The Agilent E3611A is a 30 W single-output DC benchtop power supply engineered for general laboratory applications requiring precise, stable voltage and current delivery. The unit operates in both constant voltage (CV) and constant current (CC) modes with automatic crossover, selecting the appropriate regulation mode based on load conditions. Dual-range outputs—0–20 V at 1.5 A or 0–8 V at 3 A—provide flexible configuration for diverse test scenarios. Front-panel 10-turn potentiometers enable fine adjustment of voltage and current limits. Remote sensing compensates for voltage drops across load leads, ensuring accurate voltage delivery at the device under test. Adjustable overvoltage protection (OVP) and a continuously acting CC circuit protect against overload and short-circuit conditions.
