Abstract

This utility model discloses a choke tuner with isolation circuit, relating to the field of tuner technology. It includes a tuner housing, a capacitor, a choke coil assembly, and a display screen. The capacitor is installed inside the tuner housing, and the choke coil assembly is disposed on one side of the capacitor. The display screen is fixedly embedded in the upper surface of the tuner housing. The corners of the tuner housing are chamfered. The capacitor has an electrical specification of 20uF / 1000V, and forms an LC resonant circuit through an inductor. The tuner housing is made of FV-2 flame-retardant material with insulation class F and high-temperature resistance class F, effectively preventing fire risks. The surface of the housing is treated with chromate passivation zinc plating to form an anti-oxidation colored film, enhancing corrosion resistance. The use of a 20μF / 1000V capacitor paired with a high-saturation-current inductor meets the requirements of high-current applications, improves energy transmission efficiency, and enhances the safety of the tuner.
