B32911*3 ... B32916*3
X1 / 330 V AC
Application note for the different possible X1 / X2 positions
In series with the powerline
(i.e. capacitive power supply)
Typical Applications:
Power meters
ECUs for white goods and household
appliances
Different sensor applications
Severe ambient conditions
In parallel with the powerline
Typical Applications:
Standard X2 are used parallel over the mains for
reducing electromagnetic interferences coming
from the grid. For such purposes they must meet
the applicable EMC directives and standards.
