The PS3V-050AF12C is a 50W compact switching power supply designed for industrial control panels and factory automation equipment. It accepts a wide input voltage range of 100 to 240V AC (50/60 Hz single phase) and delivers a regulated 12V DC output at 4.5A, with output voltage adjustable within ±10% via the V.ADJ control. The unit features integrated overcurrent protection with automatic reset, overvoltage protection, and a green LED operation indicator. It operates reliably across -25°C to +70°C ambient temperature, includes dielectric isolation of 3000V AC between input and output, and is housed in a compact horizontal terminal type enclosure with M3.5 terminal screws. This power supply is ideal for warehouse storage facilities, machine tools, semiconductor manufacturing equipment, and multilevel parking systems where space is limited and stable power delivery is critical.
