Voltmat Power
Engineered to support Greek manufacturing, marine electrification, and utility-scale solar-to-storage facilities.
As Greece undergoes a massive structural change driven by the **National Energy and Climate Plan (NECP)**, sectors ranging from maritime shipping electrification at the Port of Piraeus to heavy steel industries in the Attica and Central Macedonia regions require unprecedented electrical modernization. The rapid integration of variable renewable energy sources (especially utility-scale solar PV in Thessaly) creates a paramount demand for highly reliable, large-scale industrial rectifiers and power converters to stabilize local grids and microgrids.
For critical applications such as **green hydrogen electrolysis**, **high-power EV charging hubs**, and **industrial surface treatment**, voltage stability and harmonics control are vital. Standard commercial converters fail to withstand the high ambient temperatures of Southern Europe and the voltage sags common in remote industrial zones. This is where our **20000W - 24000W AC/DC switching power supplies** provide a robust technical foundation, delivering stabilized 24V to 1000V DC outputs under continuous, harsh duty cycles.
• Strict EU Harmonized Standards conformity.
• Sea-air environment protection for coastal industrial plants and port infrastructure.
• Demand for energy-efficient solutions (88-89% dynamic efficiency) to mitigate high EU industrial electricity costs.
Our high-power supply topology features an advanced **Phase-Shifted Full-Bridge (PSFB)** DC-DC converter combined with active power factor correction (PFC) circuitry. By leveraging silicon carbide (SiC) Schottky diodes and high-performance IGBT switches, these units significantly minimize switching losses while operating stably within Greece's 3-phase grid infrastructure (380V/400V/415V).
Designed with a wide-range adjustable output capability (options spanning 24V up to 1000V DC), these supplies support multi-mode current/voltage operations, enabling automated integration with Siemens, ABB, and Schneider PLC controllers through Modbus or analog programming interfaces.

Equipped with active Power Factor Correction (cos φ ≥ 0.99), protecting localized Greek distribution grids from disruptive harmonics (THD < 5%) in heavy motor start-ups.
With major shipyards in Syros, Elefsina, and Skaramangas, our power supplies utilize conformally coated PCBs and sealed cooling fans to guard against salt spray corrosion and humidity.
Robust cooling manifolds combined with smart thermal throttling keep the systems operational in peak Greek summer temperatures (+45°C ambient) without power derating.
Operating from our state-of-the-art **10,000 square meter facility in Shanghai**, we bring 15 years of singular focus in high-power regulated DC power systems. Every 20kW-24kW unit is built using lean manufacturing principles and automated assembly processes.
To ensure zero-downtime integration at remote Greek operations, every power supply undergoes **two independent rounds of inspection**: a fully automated digital signature diagnostic run followed by a 24-hour manual burn-in test at maximum thermal stress. The result is a factory-proven **99.9% qualification rate** upon arrival.
**Sea & Air Logistics Protection:** Heavy industrial electronic components are extremely sensitive to vibration and moisture during transit. We encapsulate all systems in heavy-duty moisture-barrier vapor bags, fitted inside double-walled corrugated cartons with high-density polyurethane shock absorption inserts, completed by reinforced external wooden crates.
Select from our benchmark 20kW-24kW range - fully customizable outputs, protocols, and mounting standards.
Ensuring seamless installation, commissioning, and regulatory alignment in Greece.
Exporting power systems to the European Union demands strict compliance. Our 20000W-24000W platforms meet **CE (Conformité Européenne)** requirements, adhering to the Low Voltage Directive (LVD) **2014/35/EU** and the Electromagnetic Compatibility (EMC) Directive **2014/30/EU**. We provide complete declaration of conformity documentation, circuit diagrams, and thermal maps for immediate local authorization.
Based in Shanghai, we leverage prime access to Shanghai Port for direct ocean shipment routes to **Piraeus, Greece**. With established relations with major freight forwarders (COSCO, MSC), we offer DDP (Delivered Duty Paid) and CIF customs clearance support, shortening shipping transit times and handling all import tariff documentation smoothly.
Every industrial environment has unique configurations. Whether your Greek factory floor uses a customized rack-mount structure, analog control (0-5V / 0-10V / 4-20mA loop signals), or a digital bus protocol (RS485 / Modbus RTU / CANopen), our Shanghai design team can tailor the internal firmware and I/O interface to fit your legacy setup.
