Key Features:
Short-Term Interruptions: Simulate complete interruptions (100%) for both AC and DC applications.
Voltage Dips: Use an external step transformer to simulate voltage dips, with a maximum of 280 V / 16 A for AC and 360 V / 8 A for DC.
Voltage Fluctuations: Implement fluctuations with an automatic ramp function (“bathtub function”), with a maximum of 280 V / 16 A for AC and 360 V / 4 A for DC.
Inrush Current Measurement: Quickly determine inrush currents with settings for phase angle and interruption time. The peak inrush current is displayed and can also be measured with an oscillograph.
Phase Angle Adjustment: Adjustable from 0° to 359° in 1° steps.

Applications:
Short-Term Interruptions: The VIS 1700 can fully interrupt the supply network for a specific period, simulating real-world power outages.
Voltage Dips and Fluctuations: Simulate voltage drops to 40%, 70%, or 80% of nominal voltage and fluctuations in a bathtub curve. The VIS 740 step-down transformer can be used for additional power needs.
Inrush Current Testing: Determine the inrush current by setting the phase angle and interruption time, providing valuable insights into the device’s performance.
