Low voltage fixtures

The installation of low voltage fixtures requires a number of precautions. The power of the transformer must equal the sum of the powers of the fixtures (W), in other words, 4 fixtures of 50W each require a transformer of 200VA. In addition, the low voltage fixtures must be looped to the security transformer. The transformer requires installation as close to the fixtures as possible to avoid voltage drops. Because the current at 12V is 18 – 20 times greater than at 230V, special attention must be paid to the use of appropriate wiring. In order to protect secondary circuits against overload, they must be equipped with the appropriate fuses. In particular, the use of electronic transformers, which operate at high frequencies (30 – 50kHz), requires a wire less than 2m long to comply with radio interference limit values. Dimming the current in low voltage installations is only possible by means of a dimmer suitable for the relevant transformer. Conventional (magnetic) transformers (operating frequency 50 – 60Hz) require a dimmer for inductive loads. Electronic transformers on the other hand normally require a dimmer for capacitive loads (turn-off controlled or phase control on the trailing edge, using a mosfet scheme). In some cases, by using an additional filter, in series with the electronic transformer, an inductive dimmer may also be used. In any case the dimmer should never be loaded under the minimum power or be overloaded. The instructions which come with the dimmer must be carefully read and strictly followed.
