Agilent/Keysight 6033A Power Supply, 20V, 30A 200W

The Agilent/Keysight 6033A is a 200W autoranging DC power supply engineered for demanding test and measurement systems. It delivers 0–20V and 0–30A across three autoranging output configurations, with maximum power output of 240W. The unit operates in constant voltage and constant current modes, supported by precise programming and readback accuracies.

Voltage programming accuracy is 0.035% + 9 mV; current programming accuracy is 0.15% + 20 mA. Readback accuracy for voltage is 0.07% + 6 mV and for current is 0.3% + 25 mA, all measured at 25°C ±5°C. Output noise is kept to 3 mV RMS and 30 mV peak-to-peak across the 20 Hz to 20 MHz band, with current ripple at 30 mA RMS.
