The HMP4040 is a programmable power supply unit produced by Rohde & Schwarz. It is designed for use in laboratories and various industrial applications where precise and reliable power sources are needed. It comes with a clear and user-friendly display, providing real-time readouts of voltage, current, and power for each channel.

The Rohde & Schwarz HMP4040 (HMP series Hameg) 384W bench power supply has four-channels, an output voltage rating of 32V and a current rating of 10A. These rugged instruments are ideal for a wide variety of requirements from educational and industrial applications. They offer high-efficiency with low residual ripple and many protection functions such as overvoltage protection (OVP), overcurrent protection (OCP), and thermal protection to safeguard both the power supply and connected device.
