900 EX Advanced high power test sytem
Powering up to 1MW The 900 EX is ideal for testing and emulating energy storage and drive train components. The increased performance (rise time/slew rate) and increased accuracy make the 900 EX ideal for applications like Heavy Industrial (ships, trains, trucks, and aircraft), Military (hybrid drives and aircraft launch systems), Power Electronics (solar panels, inverters), and Hardware in the loop testing. Digital controls protect critical systems and components, and the system can self-adjust to external environmental events like unstable power sources. The bi-directional system can operate at ± 250kW, or combined, it can scale to ±1MW. The 900 EX, with new LCD touchscreen display, is an intelligent system that will give you the accuracy, speed, and control to add value to your tests.
Features: Industry standard for high performance testing Flexibly test virtually any DC source, load, or battery storage system Enhanced error detection & fault correction Test faster and more efficiently Save time & money Regenerative to the grid Save energy and money More accurately represent real world conditions More predictive results Two channels for flexibility in testing/simulating multiple devices with a single machine Open communication protocol allowing easy integration into any test set-up Self-contained cooling system requiring no external cooling system Control Modes: Voltage, Current, Power, Resistance Voltage with Internal Resistance
