Test high-power systems up to 30 kW — such as renewable energy systems, electric vehicle powertrains, data centers, and industrial motor drives — using a single, integrated unit.
Hardware-based control enables immediate adjustments of voltage and current based on external sensors or triggers, supporting a closed-loop testing environment.
Provides up to 1.6 MSa/s sampling for voltage and current, enabling scope-grade waveform capture and analysis directly from the power supply.
Simulate dynamic real-world power conditions by directly outputting complex, time-varying voltage and current profiles from the power supply.
