Explore our DOSA-compliant isolated DC-DC bricks, high-efficiency OBC assemblies, and ruggedized power supplies optimized for Serbian telecommunication backbones and e-Mobility deployments.
As South-Eastern Europe undergoes a massive digital transformation, Serbia has positioned itself as the premier telecommunications and data transit hub of the Western Balkans. Key operators including Telekom Srbija (MTS), Yettel Serbia, and A1 Srbija are accelerating nationwide 5G mobile base station deployments, expanding fiber-to-the-home (FTTH) networks, and modernizing edge computing nodes. Concurrently, major regional industrial infrastructure—spanning the Pan-European Transport Corridor X to smart grid expansions by Elektroprivreda Srbije (EPS)—demands unprecedented power supply reliability, compact volumetric density, and thermal endurance.
At the center of this technological leap is the switch-mode isolated DC-DC power module. Operating primarily on standard negative 48V DC bus architectures (-36V to -75V DC input ranges), high-density isolated converters are responsible for stepping down intermediate DC voltages to tightly regulated point-of-load (POL) supply rails (1.0V, 1.8V, 3.3V, 5V, 12V, and 24V) required by modern FPGA, ASIC, RF Power Amplifiers, and processing units in remote radio units (RRUs) and baseband units (BBUs).
Telecommunication infrastructure deployed across the Balkan geography encounters distinct operational challenges. Network nodes situated in topographically diverse regions—ranging from the flat Pannonian Basin in Vojvodina to the rugged Balkan and Dinaric mountain zones—face severe environmental stress, grid voltage fluctuations, and strict space limitations inside weather-sealed cabinets. Traditional open-frame power supplies fail prematurely under such conditions due to thermal degradation, dust accumulation, and insufficient surge withstand voltage.
Our OEM manufacturing facility specializes in engineering DOSA-standard (Distributed-power Open Standards Alliance) board-mounted DC-DC modules. From 1/32nd brick, 1/16th brick, 1/8th brick, quarter-brick, to full-brick form factors, our converters provide complete pin-to-pin functional interchangeability, high galvanic isolation voltage (up to 2250VDC / 3000VAC), zero minimum load operation, and synchronous rectification topology to maximize electrical efficiency.
To serve the specific procurement and engineering needs of Serbian system integrators, design houses, and equipment factories, our high-density DC-DC modules and e-Mobility converters are optimized for four core regional deployment scenarios:
Deployed atop urban rooftops in Belgrade and rural tower sites along the Danube corridor. Our half-brick and quarter-brick modules take 36V–75V input and output high-current 12V/28V/48V rails to drive RF GaN power amplifiers with over 96% peak efficiency, housed in IP67 conduction-cooled enclosures.
Powering high-density server racks and optical transport network (OTN) switches in Kragujevac and Novi Sad data hubs. Non-isolated Point-of-Load (POL) buck regulators deliver fast transient response and sub-1% voltage ripple for ultra-sensitive AI processors and line cards.
Supplying power to onboard rail telemetry, signaling systems, and trackside communication equipment along the Belgrade-Budapest high-speed railway line. Built to withstand extreme vibration and shock, featuring ultra-wide 14V–160V input ranges for train battery compliance.
Integrated into remote telemetry units (RTUs) and supervisory control and data acquisition (SCADA) networks operated by regional power utilities. Encapsulated DC-DC converters ensure continuous 24/7 isolation protection against high-voltage surges and electromagnetic interference (EMI).
Custom 3.3kW to 6.6kW On-Board Chargers (OBC) and 1.8kW auxiliary DC-DC modules integrated into municipal electric transit buses in Belgrade and zero-emission delivery fleets operating across Western Serbia.
High-reliability, fully potted metal-cased power supplies manufactured to withstand extreme mechanical stress, broad thermal shock, and severe ambient noise environments, complying with strict Serbian defense procurement standards.
The telecommunications and industrial power architecture market in Serbia is witnessing three major technological transitions, driven by national decarbonization initiatives and rapid 5G infrastructure maturation:
Legacy telecommunication systems historically utilized direct regulated power conversion, leading to high thermal losses across long board traces. Serbian network architects are rapidly adopting Intermediate Bus Architecture (IBA). In an IBA configuration, a primary isolated DC-DC brick converts the incoming -48V battery bus to an unregulated or semi-regulated 12V or 5V intermediate bus, which then feeds highly efficient, non-isolated Point-of-Load (POL) converters positioned directly adjacent to processors. This approach cuts trace resistive losses by up to 40% and drastically reduces board real estate requirements.
To reduce copper cable weight and line losses in large data centers and tall telecommunication towers, Serbian facilities are transitioning toward 380V HVDC distribution systems. Our range of isolated DC-DC power modules includes high-input series capable of accepting 180V–400V DC and 400V–650V DC inputs, converting high-voltage lines directly down to low-voltage system buses with efficiency ratings over 96%.
Seasonal weather variances across Serbia demand power supplies that operate reliably under broad ambient temperature envelopes without relying on noisy, failure-prone mechanical cooling fans. Our aluminum baseplate-cooled and full-potted encapsulated bricks leverage high-thermal-conductivity materials to transfer heat directly to outer cabinet walls, guaranteeing zero derating up to +85°C baseplate temperature.
