LL60/2-E-DA-iC LED driver is suited for built-in usage in luminaires. With LL1x2135-SR strain reliefs, independent use is possible too (see
the LL1x2135-SR datasheet for details). 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
LL60/2-E-DA-iC 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 Iset on the LED driver label.
• For the resistor/current value selection, refer to the table on
page 4.
LED driver earthing
• LED drivers are designed to support different luminaire
classifications, such as Class I or Class II fittings (no earth
required). LL60/2-E-DA-iC is Class II driver and suitable for
Class I and II luminaires, as well as driving SELV Class III
luminaires in independent installation with strain reliefs.
• As Class II driver, LL60/2-E-DA-iC does not need the earth
connection for electrical safety. To improve e.g. EMC
performance, functional earth can be connected.
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.
Use of Switch-Control functionality
• Maximum numbers of LED drivers to be connected to one switch
is 30.
• The maximum cabling length from the switch to the driver is 25
meters. If longer cabling is needed, please connect a capacitor
across the Switch-Control input (1 μF, min. 275 VAC RMS and X2
rated, according to IEC 60384-14).
• Ensure that all components connected to Switch-Control circuitry
are mains rated.
• Switch-Control with this driver is only allowed to be used in Class
I luminaires

Helvar Driver Configurator support
LL60/2-E-DA-IC LED driver is supported by Helvar Driver
configurator software. The configurator allows user to control and
set the parameters for tunable white such as colour temperature
limit and lumen output on both channels. The linear dimming curve
can be enabled from the configurator as well.
