    The input circuitry passes Input AC through a No-Fuse Breaker (NFB), an EMI Filter, and Inrush Control. The Bridge Rectifier converts the AC into a pulsating DC current, which the Active Power Factor Control (PFC) circuit, which reduces the reactive current component to efficiently manage input power.
