LED Driver
Constant voltage
7.2 Conditions of use and storage
Humidity:
5 % up to max. 85 %,
not condensed
(max. 56 days/year at 85 %)
Storage temperature:
-40 °C up to max. +80 °C
The devices have to be acclimatised to the specified temperature range (ta)
before they can be operated.
The LED Driver is declared as inbuilt LED controlgear, meaning it is intended
to be used within a luminaire enclosure.
If the product is used outside a luminaire, the installation must provide
suitable protection for people and environment (e.g. in illuminated ceilings).
7.1 Insulation and electric strength testing of luminaires
Electronic devices can be damaged by high voltage. This has to be considered
during the routine testing of the luminaires in production.
According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A,
each luminaire should be submitted to an insulation test with 500 V
DC
for
1 second. This test voltage should be connected between the interconnected
phase and neutral terminals and the earth terminal.
The insulation resistance must be at least 2 MΩ.
As an alternative, IEC 60598-1 Annex Q describes a test of the electrical
strength with 1500 V
AC
(or 1.414 x 1500 V
DC
). To avoid damage to the electronic
devices this test must not be conducted.

Technical Data
Lifetime declarations are informative and represent no warranty claim.
No warranty if device was opened.
7.3 Maximum number of switching cycles
All LED Driver are tested with 50,000 switching cycles.
The actually achieved number of switching cycles is significantly higher.
7. Protective features
7.2 Intelligent Voltage Guard (IVG)
The Intelligent Voltage Guard (IVG) function warns of possible damage due
to overvoltage or undervoltage.
The mains voltage is constantly monitored and if necessary appropriate
responses are made:
• If the mains voltage is too low (< 70 V), the LED Driver is switched off.
• At a mains voltage between 70 and 140 V, the LED Driver switches off and
on again on a non-cyclic basis.
• In case of an overvoltage (> 318 V), the LED Driver sends feedback via
DALI.
7.6 Insulation between terminals
7.3 Short-circuit behaviour
In case of a short-circuit at the LED output the LED output is switched off.
After restart of the LED Driver the output will be activated again. The restart
can either be done via mains reset or via interface (DALI, DSI, switchDIM,
ready2mains)
7.5 Overload protection
If the maximum load is exceeded by a defined internal limit, the LED Driver
turns off the LED output. After restart of the LED Driver the output will be
activated again.
The restart can either be done via mains reset or via interface (DALI, DSI,
switchDIM, ready2mains).
7.4 No-load operation
The LED Driver will not be damaged in no-load operation. The output will
be deactivated and is therefore free of voltage. If a LED load is connected the
device has to be restarted before the output will be activated again.
7.1 Intelligent temperature guard (ITG)
The Intelligent temperature guard (ITG) function provides effective protec-
tion against thermal overloads by slowly reducing the output if a defined
internal temperature is exceeded.
The reduction of overtemperatures takes place in small steps every two
minutes. As soon as the temperature drops again, the output power is gradu-
ally increased every 10 minutes.
On DC operation this function is deactivated to fulfill emergency
requirements.
