BXA15 and BXA30 SERIES
Design Note 100 Rev. 01 - Feb. 1999
• Safety and the low voltage directive
• Electromagnetic Compatibility Immunity
• Electromagnetic Compatibility Conducted and
Radiated Interference
• Telecom and Distributed Power Architecture Features
• System Protection Features
• Thermal Considerations
• Input Impedance Considerations
1. Safety and the Low Voltage Directive
The BXA15 and BXA30 series is intended to be supplied only from a
SELV (Safe Extra Low Voltage) circuit or a TNV (Telecommunications
Network Voltage) power source which are insulated from the AC
mains by reinforced insulation. Basic isolation, tested to 1,500VDC,
for EN60950 and UL1950, is provided.

DC Distributed Power of 12V, 24V or 48V
Central Office -48V
2. Electromagnetic Compatibility Immunity
Good design practice dictates that the electronic system be immune
to noise interference. This practice has now been encapsulated in
European law in the form of the EMC directive. It is imperative that
any system on sale in the European Union meets the terms of the
EMC directive and thus carries the CE mark. To simplify system
compliance to the EMC Directive, the BXA15 and BXA30 have been
designed to meet and comply with the necessary immunity stan-
dards.

3. Electromagnetic Compatibility Conducted and
Radiated Interference
Radiated Interference:
The BXA15 and BXA30 series meet the harmonised standard
EN55022 level A and CISPR22 level A. The series almost meets the
requirements of level B. System performance to level B could be
assured with the appropriate enclosure.
Conducted Interference - Level A Internal Filter Option:
All three input voltage versions of the series, 12VDC, 24VDC and
48VDC, are available with an internal filter option which meets input
conducted noise per VDE0871/8-A or EN55022-A. To order a model
with the internal filter, add ‘-F’ after the model number eg. BXA15-
48S12-F.
Conducted Interference - Level B External Filter:
The addition of an external capacitor enables the BXA15 and
BXA30 products to meet VDE0871/8-B, EN55022-B and CISPR22-B
conducted noise limits. The test set-up is per VDE 0877 Part 1 fig.4
with the load < 10 cm's away from the test converter.

capacitors in close parallel.
For height critical applications, the ITW Paktron capacitor offers a
low profile of <7mm.
Note on the test set up and system grounding:
The products meet input conducted noise VDE0878-B, EN55022-B
and CISPR22-B 10kHz - 30MHz, if the load is not more than 10
cm's away. Tightly parallel tracks or twisted pair wiring to the load
should be used. Long leads to the load could radiate common
mode noise, typically above 20 MHz, back to the input power leads.
Conducted emissions should be checked at a system level.
If the unit fails level B at a frequency greater then 20MHz, because
of system wiring, an additional external ‘Y-capacitor’ could be con-
nected between input ground and output common, to locally
decouple common-mode noise. This capacitor type is usually
intended for use in interference suppression between line and earth.
A recommended capacitor is EVOX-RIFA PME271Y422M or equiva-
lent.
4. Telecom and Distributed Power Architecture
Features
Input Undervoltage Protection:
Internally, the BXA15 and BXA30 series contain an undervoltage
lockout zener circuit. The converter should not be operated continu-
ously at levels between the ‘maximum guaranteed-off-threshold’
and the ‘minimum guaranteed-on-threshold.’
