Electromagnetic compatibility (EMC)
The electromagnetic compatibility (EMC) of an electrical device is its capability of functioning
as intended in an electromagnetic environment without emitting electromagnetic interference
that could impair the operation of other electrical devices in the vicinity.
Electromagnetic compatibility - immunity
EN 61000-4-2
Electrostatic discharge
8 kV air discharge to all surfaces
4 kV contact discharge to exposed conductive surfaces
EN 61000-4-3
Radiated electromagnetic field
80 ... 1 000 MHz, 10 V/m, 80 % AM at 1 kHz
1.4 ... 2.0 GHz, 3 V/m, 80 % AM at 1 kHz
2.0 ... 2.7 GHz, 1 V/m, 80 % AM at 1 kHz
EN 61000-4-4
Fast transient bursts
2 kV, 5 kHz with coupling network to AC and DC system power
1 kV, 5 kHz with coupling clamp to inputs/outputs
EN 61000-4-5
Surge immunity
DC systems - 2 kV common mode, 1 kV push-pull
For DC systems (I/O signals, DC power supplies), external protection is
necessary.
