Custom OEM Switching DC Power Supply Factory & Exporter Serving Dnipro

Heavy Metallurgy & Pipe Fabrication (Interpipe & Rolling Mills)

Industrial rolling mills, induction furnace control systems, and continuous billet processing plants along the Dnipro river corridor produce massive inductive spikes and rapid voltage drops. Standard commercial power supplies suffer premature switching MOSFET degradation under such dirty power conditions.

Our custom OEM switching power supplies integrate multi-stage transient voltage suppression (TVS), Class-B EMI filtering, and over-dimensioned electrolytic storage capacitors to maintain rock-solid 24VDC automation rail feeds without triggering protective dropouts.

Aerospace & Defense Tooling (Yuzhmash & Precision Machining)

Dnipro's precision aerospace heritage demands strict DC voltage regulation tolerances within ±0.5% and low ripple noise below 30mVp-p for computer numerical control (CNC) telemetry, robotic weld heads, and automated inspection jigs.

We provide galvanically isolated buck-boost regulators and programmable DC supplies that prevent ground loop feedback between primary line inputs and sensitive sensor electronics, ensuring micrometric tooling precision even during local generator changeover cycles.

Prydniprovska Railway Hub & Freight Traction Subsystems

As the central transit nexus of Ukraine's rail logistics network, Dnipro's electric traction locomotives, switching yards, and signaling relays operate on wide-swing high-voltage DC buses (typically ranging from 48V to 110V DC) subject to severe mechanical vibration and inductive back-EMF.

Our heavy-duty isolated 48V–96V to 24V/12V step-down converters feature vacuum-impregnated magnetic transformers, silicone elastomer encapsulation, and EN 50155-compliant vibration resilience to guarantee uninterrupted communication and monitoring.

Resilient Microgrids, Battery Banks & Starlink Base Terminals

Current infrastructure conditions throughout central Ukraine necessitate decentralized battery-backed auxiliary supplies (LiFePO4 and lead-acid banks) operating between 12V and 48V. Telecom relays and commercial facilities demand seamless, continuous operation.

Varnix supplies custom 12V/24V to 30V/48V/57V step-up boost converters optimized for powering satellite communication antennas and off-grid communication gateways, maintaining an ultra-high 95% operating efficiency that minimizes battery drain.

Substation Control Gear & Electrostatic Finishing

Surface treatment workshops and electrical substations across Dnipro require high-power constant voltage (CV) and constant current (CC) rectification supplies resistant to airborne acid aerosols and fine particulate conductive dust.

Our industrial-grade electroplating rectifiers and high-frequency switching units incorporate conformal acrylic or polyurethane PCB coatings, sealed tunnel heatsinks, and forced air flow routing isolated from electronic component cavities.

Emergency Medical & Municipal Data Hub Continuity

Hospitals, civic shelters, and emergency telemetry command posts in Dnipro require clean, uncompromised pure sine wave AC backup derived from industrial battery energy storage systems during citywide power allocation rationing.

Our pure sine wave inverters produce clean 220V/230V AC waveform fidelity (<3% THD), ensuring inductive compressor pumps, laboratory analyzers, and sensitive communications hardware operate quietly without harmonic overheating.

Ultra-Wide DC Input Tolerances

Because secondary battery banks undergo deep discharge cycles during scheduled network decoupling, equipment cannot shut off at nominal thresholds. Engineers in Dnipro specify buck-boost converters that sustain a stable 12V or 24V output from inputs swinging from 8V to 40V DC without thermal throttling.

Active Power Factor Correction (>0.98)

Regional energy distribution authorities enforce strict billing penalties for reactive power consumption. Our switching AC-DC power supplies integrate active PFC circuits compliant with EN 61000-3-2, optimizing generator loading and decreasing peak current draws across all manufacturing lines.

Sub-Zero Thermal Resilience (-40°C)

Winter temperatures in the Dnieper lowlands routinely drop to -20°C and below. Unheated warehouses, railway sidings, and outdoor telecom towers require switching electronics designed with cold-rated solid electrolytic capacitors and zero-crossing soft-start topologies to prevent cold-start inrush damage.

European Standard Harmonic Compliance

With Ukraine integrating further into the ENTSO-E electrical grid, exported and retrofitted industrial machinery in Dnipro must adhere strictly to CE, RoHS, and Low Voltage Directive (LVD) protocols, demanding fully certified factory-direct engineering validation.

Rigorous 5-Stage Testing & 100% Full-Load Burn-In

Field failures in remote substations or critical production lines are unacceptable. Every power supply leaving our Guangdong manufacturing plant undergoes automated component checking, surface-mount inspection, automated function testing, 4 to 12 hours of full-load thermal burn-in under elevated ambient temperatures, and final oscilloscope wave validation.

Full Customization: Voltage, Housing & Private Labeling

We provide design-based and sample-based OEM modifications tailored to Ukrainian machinery manufacturers: custom multi-tap secondary windings, specialized DC connectors (such as Deutsch or Anderson plugs), proprietary voltage presets (e.g., 13.8V, 27.6V, 57V), customer-branded silk-screened extruded housings, and custom retail packaging.

Reliable Logistics Corridors to Dnipro via Poland & Romania

Navigating modern logistics to Eastern Ukraine requires established freight routes. Varnix maintains routine consolidated container and multimodal road-freight logistics routed through maritime hubs in Constanța (Romania) and Gdańsk (Poland), transitioning smoothly via custom bonded overland trucking directly into customs warehouses in Dnipro.
