The Agilent HP 6574A is a 2000 W single-output DC power supply engineered for high-power test, R&D, and production environments demanding precise voltage and current control. It delivers 0–60 V and 0–35 A with exceptional regulation, low noise, and fast transient response. Front panel and analog programming interfaces provide real-time output adjustment, while five nonvolatile storage registers enable quick recall of preset configurations. Integrated protection—overvoltage, overcurrent, and over-temperature—ensures safe operation across dynamic load conditions.
