OSRAM HALOTRONIC-COMPACT – HTM, HTN - Manual

Electronic transformers for 12 V
halogen lamps
• Optimum lamp life
• Compact for small spaces
• Reversible switch off in case of short-
circuits, overload and overtemperature
• Dimming on the primary side is
possible. A corresponding dimmer
has to be used (suitable dimmers see
table)
Connecting the transformers to the
lamps
• Ensure that the lamp load is within the
output range of the transformers (see
table)
• Transformers can be connected in
parallel on the primary side (fig. 1a)
• Do not connect the transformers in
parallel or series on the secondary
side (fig. 1b)
• The maximum load of the transformer
can be connected to any of the lamp-
side terminal pairs (except HTL 225)
Wiring
• In accordance with the 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 and 3)
• 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 and 3: angles ≥ 90°).
Do not route cables along the
transformers
• 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 transformers close to the lamp
(minimum distance 0.3 m). Maximum
permissible ambient temperature must
not be exceeded (see table). Make sure
there is adequate space to avoid a
build-up of heat. In critical installations
the temperature at t
c
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 secondary
side
