These 12kV high-power, high-voltage DC power supplies – power range scaling from 8kW to 96kW – address testing requirements ranging from high to ultra-high power levels. Simply put, higher power capabilities allow for handling larger and more complex test loads; applications extend from testing individual components to comprehensive system-level burn-in testing, covering the vast majority of rated-voltage aging test and accelerated aging test needs for medium-to-high voltage electronic components. The primary devices under test are high-voltage components in the 8kV, 10kV, and 12kV voltage classes.
