Product Details
4 lines 3a emi signal filter for fire alarm rf shielding room
Electronic equipment such as computers and other peripherals can
leak sensitive information over conducted and radiated
electromagnetic emanations. These signals transmitted down an
unprotected telephone or a power line can potentially be
intercepted by an enemy or a competitor over the same telephone or
power cable many miles away. Our filters stop the high-frequency EM
signals (or noise) emanating inside the secure environment so they
can’t travel outside the room/ facility overpower or communication
cables.

Electronic devices play a vital role in nearly every industry, from
hospitals, to industrial manufacturing, to the military. Specific
devices rely on uninterrupted and dependable electricity to operate
correctly. However, as more and more electronic devices enter the
market, they create electromagnetic interference that can cause
these devices to malfunction, crash or fail. To protect electronic
devices and systems from damage, EMI Filters block adverse
inferences and allow a steady flow of power. Here, we'll take an
in-depth look at EMI fundamentals, EMI filter applications and the
consequences of EMI across various sectors.
There are two main types of EMI — conducted EMI and radiated EMI. Conducted EMI goes through
conductors, such as wires or power lines, while radiated EMI
travels through the air and does not require a conductor. Both
conducted and radiated EMI can impact the performance of electronic
devices through impairment, degradation, malfunctioning or system
failure.
- We are a professional and famous EMI filter manufacturer.
- Our technical team has more than 10 years’ experience in designing
EMI filter. We know UL VDE CSA CE CQC etc safety standard very
well.
- Our technical service team learn many kinds of test standard such
as industrial application (IEC61800-3 for frequency inverter drive
EN12015 for elevator EN55011 for ISM device etc) and military
application (GJB151A GJB152A etc).We can solve EMI problem quickly
effectively and low-costly.
- Our test equipment: LCR digital bridge/voltage proof
tester/insulation resistance tester/spectrum analyzer/inductor
tester/standard signal source/shield room/interference intensity
tester etc
