TRANSFORMERS
FOR LOW-VOLTAGE
HALOGEN INCANDESCENT
LAMPS
The operating voltage of low-voltage halogen lamps is normally
12 V (6 and 24 V are also used for special applications). As a
result, transformers are required in order to connect such lamps to
the normal mains supply within buildings, whereby international
requirements governing building installations specify that safety
transformers or converters (electronic transformers) be exclusively
used for such purposes nowadays. These devices are designed in
such a way as to prevent both personal injury and the outbreak
of fire should the lighting system malfunction.
Electronic converters
The following chapter provides an overview of the VS range of electronic
converters that feature a whole range of advantages: light and
compact, superior efficiency (approx. 95%), short-circuit protection,
integrated overheating and overload protection, soft start for longer
lamp life, broad part-load range and dimmability.
Electromagnetic safety transformers
The following chapter also provides an overview of Vossloh-
Schwabe's range of electromagnetic transformers. The range is
split into protection class II transformers and protection class I
built-in transformers whose ultra-flat design make them particularly
user-friendly. Lamp brightness can be regulated using conventional
phase dimmers for low-voltage halogen lamps.
