As Austria solidifies its position as a powerhouse of European mechanical engineering, robotics in Upper Austria, green mobility in Styria, and smart building infrastructure in Vienna, industrial designers face unprecedented spatial and thermal constraints. Keldan delivers TÜV Rheinland onsite-verified switching power solutions designed to exceed ÖVE, EN, and IEC standards.
Select from our field-tested DIN rail modules, ultra-thin enclosed converters, and variable bench power supplies. Each unit provides Class I/II electrical isolation, wide operating temperature ranges (-20°C to +70°C), and high MTBF ratings.
Austrian equipment integrators maintain exceptionally rigorous technical requirements due to the nation's stringent environmental protocols, highly automated manufacturing plants, and high-altitude alpine infrastructure.
In the industrial manufacturing corridors of Linz, Steyr, and Wels, space optimization within IP54 and IP65 control enclosures is essential. Keldan's low-profile 1U enclosed SMPS and slim TS-35 DIN rail units allow machine builders to pack secondary 24VDC logic, PLCs, safety relays, and servo drives into 38mm depth enclosures without requiring external ventilation cuts that compromise IP ratings.
Austria’s Tyrol, Salzburg, and Carinthia regions lead Europe in decentralized hydropower, solar storage, and mountain transit systems (ropeways and rack railways). Operating at elevations exceeding 1,500m necessitates power supplies built with enhanced dielectric clearance distances compliant with EN 50124-1 and EN 60664-1, avoiding high-altitude corona discharge and maintaining continuous operation down to -25°C.
Commercial and institutional facilities throughout Vienna and Graz enforce strict compliance with EN 50491-3 and ÖVE directives for building management. Keldan's ultra-slim HDR and EDR series boast low no-load consumption (<0.3W) aligned with EU EcoDesign Lot 7 regulations, functioning seamlessly in modular secondary distribution boards (Rittal, Eaton, and Hager standard cabinets).
Modern Austrian electrical enclosures are frequently sealed without active refrigeration to prevent ingress of airborne particulates in heavy industrial settings, or damp snow-melt humidity in outdoor junction boxes. Under enclosed ambient conditions, localized internal cabinet temperatures quickly reach 55°C to 65°C. Conventional commercial power supplies exhibit aggressive thermal trip protection or severe output de-rating under these curves.
Keldan addresses this challenge through advanced circuit topologies including synchronous rectification, LLC resonant half-bridge switching, and high-conductivity thermal silicon potting. In our NDR-240 and EDR-120 series, thermal dissipation is routed directly to the extruded aluminum casing, functioning as an integrated conduction heatsink. This design permits 100% full-load output up to 50°C and maintains over 60% rated capacity at 70°C without mechanical fans, entirely eliminating fan bearing mechanical failures.
Austria's electrical grid operates under the high regulatory expectations overseen by E-Control and aligned with EN 50160 grid quality standards. Austrian industrial purchasers require strict adherence to EN 61000-3-2 (Limits for Harmonic Current Emissions), particularly for Class A (three-phase equipment) and Class D (power conversion systems between 75W and 600W). Ordinary switching power supplies draw current in narrow, discontinuous spikes, injecting high Total Harmonic Distortion (THD) back into the line, disturbing sensitive automation equipment.
Our DRP and NDR industrial DIN rail models incorporate active Power Factor Correction (Active PFC) with dedicated boost-converter controller ICs. This architecture continuously tracks the sinusoidal input voltage, shaping the current waveform to achieve a power factor greater than 0.98 at 230VAC 50Hz, with THD suppressed below 10%. As an added safeguard, robust double-sided multi-pole EMI filtering satisfies EN 55032 Class B radiated and conducted limits, permitting placement adjacent to high-gain measurement sensors and PLC communication buses.
