IEC 61000-4-12 Ringing Wave Generator 4KV 16A For EMS Oscillatory
Waves Immunity Test
Standards & Clauses:
IEC 61000-4-12/ GB/T 17626.12 “Electromagnetic compatibility (EMC)–
Testing and measurement techniques –Oscillatory Waves Immunity
test”
ANSI-C62-41 “IEEE Guide for Surge Voltages in Low-Voltage Ac Power
Circuits”
Samples and Restrictions:
Lighting appliances, electronic circuits and equipment
Application:
Ringing Wave Generator Used to simulate non-repetitive damped
oscillatory transient waves in low voltage power lines, control
lines and signal lines in both public and private networks.
Provides an ideal, normative basis for assessing the immunity of
electrical and electronic equipment for domestic, commercial and
industrial use.
Test Principle:
Transients due to power and control switching (or triggered by
lightning strikes), generate ringing wave interference on power
lines, control lines and signal lines. To establish a common
criterion for the evaluation of the immunity performance of
electrical and electronic equipment for domestic, commercial and
industrial use.
Structure:
7-inch touch LCD interface, rich in functions, easy for operation
and upgrading software
Built-in single-phase 10A (16A) power network, 2-in-1, miniaturized
design
EUT output comes with high-strength panel socket, and the test
sample connection is more convenient and reliable
Built-in EUT operating voltage, current monitoring, overvoltage,
overcurrent protections
Intelligent program-controlled high-voltage power supply, with
built-in high voltage overvoltage, overcurrent and short circuit
protections
Ringing wave output intelligent detection, with warnings for
voltage error and no output
Self-diagnosis function, can intelligently judge the abnormal
outputs of high voltage and ringing wave
The main switch adopts the imported switch to ensure stable
waveform, with strong comparability and long life
The waveform will be shown by an external oscilloscope
(oscilloscope should be prepared by user)
