Electro-Magnetic Compatibility (EMC)
Electromagnetic compatibility (EMC is the ability of a device or
system to operate satisfactorily in its electromagnetic environment
without causing unacceptable interference or being too sensitive in
practical situations. Xitanium LED Xtreme SR drivers meet EMC
requirements per CISPR15 for conducted and radiated emissions.
This test is conducted with a reference setup that includes a
driver and an LED module + heat sink combination mounted on
a
metal
plate
and
verified
in
Insulation Class I and II
configurations.
Remote mounting and EMC
Xitanium LED Xtreme SR drivers are designed primarily for built-in
use only and not for remote mounting. Remote mounting of
Xitanium LED Xtreme SR drivers may be possible as long as the
additional summarized
voltage
drop
as
function
of output
current along the LED + and LED – wires is accounted for.
Philips has successfully performed CISPR15 EMC compliance tests on
systems with a standard LED output cable length of 60cm as reference.
For longer CISPR15-compliant cable lengths please check the driver
datasheet for the maximum specified length.
If a longer distance beyond the maximum specified distance is required
then the EMC performance needs to be verified separately. The use of
shielded LED output wires is not recommended.
Warning: due to EMC reasons, remote mounting of a SR sensor or
controller is not allowed. The driver, sensor and control wiring must
remain within the same common driver enclosure. Failure to
observe this may result is damage to the driver and EMC non-
compliance!
Note: the length of the two NTC wires between driver and
LED module is not allowed to exceed 60cm; otherwise reliable
operation of the MTP feature is not guaranteed.
Note: the driver EQUI terminal must be connected to the
luminaire chassis as well as to Protective Earth (Class I) for
optimal EMC performance and surge immunity. Doing so for Class
II luminaires is in safety compliance with IEC61347-1, IEC60598-1
and IEC61140 regarding the relation between the driver EQUI
terminal and live parts with respect to:
• Maximum allowable touch current
• Minimum required insulation resistance
• Minimum required creepage distances & clearances
• Minimum required electric strength
The purpose of the driver EQUI terminal is purely functional
and designed for equipotential bonding; it does not have a safety
function.
Electrical insulation
Driver insulation classifications between the several inputs and output
can be found in the driver datasheet. Insulation classifications of
Xitanium LED Xtreme SR drivers are optimized for design-in
in Insulation Class II luminaires by offering double or reinforced
insulation between live and accessible parts. The insulation between
the EQUI terminal and the mains input is classified as double for all
Xitanium LED Xtreme SR drivers.
