LL50iC-DA-100-1200 LED driver is suited for built-in usage in luminaires. 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.
Current setting resistor
LL50iC-DA-100-1200
LED driver features a constant current output
adjustable via current setting resistor.
• An external resistor can be inserted in to the current setting
terminal, allowing the user to adjust the LED driver output
current.
• When no external resistor is connected, then the LED drivers will
operate at their default lowest current level.
• A standard through-hole resistor can be used for the current
setting. To achieve the most accurate output current it is
recommended to select a quality low tolerance resistor.
Minimum diameter for resistor leg is 0.51mm.
• Always connect the current setting resistor only into the
terminals marked with LED-Iset on the LED driver label.
• For the resistor/current values, refer to the table on page 4.
LED driver earthing
• LL50iC-DA-100-1200
is LED driver suitable for Class I and II
luminaires. When used inside
Class I
and Class II
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.
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.
Helvar Driver Configurator -support
LL50iC-DA-100-1200 LED driver is supported by Helvar Driver
configurator software. The LL50iC-DA-100-1200 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. Also the operation of the multifunction LED-
Iset terminal usage can be changed from current setting resistor
(default) to NTC overtemperature protection operation.
Lamp failure functionality
No load
When open load is detected, driver will go to standby power
consumption and remains in automatic recovery mode. In automatic
recovery mode, the driver waits till load is returned and once that
happens, it returns to normal operation.
Short circuit
When short circuit is detected, driver goes to automatic recovery
mode and follows the same logic as described in the no load
condition.
Overload
When overload is detected, driver goes to standby mode and returns
through mains reset.
Underload
When undervoltage is detected, driver goes to standby mode and
returns through mains reset.
NTC trigger
When NTC is enabled via Helvar Driver Configurator, driver follows
NTC feature behaviour. Default NTC trigger point is 8,2 kΩ, after
which the driver starts to decrease the output level.
Switch-Control 2
Use of Switch-Control functionality
• Maximum numbers of LED drivers to be connected to one switch
is 60. Wire length is not restricted by the driver technology.
• Ensure that all components connected to Switch-Control
circuitry are mains rated.
