Voltmat Power
Engineered for absolute stability, high efficiency, and maximum protection in harsh industrial environments.
In the modern industrial landscape, electrical loads have evolved to be highly sensitive and dynamically demanding. Off-the-shelf power solutions frequently fall short when confronted with specialized applications—such as semiconductor processing, hydrogen electroplating, large-scale battery formation, telecommunications infrastructure, and high-precision laboratory testing. As a leading OEM/ODM custom power solutions manufacturer and supplier based in Shanghai, we bridge this engineering gap. We specialize in high-power regulated power supplies engineered to meet rigorous specifications, ensuring exceptional efficiency, minimal ripple, and uncompromising reliability.
Global industrial enterprises operate under distinct local grid standards, unique environmental conditions, and stringent safety frameworks. The primary driver for sourcing custom power systems lies in the failure of standard catalogue supplies to handle specialized workloads:
Applications like electroplating, electrolysis, and battery charging require dynamic adaptation. Standard supplies operate on narrow margins, whereas our solutions allow adjustment ranges from 24V up to 1000V, and wattages scaled up to 40,000W and beyond, supporting precise step-less adjustments.
Industrial installations are frequently subject to dust, chemical aerosols, high relative humidity, and temperature variations. Standard enclosures easily fail under these stresses. Custom engineering allows for sealed, conformal-coated PCBs, liquid cooling paths, or IP-rated active thermal management.
Smart factories rely on real-time telemetry. Standard analog control knobs are replaced or supplemented by custom isolated digital buses, such as RS-485, CAN bus, Modbus RTU, or Ethernet interfaces. This enables seamless PLC integration for remote diagnostic monitoring and safety shutoffs.

Operating out of Shanghai, the industrial heartland of Eastern China, provides strategic operational benefits for our global procurement partners. Shanghai represents a nexus of advanced electronics fabrication, raw material availability, and highly optimized export pathways.
Being based in Shanghai allows us to coordinate direct shipments via Shanghai Port (the world’s busiest container port) or Shanghai Pudong International Airport (PVG). This infrastructure dramatically reduces domestic transport times, simplifies customs protocols, and minimizes inland shipping vibrations that can affect calibrated electronics.
The Yangtze River Delta houses an unparalleled concentration of component suppliers—ranging from specialized high-frequency magnetic core wound-transformer producers to semiconductor developers. This proximity enables us to source top-tier, custom-spec passive and active components rapidly. As a result, design iterations are faster, and lead times for high-capacity projects are reduced.
Our decade-and-a-half focus on industrial voltage regulation ensures that our design, firmware, and thermal layouts are built on mature, field-tested foundations. We have optimized topologies to resist electromagnetic interference (EMI) and power grid surges, guaranteeing an exceptionally low return rate and long product lifecycles.
Every single custom power unit is subjected to dual-phase automated and manual diagnostic testing before shipping.

Our quality validation follows a dual-layered approach. First, automated computerized testing verifies thousands of parameters, mapping transient responses, voltage drift, line regulation, and load regulation. Second, manual diagnostic verification by seasoned quality engineers inspects wiring harnesses, soldering points, structural integrity, and physical insulation.
This is backed by specialized equipment, including AC Withstand Voltage Testers to confirm galvanic isolation up to 3000V AC, and Constant Temperature & Humidity Chambers to simulate harsh operation profiles. Only after passing these rigorous tests does a power supply receive its individual serial number and shipping approval.
A truly premium power supply must conform to regional standards and adapt to localized application constraints. We customize physical enclosures, electrical interfaces, and internal architectures to meet specific geographical requirements:
We build systems to operate seamlessly on single-phase 110V/220V or three-phase 380V/480V AC distribution networks. Active Power Factor Correction (PFC) circuitry is standard on high-power models, ensuring compliance with strict EN61000 harmonics regulations.
For installations in offshore, marine, or highly humid environments, custom power supplies feature conformal coatings (Class I Div 2 standards), marine-grade stainless steel enclosures, and specialized vibration isolators.
To reduce electrical noise in laboratory and precision test benches, our designs incorporate robust EMI filters and isolated high-frequency switching designs. These measures prevent line feedback and protect adjacent measurement gear.
To prevent transport-induced damage, every unit is packaged following a strict multi-layer protocol:
As power demands increase, modern topologies must deliver higher power density and integration capabilities:
