Electronic Transformer with DALI ®
interface for 12 V halogen lamps
Features
• Dimmable via DALI
® interface
(according to DALI ® standard) or
TouchDIM ® or TouchDIM ® Sensor
• Suitable for emergency installation
• Reversible switch off in case of short-
circuits, overload and overtemperature
• Compliance with all relevant standards
Connecting the transformer
to the lamps
• Ensure that the lamp load is within the
output range of the transformer (see
table)
• Transformer can be connected in
parallel on the primary side (see
fig. 1a)
• Do not connect the transformer in
parallel or series on the secondary
side (see fig. 1b)
Wiring
• In accordance with EN 60598 standard,
the recommended connecting cables
(see table) must be held firmly by the
cable clamp to prevent it from being
pushed or pulled
• Secondary side: cable length maximum
2 m, minimum 0.3 m (fig. 2)
• To prevent radio interference keep lamp
cables as short as possible, keep them
away from metal surfaces and keep
them separated as far as possible from
mains cables (fig. 2: angles ≥ 90°). Do
not route cables along the transformer
• When using single leads of a cable,
secondary wires have to be twisted in
pairs
• For units installed in fixtures the
luminaire manufacturer is responsible
for RFI-compliance
Temperatures
• Avoid high temperatures. Do not place
the transformer close to the lamp
(minimum distance 0.3 m). Maximum
ambient temperature must not exceed
50 °C. Make sure there is adequate
space to avoid a build-up of heat. In
critical installations the temperature at
tc has to be controlled.
Caution
• Transformers must be installed by
a qualified electrician
• Electronic transformers are not suitable
for any other load than low voltage
halogen lamps
• No switching or dimming on the
secondary side
General hints
• Do not use DALI
® control and
TouchDIM ® or TouchDIM ® Sensor
simultaneously (see fig. 4 and 5)
• In case of emergency installation it is
recommended to short-circuit the
DALI
® interface (e.g. with a relais) while
emergency operation.
