High-voltage doorhandle capacitors serve as the "heart of stability" for nondestructive testing equipment, providing the precise energy control required for X-ray testing, ultrasonic testing, and eddy current testing applications.
Nondestructive Testing Equipment Requirements
Nondestructive testing equipment demands high-voltage power supplies with:
  • Exceptional stability to prevent test signal fluctuations
  • Minimal ripple and noise for accurate test data
  • Robust shock resistance for frequent load changes
Core Functions
In high-voltage power modules, our doorhandle capacitors provide:
  • Filtering: Smooths high-frequency ripple for clean DC voltage output
  • Energy Storage: Buffers transient load changes to stabilize bus voltage
Key Advantages
  • Superior voltage stability with Class II/III ceramic dielectrics
  • Ultra-low ESR for effective high-frequency ripple filtering
  • Robust mechanical construction with screw terminals
  • Epoxy resin vacuum potting for environmental protection
Our high-voltage doorhandle capacitors provide the reliable foundation needed for precise nondestructive testing diagnostics, ensuring accurate results in demanding industrial environments.
