Transformers are essential devices for the safe and efficient conversion of electrical voltage. They enable electricity to be transferred between different voltage levels and ensure that devices and systems are reliably supplied with the right voltage. Transformers are used in numerous areas - from household appliances to industrial systems to outdoor lighting and swimming pool technology. Whether for converting 220 V to 12 V in lighting systems or for supplying complex machines, transformers are indispensable components in power distribution and safety.
