Agilent/Keysight 6433B DC Power Supply

The Agilent/Keysight 6433B is a programmable DC power supply delivering 0–36 V DC at 0–10 A with 360 W maximum output power. Built for both benchtop and automated test system integration, it operates in constant voltage/constant current (CV/CC) mode with continuously variable output adjustable to zero. The unit combines precision regulation—0.5 mV line regulation and 2 mV load regulation on voltage—with low output noise (0.3 mV RMS, 3 mV peak-to-peak) and measurement accuracy of 0.03% + 2 mV for voltage and 0.1% + 2.5 µA for current. Large analog meters provide real-time monitoring of output parameters.
