Engineered to deliver clean, regulated current across fluctuating industrial voltage conditions. Explore our heavy-duty switch-mode units, DIN rail power solutions, and high-capacity bench and variable rectification modules engineered for OEM integration.
Serbia's economy has rapidly transformed into Southeastern Europe's primary manufacturing hub. From the heavy metallurgical plants along the Danube to cutting-edge automotive tier suppliers in Vojvodina and Šumadija, our power supplies deliver dependable continuous current regulation.
Serbia hosts premier global tier-1 automotive manufacturing facilities in Kragujevac, Niš, and Novi Sad. Our EDR-240-24 and HDR series furnish low-noise 24VDC loops powering robotic assembly arms, pick-and-place conveyors, and inline end-of-line electrical testing rigs operating 24/7 without thermal interruption.
The metallurgical basins of Smederevo and the copper-mining districts around Bor require ruggedized constant current sources for electroplating, zinc bath purification, and hard-facing. Our SV-3000 3KW variable units deliver up to 120A continuous regulation under severe high-temperature airborne particulate conditions.
Driven by Serbia's clean energy national transitions, solar utility installations and hybrid commercial microgrids in Central Serbia rely on our SCP-35 mini DC-UPS and PWM charge regulators to guarantee unswerving 12V/24V supervisory telemetry across remote substations during utility brownouts.
Procuring power supplies in Serbia requires strict alignment with national harmonized standards (SRPS), European Union EMC safety directives, and the structural real-world operating realities of the Balkan power grid.
Following Serbian adoption of SRPS EN 61000-3-2, all switched installations drawing over 75W must feature active power factor correction. Our units integrate active PFC stages exceeding 0.95, eliminating reactive penalty charges levied by Elektroprivreda Srbije (EPS) on commercial facilities.
Regional industrial infrastructure frequently experiences line voltage surges ranging between 180VAC and 265VAC during winter peaking. Our products incorporate expanded wide-input stages (85–264VAC) and robust 2KV–4KV surge suppression varistors to prevent downstream microcontroller shutdown.
Pannonian Basin summers commonly push enclosed plant room ambient temperatures past +45°C. Keldan's constant current modules utilize premium 105°C-rated electrolytic capacitors and optimized convection airflow chimneys to minimize thermal de-rating curves.

Unlike trading intermediaries, Yueqing Keldan Technology Co., Ltd. controls the complete manufacturing lifecycle from raw component arrival to automated optical testing at our electrical cluster facility in Zhejiang.
Every reel of MLCC capacitors, power MOSFETs, magnetic cores, and high-frequency ferrite transformers is vetted against stringent ESR and breakdown voltage thresholds.
Automated high-speed surface-mount placement lines and nitrogen-capable reflow ovens eliminate cold-soldering and guarantee high shear strength for vibration resistance.
High-resolution AOI scanners detect solder bridge flaws, component misalignments, or reverse polarities, followed by manual micro-potentiometer tuning for voltage accuracy.
Every completed power supply is locked into heated burn-in chambers under continuous 100% full-load stress to eliminate infant mortality before export packaging.
Comprehensive engineering, regulatory, and shipping answers tailored for Serbian electrical panel assemblers, OEM machine integrators, and procurement directors.
Consult with our senior application engineers to obtain verified CAD dimensional files, comprehensive TÜV laboratory test certificates, custom OEM quotes, or expedited pilot samples tailored for your facility's requirements.
