Xantrex XHR 7.5-80

The Xantrex XHR 7.5-80 is a 1000 W programmable DC power supply engineered for benchtop and automated test equipment (ATE) applications. It delivers precisely regulated variable DC output with low noise characteristics and standard overvoltage protection (OVP) and thermal shutdown. Operating from universal AC input (85–250 VAC, 47–63 Hz), the unit incorporates 0.99 minimum power factor correction, enabling full output power from standard 120 VAC, 15 A outlets while reducing input current harmonics and meeting international regulations. Zero voltage soft-switching technology minimizes switching transients, delivering high efficiency, low noise, and reliability. The compact half-rack form factor integrates into test system consoles and OEM equipment while maintaining flexibility through front and rear panel connectors.
