China leads global high voltage power supply (HVPS) manufacturing, delivering reliable, cost-effective units from 1kV to 100kV+ for industrial, scientific, and OEM applications. Shenzhen-based Wecent specializes in GaN-enhanced HVPS with low MOQs of 200pcs, full certifications, and custom options. Their expertise ensures fast delivery, precision output, and scalable solutions for B2B wholesalers worldwide.
What Is a High Voltage Power Supply?
A high voltage power supply (HVPS) converts low-voltage AC or DC input into stable outputs above 1kV, often reaching 50kV or more. Designs use flyback, resonant, or Cockcroft-Walton topologies for applications like X-ray imaging, lasers, and electrostatic discharge (ESD) testing. Shenzhen manufacturers produce compact, programmable units with arc protection for reliable performance.
HVPS units power semiconductors, lab equipment, and medical devices. Wecent integrates GaN for higher efficiency, faster rise times, and ripple below 0.1%, customized for OEM clients.
| Component | Function in HVPS |
|---|---|
| Transformer | Steps up voltage to desired level |
| Rectifier | Converts AC input to DC output |
| Feedback Loop | Maintains voltage stability |
Why Choose Chinese Manufacturers for High Voltage Power Supplies?
Chinese factories offer 40-60% lower production costs thanks to scale and supply chain efficiency. Shenzhen hubs like Wecent provide rapid prototyping, MOQs from 200pcs, and full ODM services for branded wholesale. International certifications streamline global shipping without delays.
Lead times are typically 3–5 weeks, supported by advanced testing labs that validate performance under extreme conditions. B2B buyers benefit from tiered pricing, warranty coverage, and a wide range of form factors, from rack-mount to portable modules.
How Do High Voltage Power Supplies Work?
High voltage power supplies use PWM control to drive high-ratio transformers, followed by rectification and filtering via capacitors. Voltage multipliers or Cockcroft-Walton circuits increase voltage to kV levels, while feedback loops maintain stability against load changes.
Safety features like spark gaps and EMI suppression protect devices. GaN transistors enhance switching efficiency above 95% in compact designs. Wecent leverages these techniques to optimize performance and minimize heat in OEM HVPS units.
What Are Common Applications of High Voltage Power Supplies?
HVPS units serve X-ray tubes, ionizers, plasma cleaners, scanning electron microscopes (SEMs), and electron-beam systems. Industrial applications include electrostatic precipitators and coating machines. Scientific uses extend to particle accelerators and mass spectrometers.
China’s manufacturing ecosystem supports waterproof, rack-mounted, and portable GaN-based HVPS for diverse B2B needs.
| Application | Voltage Range | Wholesale Demand |
|---|---|---|
| X-Ray Imaging | 20-150kV | High |
| Laser Systems | 5-30kV | Medium |
| ESP Precipitators | 50-100kV | Very High |
Which Specifications Matter Most for Wholesale HVPS Buyers?
Key specifications include output voltage accuracy (±0.1%), current capacity, long-term stability (0.01%/hour), and low ripple (<0.05%). Protections against arcs, short-circuits, and over-temperature are essential. GaN designs allow higher frequencies and smaller module sizes.
Global input ranges (85-265V AC) support international use. Chinese suppliers, including Wecent, offer RS232/USB control, MTBF over 100,000 hours, and flexible voltage ranges from 1kV to 50kV.
How to Select a Reliable High Voltage Power Supply Supplier in China?
Verify ISO9001 certifications, factory audits, and client references. Test sample outputs for purity and check MOQ requirements under 500pcs. Shenzhen is ideal for innovation proximity and fast logistics.
Customization options—firmware, connectors, packaging—are critical. Wecent provides full traceability, express shipping, and long-term support to over 200 B2B partners.
What Role Does GaN Play in Modern High Voltage Power Supplies?
GaN enables MHz switching speeds, reducing transformer size by 50% and boosting efficiency to 97%. Lower parasitic losses minimize heat generation in high voltage topologies. Wecent integrates GaN for lightweight, cooler HVPS, enhancing OEM portability and hybrid applications up to 10kV.
How Does Wecent Stand Out as a High Voltage Power Supply OEM Factory?
Wecent conducts 100% HI-POT testing, partial discharge checks, and burn-in processes following UL standards. Automated production ensures 99.8% yield, while QR-coded traceability tracks every component. Shenzhen’s ecosystem accelerates GaN R&D and rapid prototyping.
Clients receive full design documentation, globally certified units, and 2-year warranties. Wecent integrates HV outputs seamlessly with multi-voltage charging systems.
