: This stage manages the incoming 100V–240V AC. It includes a safety fuse, varistors for surge protection, and a series of X and Y capacitors and chokes to filter out electromagnetic interference (EMI). Power Factor Correction (PFC) Adp-200er Schematic

The is more than just a wiring diagram; it is a roadmap to understanding Delta’s engineering philosophy. The design—featuring a front-end PFC based on the L6561 followed by a robust flyback converter—is a textbook example of medium-power SMPS design. [AC Input 100V-240V] ──> [EMI Filter & Protection]

The large 400V-rated primary electrolytic capacitor can retain lethal voltage long after the PSU is unplugged. Always verify the voltage across its terminals using a multimeter. If charged, safely discharge it using a high-wattage resistor (e.g., a 1k Ohm, 5W resistor)—never spark it out with a screwdriver. The design—featuring a front-end PFC based on the

The PFC stage ensures efficiency. The ADP-200ER uses a PFC choke, diode, and switching transistor to boost the raw DC to approximately , supplying the main converter.
