We Design. We Build. We Deliver.
Engineered for low thermal losses, extreme electromagnetic compatibility, and zero-power latching mechanisms across Spain's commercial and industrial electronic landscapes.
Understanding the engineering transition from traditional monostable relays to magnetic bistable latching architectures in European energy systems.
Unlike continuous-duty electromagnetic relays, latching relays utilize permanent magnets to hold contacts in either ON or OFF state. Power is consumed strictly during a 50ms-100ms pulse trigger, slashing overall cabinet thermal dissipation by up to 98%.
Built with heavy silver alloy contacts (AgSnO2) and optimized spring tension mechanisms, our components resist contact welding during intense surge events, fully complying with IEC 62052-31 UC2/UC3 short-circuit requirements.
Hermetic and epoxy-sealed encapsulation options safeguard internal contacts against industrial humidity, airborne salt spray along Spanish coastal regions, and extreme heat conditions common in Southern European summer deployment.
Spain is currently positioned at the absolute forefront of Europe’s transition toward decarbonized electrical infrastructure, smart metering modernization, and widespread electric vehicle adoption. Driven by national climate targets under the Plan Nacional Integrado de Energía y Clima (PNIEC 2021-2030), Spanish Distribution System Operators (DSOs) such as Iberdrola (i-DE), Endesa Distribución, and Naturgy (UFD) have established stringent performance and durability parameters for electrical switching components installed across the Iberian peninsula.
Latching relays operate via a magnetic bistable circuit. When an electrical pulse of correct polarity is applied to the coil, it generates an electromagnetic force that overcomes the internal spring mechanism, pulling the armature into contact with a permanent magnet. The permanent magnet maintains the contact closure mechanically even after the pulse subsides.
When engineering systems for the Spanish market, OEMs must evaluate two primary coil configuration options:
Exporting electrical equipment to Spain requires adherence to rigorous European Harmonized Standards (EN) and Spanish National Standards (UNE). Key regulatory touchpoints for latching relay integration include:
Tailored power switching deployments supporting Spain's key industrial, agricultural, and urban modernization corridors.
Southern Spain leads Europe in solar irradiance and massive utility photovoltaic plant installations. Our high-voltage DC latching contactors (up to 1,500VDC) serve as essential DC bus isolation switches.
Spain's smart grid infrastructure relies heavily on PRIME protocol powerline communication meters. Heavy-duty PCB latching relays (90A–100A) manage automated remote connect/disconnect cycles.
Manufacturing and automotive assembly plants in Northern Spain require low-noise, vibration-resistant switching for machine tools, conveyor lines, and heavy motor controls.
Under the Spanish PERTE VEC program, ultra-fast charging corridors are rapidly expanding. 200A to 500A latching contactors manage high-power battery buffer switching and vehicle isolation.
Altran Magnetics, LLC designs, builds, and delivers premium electromechanical components engineered to solve complex power switching, electromagnetic interference (EMI), and air-flow management challenges for international OEMs.
Operating under strict ISO-certified management systems, our engineering team works directly with Spanish procurement teams and design engineers—reviewing load profiles, short-circuit duty cycles, thermal dissipations, and physical enclosure constraints prior to issuing part numbers.
Every single latching relay batch undergoes 100% functional testing, dielectric withstand verification, and automated contact resistance logging to guarantee fault-free deployment in European markets.
Direct technical answers addressing common procurement, engineering specification, and regulatory compliance queries.
For reliable contact state transition without overheating the internal coil wire, a square voltage pulse of 50ms to 100ms is recommended. Driving the coil with a pulse shorter than 30ms may cause incomplete mechanical latching, while continuous energization exceeding 1 second defeats the energy-saving design and can damage the coil winding.
Yes. All exported latching relays and DC contactors hold comprehensive certification packages including CE marking, TUV, CQC, and UL compliance aligned with UNE-EN 61810-1 and IEC 62052-31. Full declarations of conformity, material composition reports (RoHS & REACH), and test reports are supplied alongside sample qualification packages.
High-voltage DC arcing is inherently destructive because DC voltage lacks a natural zero-crossing point. Our heavy-duty contactors (such as the 200A and 500A models) utilize hermetically sealed ceramic chambers injected with high-thermal-conductivity inert gas (such as Hydrogen/Nitrogen mix) combined with magnetic blowout arrangements that stretch and extinguish DC arcs within milliseconds.
Absolutely. Custom mechanical engineering is a core strength. We design custom copper busbars, bent PCB pin configurations, custom coil wiring harnesses, and custom housing mounting flanges according to your CAD drawings under strict revision control to streamline your factory assembly process.
Because latching relays consume zero holding power in steady state, their internal temperature rise is significantly lower than monostable relays carrying equivalent continuous load currents. However, for ambient operating environments above +70°C inside sealed junction boxes, we recommend selecting Silver Tin Oxide (AgSnO2) contacts with Class F (155°C) coil insulation systems, which are standard across our heavy-duty product families.
Standard engineering samples ship within 3 to 5 business days via express courier. Production quantities typically feature flexible MOQs starting at 500 units for standard catalog models, with sea freight delivery to major Spanish ports within 3 to 4 weeks or express air freight delivery within 5 to 7 days.
