Voltmat Power
Premium featured switching power supplies configured for Portugal's strict grid requirements and high electrical standards.
As Portugal positions itself as one of the leading green industrial and technological hubs in Western Europe, the requirements for large-scale energy conversion infrastructures have scaled exponentially. Bolstered by the National Energy and Climate Plan (PNEC 2030), industrial zones in Sines, Lisbon, Setúbal, and Porto are seeing major investments in sectors demanding highly precise, raw DC electrical power.
Operating heavy machinery, electroplating tanks, green hydrogen electrolyzers, and fast-charging EV charging networks requires a robust foundation. Our 40000W adjustable AC-DC power supplies are specifically engineered to interface with Portugal's three-phase 400V grid, delivering stable, isolated, low-ripple direct current up to 1000V. Standard commercial power modules cannot safely sustain the continuous thermal loading required at these thresholds. A dedicated, industrial-class 40kW system is required, offering protective galvanic isolation and active power factor correction (PFC).
Procuring 40kW+ power conversion systems internationally presents major challenges for European engineers. The common pain points are strict regulatory oversight (such as CE compliance, low harmonic distortion requirements, and EMC limits) and physical product reliability.
When purchasing from outside the EU, buyers need assurance that their supplier possesses advanced technical capabilities and understands target grid tolerances. In Portugal, voltage consistency must remain stable under dynamic loading conditions. A system that experiences high switching noise or drops out under rapid thermal shifts is unusable. By using high-frequency switching technology with premium magnetic components, our power supplies deliver an efficiency rate of 88-89%, reducing heat generation and ensuring compliance with the electromagnetic standards required by EU factories.
Our state-of-the-art facility located in Shanghai combines modern automated precision with expert engineering checks. We utilize advanced component sourcing, ensuring that key semiconductor parts like IGBT modules and fast recovery diodes are selected for thermal resilience.
Operating from a 10,000 square meter factory, our workflow integrates modern automated soldering and potting machinery with extensive human inspection. Every single 40kW unit undergoing production is subjected to a dual-testing protocol: an automated computer simulation to record input-output dynamics, followed by an intensive 24-hour heat-chamber aging run supervised by quality technicians. This strict procedure ensures a 99.9% factory qualification rate, minimizing field failures.

A transparent look at our specialized production processes, ensuring electronic integrity from initial component cutting through assembly and moisture-proof packaging.
Each system is shipped via standardized export routes. Prior to dispatch, units are treated with moisture-proof packaging to protect internal components during ocean transport, surrounded by high-density polyethylene shock absorption material, placed into specialized protective cardboard cases, and finally fixed with reinforced outer wooden frames to guarantee pristine condition upon arrival.
How our heavy duty and switching systems operate under practical Portuguese manufacturing environments.
A major supplier of battery management assemblies located in the Braga region required high-power simulation capabilities. Using our 20KW-24KW High Voltage DC Supply, they successfully simulated fast charging states up to 800V, evaluating high-current stress on safety cut-offs and relays.
An experimental green hydrogen setup in Sines utilized our 40000W adjustable switching power supply. Providing pure isolated direct current, the project achieved steady gas evolution rates while assessing grid disturbances from incoming solar energy fluctuations.
Deploying our 400V-6000W adjustable switching power supplies to simulate high energy electric fields. High accuracy levels permit researchers to study advanced polymer breakdown metrics under strict laboratory parameters.
