Radiated EMS (Electro-Magnetic Fields )
EMC Specifications
Radiated EMS is measured according to test methods in
IEC Standard publ. 801-3. No deviation outside the VO tolerance
band will occur under the following conditions:
The fundamental switching frequency is 510 kHz ±10 kHz.
Frequency range
0.01...200 MHz
200...1,000 MHz 3 Vrms/m
Voltage level
3 Vrms/m
Conducted EMI (input teminals )
1...12 GHz
10 Vrms/m
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:
Test
Air discharge
Voltage level
±4 kV
Contact discharge ±2 kV
EFT
Electrical Fast Transients on the input terminals could affect the out-
put voltage regulation causing functional errors on the Printed Board
Assembly (PBA). The PKF power module withstand EFT levels of
0.5 kV keeping VO within the tolerance band and
2.0 kV without destruction. Tested according to IEC publ. 801-4.
Output Ripple & Nois e (VOac)
PKF series typical conducted EMI performance
Output ripple is measured as the peak to peak voltage of the funda-
mental switching frequency.
Tes t s et up
The PKF meets class A in VDE 0871/0878, FCC Part 15J, and CISPR 22
(EN 55022), except for the fundamental switching frequency.
Radiated EMI
Radiated emission of electromagnetic fields is measured at 10 m
distance.
30...100 MHz
100...200 MHz
200...230 MHz
60 dB ꢀV/m
40 dB ꢀV/m
30 dB ꢀV/m
230...1,000 MHz 35 dB ꢀV/m
1...10 GHz 46 dB ꢀV/m
Conducted EMS
Electro Magnetic Susceptibility is measured by injection of
electrical disturbances on the input terminals. No deviation
outside the VO tolerance band will occur under the following
conditions:
Frequency range
0.15...300 MHz
Voltage level
1.0 Vrms
The signal is amplitude modulated with 1 kHz/80% and applied in
differential and common mode.
