PowerMods are capable of providing hazardous energy levels
(>240 VA). quipment manufacturers must provide adequate
protection to service personnel.

EMC Characteristics
EMC Directive 2004/108/EC
Component Power Supplies such as the UltiMod, Xsolo and
Xgen series are not covered by the MC directive. It is not pos-
sible for any power supply manufacturer to guarantee conformi-
ty of the final product to the MC directive, since performance is
critically dependent on the final system configuration. System
compliance with the MC directive is facilitated by xcelsys
products compliance with several of the requirements as out-
lined in the following paragraphs. Although the UltiMod, Xsolo
and Xgen series meet these requirements, the C mark does
not cover this area.
EMISSIO S
Power Factor (Harmonic) Correction
The UltiMod, Xsolo and Xgen series incorporates active power
factor correction and therefore meets the requirements of
N61000-3-2. Power factor: 0.98.
E 61000-3-3 Flicker & Voltage Fluctuation Limits
UltiMod, Xsolo and Xgen power supplies meet the requirements
of the limits on voltage fluctuations and flicker in low voltage sup-
ply systems.
E 55022 Class B Conducted Emissions
For system compliance to N55022, Level B, additional filtering
may be required, for technical support, contact our Applications
ngineering team.

Guidelines for Optimum EMC Performance
All xcelsys products are designed to comply with uropean
Normative limits ( N) for conducted and radiated emissions and
Immunity, when correctly installed in a system. However, power
supply compliance with these limits is not a guarantee of system
compliance and system MC performance can be impacted by
a number of items.
Cabling arrangements and PCB tracking layouts are the great-
est contributing factors to system MC performance. All cables
and PCB tracks should be treated as radiation sources and
antenna. very effort should be made to minimise current carry-
ing loops that can radiate, and to minimise loops that could have
noise currents induced into them.
a. Keep all cable lengths as short as possible.
b. Minimise the area of power carrying loops to minimise radia-
tion, by using twisted pairs of power cables with the maximum
twist possible.
c. Run PCB power tracks back to back.
d. Minimise noise current induced in signal carrying lines, by twisted
pairs for sense cables with the maximum twist possible.
e. Do not combine power and sense cables in the same harness
f. nsure good system grounding. System arth should be a
“starpoint”. Input earth of the equipment should be directed to
the “starpoint” as soon as possible. The power supply earth
should be connected directly t
EMI for XF
The Xsolo series of power supplies have been designed for used
in harsh environments including military applications. For addi-
tional information relating to MIL STD 461F, C 101 and C 102
