• Manufacturer: Power-One

Figure N: Output Ripple Voltage, Il=12.5Amps, Cout=220 µF,
Vin=48 VDC.
Note: Use a 0.1 µf ceramic with a 10 µf tantalum capacitor. Scope
measurement should be made using a BNC socket. Position loads
between 51 mm and 76 mm (2 in. and 3 in.) from the module. The
minimum output capacitance as specified for proper operation
must be present during this measurement.

Electromagnetic Compatibility (EMC)
EMC requirements must be met at the end-product
system level, as no specific standards dedicated to
EMC characteristics of board mounted component

DC-DC converters exist. However, Power-One tests
its converters to several system level standards, the
primary of which is the more stringent EN55022,
Information
disturbance characteristics-limits and methods of
measurement.
With the addition of a simple external filter, the
HBA48T12280 converter will pass the requirements
of Class A conducted emissions per EN55022 and
FCC requirements. The recommended EMI filter is
shown in Figure Q. Please contact Power-One
Applications Engineering for details of this testing.
The results of EMI testing are shown in Figure R and
Figure S.
