Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core).
The main functions of outdoor light transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. It is one of essential landscape lighting accessories for outdoor lighting. The main function is to convert a certain level of AC voltage and current into another level of voltage and current at the same frequency. Compare with garden lights transformer 120v 150w for you to choose.
