Light Management Tronic Transformers
Operating Instructions
Electronic transformers for lowvoltage
halogen lamps
1. Safety instructions
Attention: Electrical equipment must be installed and fitted by
qualified electricians only.
To prevent electric shocks, always shut off the mains supply (by
cutting out the circuit-breaker) before working on the device or
before replacing the lamp.
Any non-observance of the safety warnings and fitting instructions
may result in damage to the device and cause fire or other hazards.
2. Function
Use for 12 V halogen lamps.
The device can only be dimmed with JUNG TRONIC or Universal
dimmers.
Never use dimmers from other manufacturers.
Using dimmers from other manufacturers may involve a risk of fire.
Lamp-saving soft-start at switch-on (except for 40 W / 70 W Qu).
Overload and over-temperature protection by automatic reduction of
power (40 / 70 / 105 / 150 W transformers) or shut-off until device has
cooled down (70 W Qu and 200 W transformer).
Short-circuit protection (40 / 70 / 105 / 150 W transformers):
Shut-off with automatic restart after removal of short-circuit.

Light Management Tronic Transformers
Short-circuit protection (200 W transformer):
Shut-off with automatic restart if short-circuit is removed within 5
seconds. Thereafter, permanent shut-off until manual restart.
3. Fitting instructions
TRONIC transformers are protected against tansient overvoltages (mains
voltage peaks) in acc. with EN 61547. To protect them against higher
overvoltages (produced by the switching of fluorescent lamps, discharge
lamps, motors and other inductive loads) install a separate load circuit for
TRONIC transformers. The TRONIC transformer may otherwise be
damaged if the circuit is switched by peak voltages.If there is a risk of
mains voltage spikes, a overvoltage protection module must be used in
addition and connected on the primary side in parallel to the TRONIC
transformers (between L and N) fig. (2)a.If TRONIC transformers are to
be dimmed, the overvoltage protection module must be connected in
parallel to the series connection of dimmer and TRONIC transformers,
fig. (2)b.
Figure 2a
Figure 2b
1 overvoltage protection module is sufficient for about 10 TRONIC
transformers per circuit.
Observe the power rating limits of the transformers.
Insufficient loading may lead to flickering of the lamps connected.

Install and connect the transformers as shown in figure (1), (3) (keep
twice the distance between individual transformers) and figure (4).

Avoid sources of heat (e.g. lamps) in the immediate vicinity of the
transformer. In critical cases, measure the temperature at the Tc point.
Recommended cross-section and type of secondary cable, fig (5).
Secondary cable: see technical data, fig. (9).

110 W – 150 W ≥2,5 mm² z.B. H 05 V V-F 2 x 2,5 mm²
155 W – 200 W distribute power to at least 2 lines (min. 2 x 1,5
mm²)
Figure 5
If several lamp circuits are to be connected to a transformer, it is
recommended to use a distributor, fig. (6).
Figure 6
The secondary line must not be connected to the secondary line of other
TRONIC transformers and not be laid close to the mains supply line, fig.
(7).

Light Management Tronic Transformers
In TRONIC transformers without stress-relief, the cable must be
protected against pushing and pulling with a suitable clamp at the
TRONIC transformer.
For TRONIC transformers with prepared connecting cable, a suitable box
to connect the mains supply must be used.
For TRONIC transformers equipped with a stressrelieving device, use at
least a H 05 VV-F 2x1.5 mm² cable for the mains supply. Stripping length
for outer cable sheath and base insulation: see fig. (8).
Figure 8
Important: When TRONIC transformers with multipoint terminals on
the primary side for mains supply through-connection are used, the
maximum number of interconnected TRONIC transformers is limited
to 10.
