IRPLHALO1E
Electronic transformers are commonly used in place of wire wound step down transformers in order to
provide the correct supply for low voltage (generally 12V) filament lamps such as Dichroic Halogen that
are widely used.
The advantages are:
1) Small size and weight
2) Fault protection circuitry
3) Safety because of low output voltage
(1) Throughout this data sheet “convertor” is spelled in accordance with standard IEC 61047 “DC or
AC supplied convertors for filament lamps – Performance requirements”.
Electronic transformers have become popular for low voltage lighting applications. The range of
products available ranges from very small 50W units, capable of driving only a single 50W lamp to
300W units capable of driving up to 6 X 50W lamps. In many applications the lamps are attached to
a track system in which the supply rails are exposed. Since the voltage is only approximately 12V
this does not present any safety problem.
The electronic transformer is generally smaller and lighter than a wire wound equivalent and may
be equipped with short circuit and thermal protection, which are generally not included when a wire
wound transformer is used. Generally a well-designed electronic transformer may be dimmed with
a triac based leading edge phase cut dimmer (as can a wire wound transformer) or by a trailing
edge transistor dimmer.
