Solar Photovoltaic Inverter MPPT Sweeps
Commercial solar string inverters operate at open-circuit voltages up to 1000V. Research and production test beds need to simulate dynamic solar irradiance (cloud shadows, sunrise, and sunset) to test inverter tracking efficiency.
ETM system control software acts as a Solar Array Simulator. By programming voltage and current coordinates, engineers sweep the inverter's MPPT input to verify maximum power extraction efficiency.
SCPI list mode programming, high voltage stability, and high conversion efficiency (>90%).
Dielectric Testing & Material Breakdown
Electrostatic coating labs, material research facilities, and insulation testing stations need precise voltage control without start-up surges or voltage spikes that could pre-maturely damage samples.
The ETM-8001 benchtop unit provides 16-bit D/A resolution, allowing engineers to sweep voltage in millivolt steps. Safety interlocks protect operators if a breakdown occurs.
Ultra-low ripple (≤50mVrms), isolated programming interfaces, and automatic output discharge.
Industrial Robotic Motor & Servo Drive Testing
Heavy industrial servo drives operating on high-voltage DC buses require hundreds of hours of continuous stress testing under high electromagnetic noise environments to verify long-term reliability.
The ETM-8003 (2.4kW) is designed for continuous 24/7 operation. Fully isolated control interfaces prevent high EMI feedback from interfering with monitoring PLCs or industrial control lines.
Galvanic isolation up to 3000VAC, 24/7 continuous duty cycle rating, and Modbus RTU interface support.
Technical Standards & Regulatory Citations
Industrial applications in photovoltaic grid-ties and electric vehicle charging verification require rigorous safety compliance.
