The EEC 8500 Series is the most power-dense and functionality-rich power source in our history, giving you improved capability, functionality, and a reduced footprint all in one series. This series is manufactured for simulating common grid faults, voltage dips, and other power abnormalities. The 8500 Series provides an output voltage of up to 310 VAC and an output frequency ranging from 5 Hz - 1,200 Hz making it the obvious solution for all kinds of applications. Not to mention, an enhanced interface to all models is completely designed with the end-user in mind. Our 8500 Sources can be configured as a simple AC Power Source in Standard mode or, as an upgraded option, in Programmable mode. The programmable mode adds the benefits of a sweep of voltage, frequencies, transients, and DC bias over the course of a single sequence or several different tests. The 8500 Series includes the following models: 8505, 8512, 8520, 8530, 8540, & 8560.
