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.
