Our programmable and high-voltage DC power supplies deliver exceptional output stability (<0.5% drift), ultra-low ripple, and rapid step-response necessary for long-term stress testing.
From sheet-metal processing and copper busbar routing to oscilloscope diagnostic load-testing, Guangdong Fenvix Technology Co., Ltd. controls the complete manufacturing chain inside our Guangdong plant.










Testing and burn-in applications impose extreme operating stresses on power supplies. When aging semiconductor arrays, DC-DC converters, electric drive motors, and traction batteries, the power unit itself must run uninterrupted under full thermal load for days or weeks. Guangdong Fenvix Technology Co., Ltd. builds every power supply with tier-one IGBT switches, heavy copper conductors, and robust cooling geometries designed specifically to survive continuous high-duty-cycle lab environments.
Whether your lab requires high-voltage/low-current systems (up to 3200V DC and above) for capacitor charge-discharge studies or low-voltage/ultra-high-current rectifiers (up to 5000A) for motor winding burn-in, our engineering team configures exact voltage/current quadrants with full CE and ISO 9001 compliance.
