Engineered by Yueqing Keldan Technology Co., Ltd. for harsh electrical noise environments, high-density control cabinets, and mission-critical 24/7 automation systems across the Osrednjeslovenska industrial basin.
A comprehensive engineering breakdown of why high-efficiency TS-35 DIN rail power supplies represent the foundational heartbeat for Slovenian automation engineering, clean technology, and export-oriented robotics.
Ljubljana sits at the convergence of Europe's Priority Transport Corridors V (Venice-Trieste-Koper-Ljubljana-Budapest) and X (Salzburg-Ljubljana-Zagreb). This positions the region as the premier logistics and advanced distribution nexus for Central and Southeastern Europe. Modern high-density distribution centers in Logatec, Vrhnika, and Komenda depend continuously on 24V DC automated sorters, pick-and-place gantry robots, and PLC-governed automated guided vehicle (AGV) dispatch points where power disruption equals instant supply chain choke points.
With corporate pharmaceutical giants like Lek (a Sandoz company) and Krka deeply entrenched throughout Central Slovenia, cabinet hardware must comply with the world's most rigorous Good Automated Manufacturing Practice (GAMP 5) criteria. Power supplies operating in sterile batch manufacturing, clean steam delivery, and isolator air monitoring cannot radiate electromagnetic noise that distorts micro-volt sensor loops, requiring EN 61000-6-3 radiated emission compliance and certified Class B conductive suppression.
The Slovenian automotive supply cluster—supplying precision structural components and mechatronics to major German, Austrian, and Italian vehicle assemblers—utilizes robotized welding, laser ablation, and high-frequency CNC milling. The associated control panels inside localized production plants (such as Hella Saturnus Slovenija) face acute internal heat build-up. Our slimline NDR and MDR series guarantee full rated output up to 50°C and operate reliably in temperatures exceeding 70°C with nominal derating, reducing cabinet air conditioning costs.
Bridging industrial field hardware with dependable power conversion topology across critical infrastructure and manufacturing installations.
Modern distribution complexes surrounding BTC City and regional cargo yards demand 240W to 480W active PFC rail supplies (NDR-240) to drive 24V motorized roller conveyors, bar-code reading tunnels, and pneumatic diverters. Low ripple and high inrush capacity prevent nuisance tripping when inductive DC brake coils actuate.
Pharmaceutical cleanrooms in Menges and Ljubljana rely on ultra-slim MDR-20 and HDR-30 modules powering SCADA telemetry, peristaltic dosing pumps, and mass-flow meters. Double insulation (Class II) eliminates earth leakage current loops, preserving the integrity of sub-millivolt pH and dissolved oxygen probes.
Ljubljana’s burgeoning photonics and laser research institutes utilize our SV-3000 and 1000W adjustable variable power supplies. Precision dial controls and external analog programming enable seamless integration into customized laser diode driver racks and pulse electroplating test benches requiring absolute current stabilization.
Energetika Ljubljana's urban district heating network relies on distributed substation remote terminal units (RTUs). Our DIN rail switching supplies feature broad AC input windows (90-264VAC) and robust voltage dip withstand capabilities to maintain uninterrupted telemetry even during regional grid switching transients.

Adapting your automation hardware to the evolving green, digital, and regulatory framework of the European Single Market.
Under the European Ecodesign Directive and EN 61000-3-2 standards, harmonic current suppression is compulsory across all industrial loads exceeding 75W. Slovenian factory auditors in Ljubljana and Maribor scrutinize power factor performance. Keldan's active PFC topologies maintain a Power Factor >0.98 at rated load, preventing costly reactive energy surcharges on industrial electricity meters.
Floor space inside modern factory floors costs upwards of €1,400 per square meter across central industrial parks. Panel builders are actively migrating to slimline chassis. By utilizing low-loss silicon switches and planar magnetics, our NDR and HDR units achieve an average 32% width reduction compared to legacy frame power supplies, allowing an extra 3 to 4 auxiliary safety contactors per rail section.
Continuous process lines in chemical synthesis and automated compounding cannot tolerate even 15ms voltage drops during grid disturbances. Keldan's rail ecosystem supports parallel operation with decoupling OR-ing diode modules and seamlessly pairs with our pure sine wave inverters and external battery backups to provide clean, uninterruptible 24V control power.
A manufacturing framework verified by TÜV Rheinland on-site in Yueqing, China—combining component traceability, engineering customization, and proven export logistics to the Port of Koper and Ljubljana Jože Pučnik Airport.
Backed by over 44 verified on-site staff and 5+ senior power electronics engineers, each possessing over 5 years of specialized SMPS circuit design experience. We review client schematics, optimize thermal heatsink layout, and provide custom terminal block configurations on demand.
Zero component infant-mortality leaves our factory floor. Every DIN rail module undergoes 4 to 8 hours of continuous thermal full-load burn-in at elevated ambient temperatures within specialized testing chambers, paired with automated SMT placement, AOI optical inspection, and final dielectric hi-pot safety testing.
