TS 46365 OSRAM / POWERSTAR HQI 106_T001_GB 2/22.04.2009
Please note:
The values and curves published in this document are
for guidance only. The basic data was determined under
controlled laboratory conditions for a switching cycle of
11 h on/1 h off.
There may be considerable differences in actual practice.
PF correction capacitor:
The pf correction capacitors are designed so that
cos w > 0.9 is achieved at rated voltage.
Operating instructions
Supply voltage:
The lamps must be connected via suitable control gear. A
240 V / 50 Hz ac supply is generally required. If a different
supply voltage is used (e.g. 400 V / 50 Hz) control gear
with appropriate taps must be used.
Permitted mains voltage deviation: ± 3%
Sudden fluctuations in mains voltage of more than 10%
may cause the lamps to go out.
If the deviation from rated supply voltage (230 V or 400 V)
is permanent, high-pressure discharge lamps may exhibit
changes in colour or luminous flux. Lamp life may also be
reduced.
Control gear:
Conventional control gear: Choke, igniter and pf correc-
tion capacitor.
The right igniter for the particular lamp type must be used
to ensure reliable and safe ignition.
Igniters must always be installed close to the lamp.
The choke may be installed any distance from the lamp,
provided the permissible voltage drop is not exceeded.
For power supplies with a neutral conductor the choke
should be connected to the live conductor. In the case of
luminaires in which there are no lamps installed, the igni-
tion equipment (igniter, ignition pulser) must be disabled
when voltage is applied otherwise the igniters may pro-
duce radio interference.
The chokes and pf correction capacitors generally needed
for operating discharge lamps may, under certain condi-
tions, create oscillating circuits. These circuits may then
produce excessive currents and voltages, which in turn
can destroy the lamps, ballasts and capacitors. Such
resonance phenomena must be avoided by appropriate
circuits and fuses.
When high-pressure discharge lamps come to the end of
their lives a rectifier effect may occur (see IEC 62035).
This is not manufacturer-specific. Because of the exces-
sive dc current components the ballasts and igniters may
become overheated.
High-pressure discharge lamps should therefore only be
operated with control gear with thermal protection.
This applies also to control gear with the option of power
reduction.
The following lamps with integrated igniters don’t
need external igniter:
 c HQI
®
-T 2000 /D/I
 c HQI
®
-T 2000 /N
The lamps must not be operated with integrated igniters
in luminaires equipped with igniters.
Suitable igniters and control gear for POWERSTAR
®
are
available from the electrical industry.
Operation of HQI-TS Excellence at PT-TS ballast – which
are not produced or sold anymore for very long time – is
not permitted.
Operating temperatures:
Only high-pressure discharge lamps with external
igniters are suitable for low-temperature applications
down to – 50 °C. Such applications call for special
(heatable) igniters such as MZN 400 SU-LT from BAG
Turgi (for lamps from 100 to 400 W).
Power factor:
CCG: Because of the series connected choke this is
around 0.5 to 0.7 (without compensation)
ECG: If POWERTRONIC
®
is used the power factor is
greater than 0.96. Compensation is therefore not
needed here.
Switching on:
Full luminous flux is reached only a few minutes after the
lamp is switched on. The start-up current may be up to
twice the operating current depending on the control gear.
