Agilent / HP E3618A DC Power Supply 0- 35V / 0- 1.7A 100% TESTED

The Agilent/HP E3618A is a 30 W single-output DC power supply engineered for laboratory and prototype development. It delivers 0–35 V and 0–1.7 A with dual-range capability, low noise output, and excellent load/line regulation. The instrument operates in constant voltage/constant current mode with automatic crossover, functioning as either a voltage or current source depending on load conditions.

Analog 10-turn potentiometers control voltage and current; simultaneous digital panel meters display both parameters in real time.
