As Novi Sad solidifies its position as Serbia’s leading research, automotive development, and electrical manufacturing corridor—anchored by the Science and Technology Park Novi Sad (NTP), the University of Novi Sad Faculty of Technical Sciences (FTN), and rapid expansions across the Sever 4 and Radna Zona Sever economic estates—the demand for precision-grade, CE-compliant burn-in and lifetime endurance testing systems has escalated. Guangdong Fenvix Technology Co., Ltd. delivers high-frequency, IGBT-based adjustable switching DC power supplies engineered specifically to meet the continuous duty requirements (24/7/365) of European Tier-1 automotive electronics suppliers, power semiconductor fabricators, and telecommunication hardware assemblies.
All export configurations delivered into the Novi Sad and wider South Bačka district undergo rigorous pre-shipment validation under our ISO 9001 certified and TÜV Rheinland on-site inspected facility. Units feature full conformity with EU Low Voltage Directive (LVD 2014/35/EU), Electromagnetic Compatibility (EMC 2014/30/EU), and RoHS 2011/65/EU directives, guaranteeing low harmonic feedback into local utility feeds (EPS distribution network) and seamless integration into SCADA, Profinet, and Modbus-automated production lines.
Factory-calibrated power supplies configured for component stress screening, high-voltage aging benches, electrochemical plating, and continuous testing lines.
Analyzing the exact production criteria in Sever 4, Kać, Rimski Šančevi, and Bačka Palanka manufacturing clusters.
Novi Sad houses prominent automotive engineering operations specializing in motor controllers, onboard chargers (OBC), and wiring harnesses. During elevated temperature burn-in testing (HTOL - High Temperature Operating Life), power supplies must deliver ultra-stable current under fluctuating thermal ambient conditions up to 55°C without thermal derating or premature safety tripping.
With research initiatives at FTN Novi Sad driving power electronics innovation, test benches require fast rise-time programmable DC sources. When evaluating SiC and GaN MOSFET switches, our 800V–2000V DC switching modules allow programmable step slopes, voltage ramp cycling, and millisecond-level overcurrent clamping to avoid damaging prototype wafer lots during avalanche stress runs.
Vojvodina’s heavy machinery and agricultural equipment fabricators depend on high-durability surface coatings. Fenvix water-cooled rectifiers operate inside fully sealed NEMA 4X / IP54 equivalent steel enclosures, entirely isolating internal IGBT modules and copper planar buses from ambient acidic vapors, hydrochloric mist, and airborne conductive dust common to electroplating plants.
Navigating the transition toward high-efficiency power electronics, energy optimization, and Industry 4.0 integration.
The manufacturing ecosystem in Novi Sad is undergoing a profound structural upgrade. Historically centered around agro-processing and light mechanical assembly, the capital of Vojvodina has transformed into an epicenter of foreign direct investment (FDI) from Germany, Japan, Switzerland, and Austria. This industrial re-orientation has generated three critical shifts impacting test engineering and power equipment procurement:
Older workshops across Novi Sad’s older industrial corridors frequently operate legacy silicon-controlled rectifier (SCR) sets. While rugged, these units exhibit poor efficiency (often below 72%), high displacement factor, and substantial ripple (exceeding 5% without bulky LC filter banks). Modern quality standards—such as ISO/TS 16949 for automotive validation—strictly prohibit excessive output ripple because it distorts component thermal curves during accelerated lifetime screening. Fenvix switch-mode rectifiers operate at 20kHz–50kHz switching rates, achieving efficiency figures above 90% while slashing physical cabinet footprint by up to 65%.
With electricity tariffs rising across Southeast Europe and stricter EPS enforcement of grid harmonic limits (standard EN 61000-3-12), plant engineers cannot afford poor power factor equipment that incurs grid penalty tariffs. Fenvix programmable systems are engineered with active power factor correction (PFC ≥ 0.98) and low harmonic distortion topologies (THD < 5%), safeguarding facility power distribution from voltage sags, neutral line overheating, and inductive interference on neighboring automated PLCs.
Manual knob adjustments are being eliminated in favor of digitized, unattended burn-in testing chambers. Factories along the Novi Sad-Subotica industrial artery require power sources that integrate immediately into LabVIEW environments, Siemens Step 7 architectures, and custom Python data loggers. Standardizing on RS485 (Modbus RTU), isolated 0–5V/0–10V analog signals, and Ethernet-ready protocols allows plant supervisors to log voltage, current, and chamber status directly into enterprise MES databases.
| Performance Parameter | Legacy SCR / Thyristor Rectifier | Fenvix High-Frequency IGBT Supply | Impact on Novi Sad Testing Plants |
|---|---|---|---|
| Operating Efficiency | 70% – 76% | 90% – 93% | Lowers thermal room load; saves 18–22% kWh per test bank |
| Output Ripple Factor | ≥ 5% RMS (standard) | ≤ 1% – 0.2% RMS | Guarantees true component thermal stress; eliminates fake failures |
| Enclosure Protection | Open Louver / IP20 Air | Sealed IP54 / Water-Cooled | Survives corrosive industrial atmospheres without PCB corrosion |
| Dynamic Slew Rate | Slow (> 150ms response) | Fast (< 5ms step response) | Essential for rapid automotive load-dump and cyclic testing |
| CE Compliance Rigor | Self-declared baseline | CE / LVD / EMC + TÜV Audited | Simplifies EU safety audits and workplace safety (ZNR) protocols |
Step-by-step engineering calculation to avoid undersizing power stages or overpaying for cooling overhead.
Burn-in testing operates at uninterrupted full load for 24 to 240 hours. Sizing calculations must not plan operation at 100% rated capacity. Always apply a 20% continuous duty derating margin:
This buffer guarantees long IGBT life and prevents thermal tripping in non-air-conditioned factory zones in summer.
Evaluate your facility infrastructure before specifying air or water cooling:
Fenvix supplies matched stainless-steel heat exchangers with inlet/outlet temperature interlocking.
Prevent ground loops and control signal interference in multi-channel rack arrays:
Fenvix control boards feature standard 1.5kV optical isolation across all logic and measurement outputs.
Guangdong Fenvix maintains 100% internal control over sheet metal machining, copper milling, electronic assembly, and pre-export load testing.
Unlike commercial exporters who rebrand generic chassis, Fenvix controls every tier of production in our 3,000 m² factory in Guangdong. Our CNC shearing, punching, and milling machines fabricate custom heavy-gauge enclosures tailored to your facility dimensions. Heavy electrolytic copper busbars are silver- or nickel-plated in-house to minimize junction contact resistance and avoid hotspots during multi-day high-current burn-in runs.
Over a decade of solving non-standard industrial challenges where catalogue power supplies fall short.
Whether you require a low-voltage high-current 12V/6000A setup, an ultra-compact 19” sub-rack chassis, or a massive 100kV capacitor charging installation, our team configures power stages directly to your physical spatial constraints and thermal cooling infrastructure without high engineering redesign surcharges.
