Protective class II
Protective type IP 20
Thermal class E
Nominal ambient temperature ta 40°C
Input voltage: 230 VAC
Output voltage: 11,5 VAC
Frequency: 50/60Hz
Non. inherently short-circuit
Test voltage PRI - SEC 4,5 kVAC
Two chamber winding
Resin moulded



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 has a 1,5m mains lead with a mounted Euro-plug. The output has a terminal,
or wires of 1m length.
Suitable for built-in mounting on furniture or in lowered cellings.
With dimmer suitibility for regulation of the brightness.
