IEC 61000-4-11 Single Phase Voltage Dips and Interruptions Generator 

Standards & Clauses:

IEC 61000-4-11/ GB/T 17626.11: Electromagnetic compatibility – Testing and measurement techniques – Voltage dips, short interruptions and voltage variations immunity tests

IEC 61000-4-34/ GB/T 17626.34: Electromagnetic compatibility – Testing and measurement techniques – Voltage dips, short interruptions and voltage variations immunity tests for equipment with mains current more than 16A per phase

Samples and Restrictions:

Luminaries appliances, electronic circuits and equipment

Application:

Voltage dips and interruptions generator is highly reliable and specially designed according to the characteristics and requirements of temporarily down and short interruptions immunity test for single-phase AC voltage. Used to assess the anti-interference ability for voltage transients and short interruptions, of electrical and electronic products connected to low voltage power grids.
Suitable for lighting appliances, electronic circuits and equipment immunity testing.

Test Principle:

Voltage dips and voltage interruption are caused by the failures of power grid and power facilities, or sudden changes in load. The voltage change is caused by a continuous change in the load connected to the grid. If the EUT does not respond to changes in time, it may cause a malfunction. The intelligent voltage dips generator is suitable for voltage dips and short interruption immunity test, simulates the impact on the equipment under test caused by faults in the power grid and power facilities (such as short circuits) or large changes in load. It has the advantages of wide range of dip voltage level and arbitrary setting of dip start phase.

Structure:

1. Adopts 2 regulators, rated voltage is adjustable and automatically self-stable, to avoid the impact of grid fluctuations on test results.

2. 7-inch touch LCD interface, rich in functions, easy for operation and upgrading software

3. The EUT output comes with high-strength panel terminals, making the test connection more convenient and reliable.

4. There are external voltmeter and ammeter on the panel, operator can check the working status of the instrument easily.

Use Environment​:

Power supply: 220V±10%, 50/60Hz

Ambient temperature: 10 °C ~ 35 °C, relative humidity: 30% to 60%, there should be no high concentration of dust, corrosive gas, flammable and explosive objects.
