• When the TV screen instantly switches from dark scenes to bright scenes, or when high-power audio is activated, the power board instantly delivers the required high current to prevent screen flickering, juddering, or sound distortion.
• Featuring a wide input voltage range, it operates stably whether in remote areas with unstable power or during grid fluctuations caused by thunderstorms, effectively protecting the entire TV unit.
• Utilizing large-area heat sinks, metal thermal plates, or thermally controlled fans, it maintains low operating temperatures even under heavy loads. Lower temperatures translate to extended component lifespan and enhanced TV durability.
• Built-in multiple safety mechanisms including overvoltage protection, undervoltage protection, overcurrent protection, overload protection, and short-circuit protection. In abnormal situations, it automatically cuts off power to prevent damage to core components.
