Single-phase toroidal transformer of 160VA, input voltage 230Vac and two output windings of 12Vac, which can be connected in series to obtain an output of 24Vac and an intensity of 6.67A (apparent intensity), or in parallel to obtain an output of 12Vac and an intensity of 13.34A (apparent intensity).
This type of transformer is very suitable when reduced size and weight are required, with an improvement of up to 50% compared to other types of construction, very low copper losses under load, which translates into less overheating and high performance. Excellent no-load/load regulation and very low noise level. Very low magnetic radiation.
Annular magnetic core made of silicon-steel sheet with high permeability heat treatment and losses less than 1W/kg.
Mounting using 2 metal discs, insulating washers and screw (included in the supply).
Output threads with colour code identification, 25cm long.
The main application of this type of transformer is for command and control in industrial automation, power supplies and for general applications. They are intended to supply electrical devices where galvanic isolation between circuits is required.

Electrical connection
The secondary windings can also be used independently, in this case, the power available for each of the windings will be 50% of the total power of the transformer.
The transformer is supplied without any type of overload protection, it is mandatory to install such protection to avoid overloading the transformer. The power and intensity indicated are apparent, the active intensity provided by the transformer will depend on the power factor of the connected load.
In the case of using a protection fuse in the primary, it is recommended to use the delayed type, to absorb the high starting current characteristic of this type of transformer.
Professional use material, install in compliance with the regulations in force at the installation site.
