IEC 61000-4-18 EMC Test 0.5μS±30% Ringing Wave Generator Test
Products Review:
The generator is used to simulate non-repeated damped oscillating
transient waves in low-voltage power lines, control lines and
signal lines of public and non-public networks. To provide an ideal
and normative basis for the evaluation of disturbance immunity of
electrical and electronic equipment for household, commercial and
industrial purposes. Evaluation of ringing wave immunity of
lighting products.
Conforms to the standard: IEC 61000-4-12 and IEC 61000-4-18.
A common criterion for evaluating the immunity performance of
domestic, commercial, and industrial power and electronic equipment
was established for the generation of ringing wave interference on
power lines, control lines, and signal lines due to transients
between power and control switches (or caused by lightning strikes)
Structure and Characteristics:
· 7-inch touch LCD interface, rich in functions, easy to operate,
easy to upgrade software;
· Built-in single-phase 10A (16A) power network, 2 in 1,
miniaturized design;
·EUT output is equipped with high-strength panel socket, which is
more convenient and reliable to connect test products;
· Built-in EUT working voltage and current monitoring, over voltage
and over current protection;
· Intelligent programmable high voltage power supply, built-in high
voltage over voltage, over current, short circuit protection;
· Intelligent detection of ringing wave output, voltage error, no
output warning;
· With self-diagnosis function, intelligently judge the abnormal
output of high voltage and ringing wave;
The main switch adopts imported switch to ensure stable waveform,
strong comparability and long service life
The waveform will be shown by an external oscilloscope (oscilloscope should be prepared by user)
