EMC Specifications
The PKF power module is mounted on a double sided printed circuit
board (PB) with groundplane during EMC measurements. The
fundamental switching frequency is 485 kHz ±15% @ I
O
=
(0.5...1.0) × I

Radiated emission of electromagnetic fields is measured at 10 m
distance.

The signal is amplitude modulated with 1 kHz/80% and applied
both differential and common mode.
Radiated EMS (Electro-Magnetic Fields)
Radiated EMS is measured according to test methods in IEC
Standard publ. 801-3. No deviation outside the V

ESD
Electro Static Discharge is tested according to IEC publ. 801-2. No
destruction will occur if the following voltage levels are applied to
any of the terminal pins:

Air discharge
±4 kV
Contact discharge
±2 kV
EFT
Electrical Fast Transients on the input terminals could affect the
output voltage regulation causing functional errors on the Printed
Board Assembly (PBA). The PKF power module withstand EFT
levels of 0.5 kV keeping V
O
within the tolerance band and 2.0 kV
without destruction. Tested according to IEC publ. 801-4.
Output Ripple & Noise (V
O
ac)
Output ripple is measured as the peak to peak voltage of the funda-
mental switching frequency.
The operating frequency vs. load and input voltage (72V, 48V and 38V).
Tp= +25 C.

Conducted EMS
Electro Magnetic Susceptibility is measured by injection of elec-
trical disturbances on the input terminals. No deviation outside
the V

tolerance band will occur under the following conditions:
PKF series typical conducted EMI performance
Test set up
The PKF meets class A in VDE 0871/0878, FCC Part 15J, and CISPR 22
(EN 55022).
