POWERTRONIC
® PTi and PT-FIT ECGs have been devel-
oped for indoor applications and for these they are suitable.
Any guarantee claims against OSRAM POWERTRONIC ®
PTi and PT-FIT ECGs are void if they are used in outdoor
areas – no matter what the IP classifi cation of the installed
luminaires may be.
PTi and PT-FIT devices conform to the requirements of
IEC/EN 61547: Resistance to interference under surge
voltage between L and N 1 kV, between L/N and PE 2 kV
for devices with input power > 25 W, with these values
divided by two where power is < 25 W. These levels of
test precision (test levels) comply with installation classes
2 (< 25 W) and 3 (> 25 W) in accordance with
IEC/EN 61000-4-5 Annex A.
Comparison of CCG and POWERTRONIC ®
Magnetic control gear (CCG) POWERTRONIC ® electronic control gear
Energy consumption 100 For indoor applications: 10 to 15 % savings over
the whole service life
For outdoor applications: up to 30 % savings over
the whole service life through dimming function (3DIM)
Lamp life 100
Up to 30 % depending on lamp type and
application
Lamp warm-up Depends on lamp type: generally approx. 60–90 sec,
up to 90 % of nominal luminous fl ux Up to 50 % faster
Color stability (HCI/HQI) Color variation possible Substantially improved color stability; both initially and over the
whole service life
Shutdown at end of
lamp life None or only primitive shutdown mechanisms Continuous parameter control, intelligent shutdown mechanisms
Shutdown of ignition Only with timer-based ignition devices Default shutdown of ignition after 20 minutes
Light fl icker Visible fl icker Flicker-free thanks to operation at 100–240 Hz
Power constancy Increased wattage over the whole service life, wattage also
depends on temperature and mains voltage fl uctuations
and cable length ± 3 % over the whole service life, independent of temperature,
mains voltage fl uctuations and cable length
Usability 3 components, complex wiring 1 device, simple wiring
Size and weight Heavy, more components, can be quite large Lightweight and compact
Power factor correction (PFC) 0.5–0.95, substantial fl uctuations due to age ≥ 0.95
Noise generation Possible detectable humming Almost soundless
Bi-directional data exchange Not possible Generally possible (DALI ® )
Dimming Possible to a limited extent (additional components necessary) 3 different dimming modes possible for outdoor ECG
(DALI
® , StepDIM and AstroDIM)
Lightning protection Not necessary For outdoor ECG up to 10 kV
The above values and statements are based on research and experience with OSRAM POWERTRONIC ® devices and are therefore not
trans ferable on a one-to-one basis to the devices made by other manufacturers.
POWERTRONIC ® PTo ECGs were developed for deploy-
ment in outdoor areas. Due to their robustness, they offer
substantial improvements in the way they deal with out-
door weather conditions (e.g. moisture or temperature
changes), vibrations or also transient power supply con-
ditions (caused by switching or lightning (EN 61000-4-5
Section 1). Besides street lighting, PTo ECGs can be used
in industrial applications. Both areas of application make
tough demands for surge voltage stability. PTos exceed
the standards required for Installation Class 4, with test
levels for L to N of 3 kV and for L/N to PE of 4 kV.
