Step Down Voltage Convertor With International Socket For US Appliances 1 KVA 800W 220V To 110V
? A step-down AC voltage converter, as the name suggests, is a device designed to reduce the voltage level of alternating current (AC) power. Unlike step-up converters, which increase voltage levels, step-down converters are employed when the input voltage needs to be decreased. These converters are indispensable in scenarios where the available voltage exceeds the requirements of the connected load.
? The fundamental principle behind the operation of a step-down AC voltage converter lies in the use of transformers. Transformers consist of two coils of wire, known as the primary and secondary coils, wound around a shared magnetic core. When an AC voltage is applied to the primary coil, it induces a varying magnetic field in the core, which, in turn, induces a voltage in the secondary coil. The ratio of the number of turns in the primary and secondary coils determines the voltage transformation ratio.
? In a step-down transformer, the secondary coil has fewer turns than the primary coil. As a result, the induced voltage in the secondary coil is lower than the input voltage applied to the primary coil. This reduction in voltage enables the conversion of high-voltage AC power to lower voltage levels suitable for specific applications.
