EMC Specications
During EMC measurements the PKF power module is
measured directly.
The fundamental switching frequency is 510 kHz ±5%
at IO = 0.22-2.2A
Test Conditions: VI= 53 V, IO= 2.2A at room temperature
Conducted EMI (input teminals)
External Filter (class B)
Required external input lter in order to meet class B in EN 55022,
CISPR 22 and FCC part 15J.
PKF 4117 A without lter.
L1 = 884 H
C1, C2 = 680 nF
