Although the Ultimod product series meet these requirements,
the CE mark does not cover this area.
EMISSIONS
Power Factor (Harmonic) Correction
The UltiMod series incorporates active power factor correction
and therefore meets the requirements of EN61000-3-2. Power
factor: 0.98
EN61000-3-3 Flicker & Voltage Fluctuation Limits
UltiMod power supplies meet the requirements of the limits on
voltage fluctuations and flicker in low voltage supply systems.
EN55022 Class B Conducted Emissions
Under appropriate test conditions, the UltiMod series meets the
requirements of EN55022 Class B, without the need for external
filtering.
IMMUNITY
The UltiMod series has been designed to meet, and tested to,
the immunity specifications outlined below:
EN61000-4-2 Electrostatic Discharge Immunity
8kV Air discharge applied to Enclosure
6kV Contact with Enclosure
EN61000-4-3 Radiated Electromagnetic Field
10Volts/metre 80MHz to 2.5GHz applied to Enclosure
EN61000-4-4 Fast Transients-Burst Immunity
+/-2kV
EN61000-4-5 Input Surge Immunity
+/-2kV Common Mode 1.2/50 S (Voltage); 8/20uS (Current)
+/- 1kV Differential Mode 1.2/50 S (Voltage) 8/20 S (Current)
EN61000-4-6 Conducted Immunity
10 V/m 150KHz to 80MHz
EN61000-4-11 Voltage Dips
0% 1s Criteria B
40% 100ms Criteria B
70% 10ms Criteria A
Further details on all tests are available from Excelsys.
Guidelines for Optimum EMC Performance
The UltiMod is designed to comply with European Normative
limits (EN) for conducted and radiated emissions and immunity
when correctly installed in a system. See performance levels
attained above. However, power supply compliance with these
limits is not a guarantee of system compliance. System EMC
performance can be impacted by a number and combination
items. Design consideration such as PCB layout and tracking,
cabling arrangements and orientation of the power supply
amongst others all directly contribute to the EMC performance
of a system.
Cabling arrangements and PCB tracking layouts are the
greatest contributing factors to system EMC performance. It is
important that PCB tracks and power cables are arranged to
minimise current carrying loops that can radiate, and to
