is critical. Our industrial DC converters are built to align with CE (LVD/EMC), FCC Part 15 Class A, and RoHS standards, incorporating several standard protection features:

Access technical solutions and support parameters compiled by our team of applications engineers.
Our industrial high-power supply units operate with an efficiency profile of 88% to 89% when loaded between 50% and 90% capacity. By implementing active soft-switching topology (such as phase-shifted full-bridge switching) and reducing secondary rectification losses, we minimize heat generation, translating to lower thermal dissipation demands in industrial racks.
Yes. Many models support built-in active current-sharing control circuits, allowing parallel installation to increase total output current. For series connections designed to boost voltages up to 1200V DC, external blocking diodes must be installed to protect secondary components against reverse-bias spikes. Please specify parallel or series requirements when ordering.
Our units are designed to withstand fluctuations in input supply lines. Equipped with wide-input Active Power Factor Correction (PFC) stages, they operate reliably with input ranges spanning 180V to 264V AC, maintaining high power factors (>0.95). In regions prone to sag or surge sequences, integrated metal oxide varistors (MOVs) and fast-acting fuses absorb transient voltage spikes.
High-voltage models incorporate multi-stage LC filters on output lines, keeping peak-to-peak ripple voltages within 1% of the rated nominal output (e.g., less than 4Vp-p for a 400V DC module). This level of control is suitable for noise-sensitive testing environments, telecom base stations, and high-precision electroplating machinery.
Our standard warranty is 1 year from the date of receipt, covering all mechanical and electrical failures under normal operational guidelines. In the event of a warranty claim, our engineering team in Shanghai conducts diagnostics via video link. Replacement modules or entire replacement units are dispatched directly via express couriers to minimize downtime.
We apply a four-tier logistical protection design. The base unit is sealed in a moisture-barrier bag, surrounded by custom-molded high-density polyethylene foam corner protectors. It is then placed in heavy-duty cardboard boxes, and reinforced with export-grade wooden framing to protect transformer windings and mechanical components during sea or air transit.
