EMC Specifications
During EMC measurements the PKF power module is
measured directly.
The fundamental switching frequency is 510 kHz ±5%
at IO = 0.3…3A
Test Conditions: VI= 53 V, IO= 3A at room temperature
Conducted EMI (input teminals)
External Filter (class B)
Required external input filter in order to meet class B in EN
55022, CISPR 22 and FCC part 15J.
IOstep=
1.5-3-1.5A
PKF 4211A without filter
L1 = 51H ( Recommended part: Siemens B82790-S0513 )
L2 = 10H
