Precision Programmable Power Source (PPPS™): Highly modular bipolar power source that can operate in a verity of modes such as constant voltage (CV), constant current (CC) or constant power (CP) in both AC and DC configurations. The modular design provides the flexibility to mix and match over a dozen different power modules to create an optimum solution to meet specific test requirements as well as a powerful tool for R&D projects. The PPPS includes powerful and easy to use user interface and software that makes generating test sequences, and measurement output parameters fast and easy. A simple and intuitive graphical programming environment allows the user to program and control each module independently. The PPPS features a compact design and provides extensive set of measurement and analysis functions. The PPPS system can also emulate a variety of user-defined power sources, such as batteries, photovoltaic array, DC supply with ramp and step voltage as well as AC power source ranging from fraction of a hertz up to 50KHz with any type of standard or user defined waveforms.
