8. Dimming operation
– QUICKTRONIC® units that can be dimmed have the
letters …DIM in their references. They are dimmed
via the 1…10 V interface (QTi-…DIM), or via the DALI
interface (QTi DALI … DIM) or via Touch DIM® (also
with QTi DALI … DIM), see page 10.10 f. For special
technical data, such as wiring and associated control
components, please refer to the technical guide for
QUICKTRONIC® DALI/DIM. Allow new lamps to burn
in for 100 hours at 100% luminous flux since only after
this time will they exhibit stable values. A master/slave
circuit (one ECG for two separate luminaires with wiring)
is not permitted for dimmable ECGs.
– HALOTRONIC® can be controlled with various dim-
mers (see page 9.73) or dimming modules (see page
9.78). Since the interface between the dimmer and the
electronic transformer is not standardized, there may be
malfunctions in individual cases.
– POWERTRONIC® PTo 3 DIM units enable metal halide
lamps with ceramic burners and also sodium vapor
lamps to be dimmed. Dimming is performed via the
DALI interface, StepDIM 2-stage phase control or au-
tonomously via the internal AstroDIM control system of
the ECG. Details on dimming HID lamps can be found
in “Technical information on power reduction for high-
intensity discharge lamps” (www.osram.com).
– OPTOTRONIC® ECGs offer the following interfaces for
dimming: 1…10 V, DALI, leading-edge/trailing-edge
phase dimmers, 3DIM and 4DIM. The minimum dim-
ming value depends on the type of device. In addition,
some ECGs offer the option of operating MULTI3
sensors directly on the device.
Constant voltage LED ECGs can be expanded with
appropriate DIM modules (p. 9.24 ff).
9. Fixtures with ECGs
The following general points apply to luminaires with
electronic control gear:
– The temperature limits of the ECGs regarding ambient
temperature and measuring point temperature on the
ECG must not be exceeded (see 10. Ambient and ECG
temperatures).
– The maximum permissible radio interference suppres-
sion values (EN 55015) must not be exceeded. Make
sure the protective conductor and the function earth are
correctly connected. Running the lamp cables and pro-
tective conductor together (e.g. NYM cables) may lead
to problems due to high-frequency interference.
– After being installed or replaced, the lamps must be
burned in at full load for 100 hours to stabilize the
discharge process.
10. Ambient and ECG temperatures
The temperature ranges specified for the relevant control
gear must be maintained to enable the ECG to operate
reliably. Generally speaking, lower operating temperatures
can extend the life of ECGs.
When ECGs are built into luminaires the measuring point
temperature tc on the casing is the crucial parameter. The
maximum permissible value specified for the ECG con-
cerned must not be exceeded.
Installation and operating instructions
11. ECGs for outdoor fixtures
ECGs for high-intensity discharge lamps (PTo) and de-
vices for LED modules (OT…E and OT…P) have been
designed specifically for outdoor applications. They are
specially equipped for such applications; for example
protected against moisture, AC voltage peaks and vibra-
tions (wind load, rail vehicles).
When using ECGs in outdoor luminaires it must be ob-
served that the ECG may be exposed to humidity.
1. For luminaires of protection class 5 (protected against
water jets, IP65 for example) standard ECGs can be
used since moisture cannot penetrate this type of
luminaires, so there is little chance of ECG corrosion.
In individual cases the use of supplementary protective
measures must be considered (e.g. use of OUTKIT).
2. For luminaires of protection class 3 (protected against
splash water, IP43 for example) it is likely that water
droplets will penetrate and thus cause corrosion
and failure of unprotected standard ECGs. In cases
of doubt (e.g. bollard luminaires, outdoor displays),
additional protective measures should be taken such
as using OUTKIT (see page 9.79).
12. Wiring of ECGs
Parallel connection of HALOTRONIC® and OPTOTRONIC®
(with the exception of OT 75/220-240/24 [E], OTe 90/220-
240/4x350 E and OTe 90/220-240/4x500 E) is not
permitted on the secondary side. Series connection of
HALOTRONIC® and OPTOTRONIC® to increase the
voltage or for voltage matching is not permitted on the
secondary side, unless specifically indicated in the data
sheet. Lamp-side switching or dimming is not permitted.
The only permitted loads for electronic transformers are
low voltage halogen lamps. For details see the Technical
Guides.
13. Lifespan and reliability of ECGs
The failure rate of electronic components depends not
only on the component specification and quality but
also very considerably on the operating temperature.
OSRAM’s ECGs are designed so that at the maximum
permissible ECG temperature (tc max.) a failure rate of
fewer than 2 per thousand ECGs per 1000 hours of op-
eration can be expected. This corresponds to an ECG life
of 50,000 hours at a percentage ECG failure rate of 10%.
In practice it can be assumed that at a temperature 10 °C
less than the maximum permitted temperature (t c ), the life
of an ECG is doubled.
The following have different lifespans:
1. up to 30,000 hours for QUICKTRONIC® QT-ECO and
DULUXTRONIC®, HALOTRONIC® HTM MOUSE® and
HTN at a failure rate of 10%
2. QT ENDURA with up to 60,000 hours at 10 % failure rate
3. up to 30,000, 50,000 or 85,000 hours for OPTOTRONIC®
depending on version, at a failure rate of10%
4. POWERTRONIC® PTo with up to 60,000 hours at 8 %
failure rate, POWERTRONIC® PTi with up to 50,000
hours at 10 % failure rate, POWERTRONIC® PT-FIT
with up to 30,000 hours at 10 % failure rate
