QUICKTRONIC

Intelligent DALI DIM | Additional properties of dimmable control gears from OSRAM

a) Upper limitation

The easiest way to achieve this is parallel switching of a

Zener diode with the corresponding value. A Zener diode

with a nominal value of 7 V must be used when limiting, for

example, to 7 V. Model Bzx 55C xVx can be recommended.

For xVx, for example, 7V5 equals 7.5 V. At least 20 ECGs

can be controlled with this model. In principle, the control

unit with the lowest value sets the speciﬁ cation for the

OSRAM DIM ECG when running parallel switching for mul-

tiple control units. This applies to all passive control units,

i. e. devices which represent a current sink.

b) Lower limitation

An effective lower limitation can be achieved through serial

switching of two control units. The sum of both devices is

effective. With one device, the control voltage speciﬁ cation

of the other device cannot be exceeded. Caution: The

smallest achievable control voltage amounts to approx. 2 V

(c. 4 % luminous ﬂ ux) when serially switching two control

units. The connections are to be made according to the

sketch.

4.6.3 Line length of the 1…10-V control line

The control line lengths are only limited by a drop in the

voltage. Overall, it can be said that a 100-m line length is

generally noncritical. The following formula can be used for

a more precise estimation:

e. g. at 1.5 mm², lighting strip, feed-in to start:

max

= 35 km/number of ECGs

= 350 m with 100 ECGs

= 700 m with 50 ECGs

Any line length may be used with DIM SA signal ampliﬁ ers.

4.6.4 1…10-V DIM ECGs and emergency lighting

Dimmable 1…10-V QUICKTRONIC

ECGs are suitable for

emergency lighting systems according to DIN V VDE V

0108-100 and DIN EN 50172. When using dimmable 1…10-

V QUICKTRONIC

ECGs in emergency lighting systems,

the control line should be disrupted in emergency operation

by suitable measures at the positive terminal. Correspond-

ing easy-to-wire toggle converters are available on the mar-

ket which send an adjustable control voltage to the OS-

RAM DIM ECG, thus enabling battery-friendly emergency

lighting operation at less than 100 % luminous ﬂ ux.

Some accessory components (e. g. DIM SA, DIM ICM 10

signal ampliﬁ ers) are not approved for battery operation.

Therefore, it must be ensured that these components are

never switched to a DC source. The signal ampliﬁ er, for ex-

ample, represents in this case a ﬁ xed resistor which is con-

nected to the control line. The dimmer setting of an ECG is

then about 20 %, and higher with more ECGs.

4.7 Terminals/cable cross sections/insulation

stripping length

Both single-core wires and ﬂ exible ones are permissible

for combination terminals for T5 and T8 ﬂ uorescent lamps

used in the QTi DALI/DIM. The terminal can be contacted

above via a so-called IDC (insulation displacement connec-

tor) and below via a plug contact (wire stripping 8.5–11 mm).

For ECGs with plug terminals (HF DIM, QTi T/E DALI/DIM),

both single-core wires (wire stripping 8.5–9.5 mm) and

ﬂ exible ones are permissible, provided they are zinc-plated,

sound-welded or equipped with wire-end ferrules.
