Agilent/Keysight E3640A

The Agilent/Keysight E3640A is a 30 W single-output programmable DC power supply with dual-range capability, delivering clean, regulated power for test, development, and measurement applications. Its low-noise output—less than 5 mV peak-to-peak and 0.5 mVrms—combined with exceptional load and line regulation ensures repeatable results across demanding workloads. Adjustable overvoltage (OVP), overcurrent (OCP), and over-temperature (OTP) protection safeguard both the supply and device under test. Built-in GPIB and RS-232 interfaces enable straightforward integration into automated test systems.
