Our ATEX/IECEx compliant power supply systems are built to endure thermal stress, electrical surges, high humidity, and explosive atmospheric hazards. Explore our standard and customizable conversion platforms designed for seamless integration into Spanish industrial control cabinets.
Spain’s industrial infrastructure is undergoing a massive dual transformation: expanding its world-class chemical and refining hubs while rapidly deploying green hydrogen, off-shore wind, and solar microgrids under the national energy strategy (PNIEC 2021–2030). In these demanding sectors, power supplies cannot be treated as commercial off-the-shelf commodities. They serve as the critical electronic bedrock operating within classified Hazardous Locations (HazLoc)—environments where flammable gases, vapours, mist, or combustible dust pose catastrophic explosion risks.
For electrical equipment deployed across Spain and the broader European Union, compliance with Directive 2014/34/EU (ATEX 114) is mandatory. Power conversion systems destined for facilities in Tarragona’s Chemical Complex, Puertollano's petrochemical valley, or Cadiz’s naval shipyards must align with rigorous Spanish standardizations managed under UNE-EN 60079 series.
Our engineered HazLoc power supplies incorporate multiple protection concepts designed to eliminate electrical sparks, arcing, and surface hot spots during both normal operations and fault conditions:
| Protection Type | Standard Designation | Engineering Methodology | Operational Benefit in HazLoc |
|---|---|---|---|
| Flameproof Enclosure | Ex d (UNE-EN 60079-1) | Heavy-duty cast aluminum or stainless enclosure built to contain an internal explosion without igniting surrounding gas. | Prevents flame propagation in gas-rich refinery environments (Zone 1 / Zone 2). |
| Increased Safety | Ex ec / Ex e (UNE-EN 60079-7) | De-rated solid-state topology avoiding components that produce arcs or dangerous surface temperatures. | High reliability, fanless conduction cooling with extended operational MTBF. |
| Encapsulation | Ex m (UNE-EN 60079-18) | Hermetic potting of delicate switching circuitry using high-thermal-conductivity resins. | Protects components from moisture, salt-spray oxidation, and explosive dust ingress. |
| Intrinsic Safety Interfaces | Ex i (UNE-EN 60079-11) | Energy-limiting circuitry restricting current and voltage delivered into dangerous zones. | Safe powering of sensors, telemetry units, and low-voltage field actuators. |
In hazardous environments, traditional forced-air fans represent a critical single point of failure. Rotational fan blades can accumulate static charge, collect combustible fine dust, and mechanically seize over time, causing power supplies to overheat rapidly.
Our ruggedized HazLoc power supply designs feature high-efficiency planar magnetics and heavy aluminum baseplate conduction cooling. Heat generated by power MOSFETs and silicon carbide (SiC) diodes is transferred directly via engineered thermal interface materials (TIM) to the outer cabinet heatsink. This enables completely sealed, gasketed enclosures rated up to IP66, IP67, and IP68, guaranteeing long-term continuous operation at ambient temperatures ranging from -40°C to +85°C.

Spain represents a diverse geographic landscape of specialized industries, each demanding distinct electrical and environmental power supply characteristics. As a premier manufacturer and exporter, our power platforms are optimized for Spain's primary industrial corridors:
Spain houses major refinery operations and chemical processing plants managing volatile organic compounds (VOCs), ethylene, and fuel derivatives. In these facilities, control cabinets governing flow meters, automated valve actuators, and toxic gas leak detection systems require uninterrupted DC power.
The Solution: Our ATEX Zone 1 and Zone 2 DIN-Rail and chassis-mount AC/DC converters deliver clean 24V DC power with integrated battery backup (UPS) capabilities, ensuring system safety shutdowns even during severe main grid brownouts.
Under the EU’s decarbonization targets, Spain is installing gigawatt-scale solar PV farms coupled with water electrolyzers for green hydrogen synthesis. Ambient summer temperatures in regions like Seville or Zaragoza routinely exceed 42°C, creating harsh thermal micro-climates inside outdoor power enclosures.
The Solution: Wide-input high-power switching power supplies (1500W–2000W adjustable DC) engineered with wide operating windows and active Power Factor Correction (PFC > 0.98), maintaining 90%+ efficiency without thermal de-rating.
Spain's naval defense manufacturers (e.g., Navantia shipyards) and offshore wind infrastructure installers face continuous exposure to salt spray, heavy mechanical vibration, and wide AC voltage fluctuations aboard vessels and floating platforms.
The Solution: Encapsulated power adapters certified to MIL-STD-810G vibration standards and ISO 12944 C5-M marine anti-corrosion compliance, built to suppress conducted atmospheric interference under stringent CISPR / EN 55032 Class B EMC limits.
Northern Spain’s steel mills, cement plants, and agricultural processing hubs generate high concentrations of airborne metallic and organic dusts, classified under ATEX Dust Zones 21 and 22 (UNE-EN 60079-31).
The Solution: Fully potted Ex tb / Ex tc rated power supply modules providing 300% peak transient current capability to handle inductive motor turn-on surges while sealing out all particulate contamination.
Industrial procurement managers and engineering leads in Spain are currently adjusting to stricter grid compliance frameworks driven by grid modernization and intense industrial automation. The influx of intermittent renewable energy into Spain's national grid (REE - Red Eléctrica de España) has heightened the frequency of temporary voltage sags and line transients.
To prevent severe tool aborts, costly wafer loss in semiconductor fabs, or safety interruptions in continuous chemical plants, critical power supplies must conform to SEMI F47 Voltage Sag Immunity specifications.
Our power conversion architectures integrate energy-storage electrolytic banks and digital feedback control loops that allow the power supply to ride through 50% line voltage dips for up to 1000 milliseconds, guaranteeing unbroken output regulation for critical PLCs, sensors, and telemetry systems across Spanish factories.
With over six decades of heritage in custom power engineering (incorporating proven methodologies from global leaders like Astrodyne TDI), we provide Spanish OEMs with complete design lifecycle protection—from concept feasibility to long-term lifecycle support.
Unlike standard trading companies, we design and wind our transformers, chokes, and inductors in-house. This gives us full control over galvanic isolation boundaries (up to 4000V AC), leakage currents, and thermal dissipation paths.
Every HazLoc power platform is pre-tested in our accredited electromagnetic compatibility laboratories to ensure ample margin under EN 55032 / CISPR 32 for conducted and radiated emissions, reducing your time-to-market in Europe.
Our manufacturing facilities operate under stringent quality management systems. Every single production unit undergoes 100% full-load thermal burn-in and automated functional testing prior to export shipment to Spain.
When standard catalog power supplies fail to meet complex spatial envelope constraints, mounting dimensions, or specialized pinouts, our engineering team collaborates directly with your R&D department.
Clear technical answers to help Spanish buyers, electrical engineers, and logistics specialists streamline procurement and certification verification.
Our explosive atmosphere power supplies are designed and manufactured in accordance with Directive 2014/34/EU and the harmonized UNE-EN 60079 standard series. We provide official CE declarations of conformity along with ATEX / IECEx EU Type Examination Certificates issued by recognized EU Notified Bodies. Products are marked clearly with Ex coding (e.g., CE Ex II 2G Ex db eb IIC T4 Gb / II 2D Ex tb IIIC T135°C Db) to guarantee seamless approval by local Spanish industrial safety inspectors (Inspección Industrial).
Spain operates on a standardized single-phase 230V AC (50Hz) and three-phase 400V AC (50Hz) utility grid.
