More Information
Summary:An adapter of a light string assembly with a casing, a plug arranged on the casing, and an energy saving circuit 3 inside. The energy saving circuit has a filtration device 10, a rectifier 20, a power factor correction 30 (PFC), a transformer 40, and a feedback circuit 50. These are arranged from a voltage input end to a voltage output end of the energy saving circuit in order. The PFC is defined between the rectifier and the filtration device so as to obtain quasi-sine currents from a power, wherein the energy saving circuit has PFC with a line voltage. A value of a power factor is close to 1, such that the PFC adjusts and corrects a power factor by way of the transformer. This aims to reduce an input loss and save energy.
