Safety isolating transformers, encapsuled in resin for supplying 12V- halogen lamps.
The transformers are constructed for an input of 230VAC. The nominal voltage of the
halogen lamps does not exceed, even with usual excess voltage. This means:
longer life of your halogen lamps.
For protection against inadmissible current load and short-circuit a changeable fuse
and a self-reseting thermal cut-out is incorporated.
The input- and output-connection by screw-terminals.
Suitable for built-in mounting on furniture or in lowered cellings.
With dimmer suitibility for regulation of the brightness.
