About Fenvix
Custom DC & AC Power Systems Engineered in Guangdong Since 2013
Guangdong Fenvix Technology Co., Ltd. designs and manufactures high-power, high-frequency DC power supplies for surface finishing, electrochemistry, R&D testing and aviation ground support. For more than 13 years our engineers have solved non-standard power problems that catalogue products cannot: 15,000A plating rectifiers, 100kV capacitor chargers, polarity-reversing descaling supplies and 28.5V GPUs for hangars.
Every unit is assembled, burned-in and commissioned in our own workshop, then load-tested against the customer's specification before shipment. Buyers in North America, Eastern and Southern Europe and Southeast Asia rely on us as a direct factory partner, not a trading middleman.

Inside Our Factory
Verified Manufacturing, From Sheet Metal to Load Test
Cabinets, busbars and wiring are produced in-house, so we control mechanical quality, thermal design and lead time instead of relying on outside fabricators.
Your Custom & Special Power PartnerWatch the production process · 2:40 Requirement Review
Engineers confirm load characteristics, input supply, ripple and cooling before quoting a design.
Precision Fabrication
Plate shearing, punching, milling, drilling and tapping of cabinets and copper busbars in our own workshop.
Assembly & Wiring
Power modules, control boards and protection circuits assembled by trained technicians.
Commissioning & Burn-In
Every unit is powered, calibrated and checked with oscilloscopes and loads against the agreed spec.

Buyer FAQ
Questions Overseas Buyers Ask Before Ordering
What information is needed to configure a custom industrial DC power supply?
Send us your input voltage, phase and frequency; rated output voltage and current; control mode (CC, CV or both); acceptable ripple; duty cycle; preferred cooling; control interface such as RS485 or analog 0–10V; installation environment; and any target certification. With these details our engineers size the power stage, cooling and protection correctly the first time.
Is there a minimum order quantity?
No. We accept single-unit orders for prototypes, pilot lines and laboratory projects, as well as batch production for OEM and ODM partners.
When should I choose water cooling instead of forced air cooling?
Water cooling is generally the better choice for very high output currents, continuous 24/7 duty and plating or electrolysis shops where corrosive fumes, dust or high ambient temperature would shorten the life of air-cooled components. Forced air cooling suits most moderate-current and laboratory installations and is simpler to maintain.
Which certifications does Fenvix hold?
We operate an ISO 9001 quality management system. Selected models carry CE, RoHS, LVD and EMC conformity, and our factory has been verified on site by TÜV Rheinland. Test reports for specific models are available on request.
Which trade terms and payment methods do you accept?
Common terms include FOB, CFR, CIF, EXW, FCA, CPT, CIP, DDP and express delivery. Payment by T/T, L/C, credit card, Western Union or MoneyGram, in USD, EUR, GBP, JPY, CAD, AUD, HKD, CHF or CNY.
Do you provide technical support for buyers outside China?
Yes. We provide free pre-sales consultation, wiring diagrams and commissioning guidance, and after-sales support by email and video call. On-site technical support is also available and has been confirmed by an independent third-party assessment.
Have a Non-Standard Power Requirement?
Share your load specs and our engineers will recommend a configuration within one business day.
