Agilent/Keysight 6652A DC Power Supply

The Agilent/Keysight 6652A is a 500 W single-output DC power supply engineered for automated test environments demanding stable, accurate power delivery with minimal noise. Part of the 665x series, it delivers 0–20 V and 0–25 A (at 40°C) with programming accuracy of 0.06% + 10 mV for voltage and 0.15% + 25 mA for current. The unit combines fast transient response, low ripple (3 mV peak-to-peak), and comprehensive protection circuits to streamline high-throughput test applications.
