EMC laboratory and environmental tests
Ahar EMC and the environmental testing laboratory have started working with the aim of modeling industrial environments and real operating conditions of electronic equipment and simulating types of noise according to the IEC61000 standard
What is the Pre-Compliance Test? A test that is used before the main tests and only for the purpose of initial measurement of manufactured products. It is cheap to use these tests and product defects are identified during the design process
including tests:
IEC61000-4-3
Pre-Complaince Test
RF Interference
It is used to evaluate the effectiveness of equipment from the radiation of RF transmitters, such as mobile phones, Bluetooth, radio transmitters, etc
test wave form: AM/KHz
with 80% modulation depth
D: 80 – 1000 MHz: 10V/m
D: 1.4 – 2 GHz: 3V/m
D: 2 – 2.7 GHz: 1V/m
IEC61000-4-4
Pre-Complaince Test
Burst
It is used to evaluate the effectiveness of the equipment from transient pulses caused by the discharge of electric charges and switching elements such as relays on the inputs to the system
test level: 2KV
polarity: negative & positive
voltage peak: 2KV
repeatation rate: 5KHz
coupling type: direct & capacitive
IEC61000-4-8
Pre-Complaince Test
50Hz Magnetic Field
In order to evaluate the effectiveness of the equipment, magnetic fields with the frequency of city electricity, caused by the operation of various motors, lighting, etc., are used
power frequency: 50Hz
continuous operation current: 34,48A
short time operation current: 300A for 3Sec
continuous mode: up to 8hrs
short time mode: 1 to 3Sec
field strength: 30A/m
