Direct Factory Excellence
Precision Engineering from Raw Metal to Validated Power Cabinets
At Guangdong Fenvix Technology Co., Ltd., we maintain complete in-house manufacturing authority over our industrial DC power supplies, heavy-duty rectifiers, and high-frequency conversion units. Rather than operating as an assembly broker, our 3,000m² facility integrates CNC sheet metal processing, heavy copper busbar fabrication, modular sub-assembly, and full-power load commissioning under one roof.
This closed-loop manufacturing discipline ensures strict mechanical tolerances, superior thermal dissipation, and rigorous electrical insulation across every power module. By controlling each stage, overseas industrial buyers receive certified equipment built with traceably tested components, compliant with ISO 9001 and international safety standards.

Workmanship Workflow
Standardized Power Assembly & Commissioning
Every industrial rectifier and DC power supply passes through a tiered assembly sequence overseen by seasoned electrical technicians to ensure dependable operation in demanding environments.
Stage 01 Assembly Process 1: Chassis & Structural Foundation
Technicians mount high-frequency transformers, heavy choke inductors, and structural isolation barriers onto the reinforced powder-coated base chassis.
Milestone: Mechanical Torque & Structural Inspection
Stage 02 Assembly Process 2: Power Electronics & Busbar Integration
Installation of high-grade IGBT modules, fast-recovery diode arrays, custom copper busbars, and air/water thermal radiators with measured thermal paste application.
Milestone: Thermal Contact & Electrical Clearance Check
Stage 03 Assembly Process 3: Control Harness & Interface Wiring
Integration of DSP/microcontroller driver cards, optical-fiber isolation trigger lines, RS485/Modbus communication modules, and front-panel HMI touch interfaces.
Milestone: Signal Continuity & Dielectric Withstand Verification
Stage 04 Commissioning & Live Load Testing
Engineers connect assembled units to dummy resistance load banks for dynamic voltage adjustment, step-load regulation, thermal imaging, and continuous high-temperature burn-in.
Verification: 0-100% Full-Duty Current & Voltage Sweep
Stage 05 Oscilloscope Precision Waveform Inspection
Using calibrated multi-channel digital storage oscilloscopes, engineers capture output ripple factor, switching transients, rising slopes, and reverse recovery behavior.
Precision: Ripple Coefficient ≤ 1% or Application Target
Stage 06 Final Quality Audit & Export Packaging
Complete documentation review, CE/RoHS compliance verification, terminal torquing, multi-layer moisture barrier wrap, and export-grade reinforced wooden crating.

Quality Assurance
Strict Quality Criteria for Global Industrial Deployments
We apply comprehensive quality governance across electrical safety, mechanical precision, and long-term durability to protect overseas production investments.
100% Pre-Shipment Burn-In
Every power unit undergoes thermal stress burn-in under dynamic full-load cycles to identify infant component failures prior to factory dispatch.
Dielectric & Insulation Test
High-potential (Hi-Pot) insulation resistance testing is performed between input, output, and ground planes to ensure workplace safety under high voltage.
Direct Traceability
Core IGBTs, rectification modules, transformers, and control boards carry individual serial tracking for lifetime maintenance and spare parts support.
Custom Tailoring
Enclosures, cooling loops (water, oil, forced air), and control ports (RS485, Profibus, CAN, Analog 0-10V) are adapted directly to your plant requirements.
