LC45iC-DA-100-900 LED driver is suited for built-in usage in luminaires. With LC1x70-SR/LC-SRB/LC-SRB-LOOP strain relief, independent
use is possible too. In order to have safe and reliable LED driver operation, the LED luminaires will need to comply with the relevant
standards and regulations (e.g. IEC/EN 60598-1). The LED luminaire shall be designed to adequately protect the LED driver from dust,
moisture and pollution. The luminaire manufacturer is responsible for the correct choice and installation of the LED drivers according to
the application and product datasheets. Operating conditions of the LED drivers may never exceed the specifications as per the product
datasheet.
Installation & operation
Maximum ambient and t
c
temperature
:
• For built-in components inside luminaires,
the
t
a
ambient
temperature range is a guideline given for the optimum
operating environment. However, integrator must always
ensure proper thermal management (i.e. mounting base of the
driver, air flow etc.) so that the
t
c
point temperature does not
exceed the
t
c
maximum limit in any circumstance.
• Reliable operation and lifetime is only guaranteed if the
maximum t
c
point temperature is not exceeded under the
conditions of use.
LED driver earthing
• LC45iC-DA-100-900
is Class I LED driver suitable for Class I and
II luminaires, as well as driving Class III (SELV) luminaire parts
in independent installation with external strain relief.
• If used inside
Class I
luminaires, the earth cable is recommended
to be connected to improve the EMC performance of the driver,
but it is not mandatory. It is the responsibility of the integrator
to ensure that the assembled luminaire EMC performance
complies with the latest standards. Driver RFI measurement
data will be provided by request.
• If used inside
Class II
luminaires, the safety of the luminaire shall
be ensured through double/reinforced insulation of live parts.
LC45iC-DA-100-900
has double/reinforced insulation between
accessible and live parts, and is suitable for use in all Class II
luminaires. In this case the earth terminal of the driver must
be left unconnected and the luminaire terminal block shall not
have any protective earthing terminal.
• If used in
independent
installation with Class I/II/III luminaires,
the earth cable connection is optional. Please follow the
instructions provided in the strain relief datasheets.
Miniature Circuit Breakers (MCB)
• Type-C MCB’s with trip characteristics in according to EN 60898
are recommended.
• Please see more details in “MCB information” document in each
driver product page in “downloads & links” section.
Installation site
• The general preferred installation position of LED drivers for
independent use is to have the top cover facing upwards.
• Minimum recommended distances below:
• Suitable for installation upside down and in the corner, in this
case separate spacers must be used. For more information,
please consult Helvar.
Helvar Driver Configurator -support
LC45iC-DA-100-900 LED driver is supported by Helvar Driver
configurator software. The LC45iC-DA-100-900 driver supports
output current setting with software, the output current of the
driver can be programmed using Helvar Driver Configurator, as
well as OEM customer data and parameters for functions such as
CLO and Tunable White behavior. Programming the driver with
Helvar Driver Configurator can be done either wirelessly via NFC
or then via DALI bus.
