The Schloeder VIS 1700 voltage simulator is an indispensable tool for testing and ensuring the electromagnetic compatibility (EMC) and overall reliability of electrical and electronic equipment. By simulating realistic power disturbances, this device helps identify and address potential weaknesses in systems.

With the VIS 1700, various operating modes can be executed. For example, it allows for the simulation of short-term power interruptions from 100% to 0%, where both the duration and the rise and fall times can be adjusted as needed. This capability is crucial for testing devices’ sensitivity to sudden voltage losses.

Additionally, the simulator can create voltage dips by lowering the supply voltage to a predetermined level. These dips can be precisely set at a specific phase angle and duration, which is essential for determining the tolerance of equipment to voltage fluctuations. For such tests, an external step transformer, like the VIS 740, is required.

The VIS 1700 can also simulate internal voltage fluctuations with adjustable slopes, allowing the voltage to be reduced to a preset percentage of the nominal value. This function is critical for evaluating the performance of devices under varying voltage conditions without the need for additional power sources.

Lastly, the inrush current of a test object can be accurately measured at any phase position (0 – 360°) up to a maximum of 16 A nominal current (AC). This is crucial for analyzing the inrush characteristics of devices, a critical factor in the design of electrical systems. The peak inrush current can be displayed on the screen and viewed via an oscilloscope.

The VIS 1700 complies with test standards defined in IEC/EN 61000-4-11 for AC testing and IEC/EN 61000-4-29 for DC testing, making it a versatile and reliable instrument for voltage dip and fluctuation tests.
