Schlöder’s VIS 1700 Intermittent Voltage Simulator can simulate voltage drops and fluctuations that occur across supply networks (AC and DC). AC tests are defined in IEC/EN 61000-4-11 and DC tests in IEC/EN 61000-4-29.

  • AC Test: IEC / EN 61000-4-11
  • DC Test: IEC / EN 61000-4-29
  • Automatic AC + DC acceleration function (voltage fluctuations, no need for a second voltage source)
  • Measure current at specified phase angle 0° – 360°.


I. Specification of Intermittent Voltage Simulator VIS 1700

Intermittent Voltage Simulator VIS 1700

  • The clearly adjustable VIS 1700 Intermittent Voltage Simulator can simulate voltage drops and oscillations that occur on supply networks (AC and DC). Different modes of operation are possible:
    • 100% Short Term Disruption: The supply network of the tested device may be interrupted for any period for a specified time (0.1 ms – 9980 ms).
    • Threshold voltage: The transition between rated voltage U1 and variable voltage U2 (U2 always <= U1) is always abrupt. The VIS 1700 Schlöder Voltage Breaker Simulator can – regulate – start or end at any phase angle of the mains voltage. Standard inspection is done for 40%, 70% and 80%. This test requires that a voltage U2 of the same phase be applied to the rear of the equipment. Step transformers (VIS 740) have sufficient capacity to meet regulatory requirements. (Figure 1)
    • Voltage oscillation: oscillates to an adjustable voltage (0 – 95% of U1). The parameters of fall time, test time and recovery time (0.1 to 70 seconds each) can be set separately. No additional voltage is required for this (Figure 2)
      Inrush current measurement: Inrush current can be measured at any phase position (0 – 360°) for each test object with a maximum rated current of 16 A (AC).
  • For oscillation tests, there are three BNC sockets on the back of the unit for voltage, current and trigger parameters.
