EN 50147 Electromagnetic Shielded Room High-performance Shielding Effectiveness EMC Test Equipment
Standards & Clauses:
EN50147 “High-performance shielding room shielding effectiveness of
the measurement method”
CISPR17 “passive radio interference filter and suppression element
suppression characteristics of the measurement method”
CISPR25 “Radio disturbance characteristics of vehicles, boats and
internal combustion engines Limits and methods of measurement for
the protection of vehicular receivers”
ISO11452-4 “Road vehicles with narrowband emitted electromagnetic
energy electronic interference components test method BCI large
current injection method”
GB/T 50719-2011 “Electromagnetic shielding room engineering
specifications”
GB/T 12190 “Electromagnetic shielding room shielding effectiveness
of the measurement method”
Samples and Restrictions:
The electromagnetic shielding room is used to isolate the electromagnetic environment indoors and outdoors to ensure the normal operation of indoor electronic and electrical equipment. Mainly used for conducted emission test, conducted immunity test, EMI discontinuous interference test, etc.
Application:
Electrical appliances and electronic devices, including in-car
electronic systems, generate a certain amount of electromagnetic
waves at work that may interfere with surrounding equipment or be
received by specialized equipment.
The electromagnetic shielding room is used to isolate the
electromagnetic environment indoors and outdoors, which can prevent
external electromagnetic interference from entering the room to
affect the test, and can limit the electromagnetic leakage of
indoor high-power high-frequency equipment to prevent the influence
to people and equipment around. It is the ideal venue for EMC
testing.
Test Principle:
Electromagnetic shielding room is mainly used for automotive electronic conduction emission (CE) test, transient conducted immunity test, bulk current injection method (BCI) test, stripline method test, etc.
Structure:
Power supply: 380V ± 10% 50 / 60Hz
Ambient temperature: 5 °C ~ +40 °C, there should be no high
concentration of dust, corrosive gas, flammable and explosive
objects
Typical Application:
| Typical Application | Conducted Emission Test (CE) |
