Engineered to deliver high precision, ultra-low ripple (<1%), continuous duty under high dynamic loads, and full programmable control via RS485 Modbus and analog telemetry.
Tuzla stands as the maritime heart and industrial manufacturing powerhouse of Istanbul, Turkey. The dynamic ecosystem spanning the Tuzla Shipyard Zone (Tuzla Tersaneler Bölgesi), Tuzla Organized Industrial Zone (TOSB), and Istanbul BMT SAS Industrial Park imposes unique, aggressive demands on high-power test infrastructure.
Dry docks, retrofitting yards, and military shipbuilders along the Tuzla coastal strip require heavy DC power banks to run full-load acceptance trials on auxiliary bow thrusters, diesel-electric pod motors, and high-pressure bilge pumps. High-capacity DC systems simulate generator sets under full brake load conditions.
Automotive tier-1 suppliers and electric commercial chassis builders located within TOSB require wide-voltage DC sources (400V to 800V architectures). These platforms validate inverters, PMAC traction motors, and onboard high-voltage harnesses through high-acceleration torque curves and thermal runaway tests.
Large-scale industrial rewinders and repair service contractors throughout the Marmara corridor depend on high-voltage DC test units to perform insulation resistance profiling, heat-run temperature rise tests, and locked-rotor impedance simulations on large DC winches and crane drive motors before redelivery.
When specifying a high-power DC test source for rotating machinery, standard catalogue power supplies fail primarily due to dynamic reverse electromotive force (Back-EMF), severe inrush currents, and inductive voltage spikes. In testing environments throughout the Tuzla industrial zone, electric motors undergo rapid acceleration, deceleration, locked-rotor tests, and full-load torque rejection. Sizing power infrastructure for these dyno setups requires deep consideration of electrical architecture, thermal dissipation, and safety protocols.
During motor deceleration or emergency trip stages on dynamometer benches, the motor operates as a generator, pumping energy back across the DC link. Standard unidirectional switching supplies experience instantaneous DC-link overvoltage trips or catastrophic output capacitor bank failure under these conditions. Fenvix integrates fast-response electronic active clamping snubber networks and dynamic brake dissipation units (chopper circuits) directly into the DC output stage. This architecture monitors the DC rail voltage at microsecond intervals, diverting regenerated kinetic energy into heavy-duty non-inductive resistor banks, protecting the primary IGBT modules and internal rectifier bridge from surge spikes up to 3,200V.
Induction and brushless synchronous motors draw starting currents between 300% and 700% of nominal full-load ratings during across-the-line start simulations. Specifying a DC power supply strictly based on continuous running power leads to frequent nuisance tripping. Fenvix high-power test sources utilize oversized high-frequency transformers wound with high-conductivity oxygen-free copper busbars and parallel interleaved IGBT stages. This allows a standard 100% continuous duty rating while providing a programmable 150% peak overload reserve for 60 seconds, and 200% surge capacity for 3 seconds, enabling smooth across-the-line starting simulations without requiring test engineers to buy double the steady-state kilowatt rating.
The Tuzla coastline experiences high atmospheric salt concentration combined with ambient summer temperatures that regularly exceed 38°C inside non-air-conditioned industrial fabrication bays. Conventional forced-air power supplies intake corrosive salt spray, leading to tracking, galvanic corrosion of component legs, and premature failure of switchgear. Our heavy-duty motor test platforms (above 48kW) utilize sealed internal air-to-water heat exchangers or direct liquid-cooled cold plates. Sensitive power modules are sealed within an IP54 or IP65 enclosure, while waste heat is efficiently conducted out via closed-loop deionized cooling systems, guaranteeing 24/7 continuous operation without thermal derating.

The industrial corridor bordering Tuzla, Gebze, and Kocaeli is accelerating its transition from mechanical drive systems to fully electric and hybrid power trains.
Driven by IMO 2030/2050 directives and European green port funding, Tuzla shipyards are designing all-electric passenger ferries, hybrid tugboats, and electric harbor support craft. This shift requires marine electrical engineers to deploy megawatt-scale DC test benches capable of certifying DC-bus systems, bidirectional motor drives, and battery energy storage links before vessel installation.
With Turkey’s national vehicle initiatives and multinational commercial transit assembly plants along the Marmara rim, TOSB supplier companies are rapidly moving up the value chain from metal stamping to high-voltage electric drivetrain engineering. Dynamic 800V DC power systems have become vital instruments for automated motor dyno cells and inverter reliability testing.
Factory operators across Tuzla are modernizing variable-speed pump skids, servo-driven extruders, and heavy overhead port cranes. Pre-commissioning DC bus tests and continuous automated burn-in protocols are now standard to eliminate expensive downtime in active maritime loading facilities and high-throughput steel mills.
