Agilent/Keysight E3611A

The Agilent/Keysight E3611A is a 30 W single-output DC bench power supply engineered for laboratory and electronic testing applications requiring stable, low-noise power delivery. It delivers dual-range output with automatic constant-voltage/constant-current (CV/CC) mode selection, enabling precise control whether sourcing from a voltage or current perspective. The instrument combines exceptional load and line regulation with front-panel 10-turn potentiometers for fine adjustment and built-in remote sensing to compensate for lead drop at the device under test.
