The LCC250-12U-4P is a 250 W fully-enclosed conduction-cooled AC-DC power supply delivering 12 V output at up to 20.8 A with IP64 protection against dust and water ingress. It features a wide input range of 90 to 264 VAC (47 to 63 Hz) and operates reliably across an extended temperature range of -40°C to +85°C baseplate temperature, with 89% typical efficiency at 230 VAC full load. The unit incorporates advanced protection features including overcurrent protection (=150% Io), overvoltage protection (110% to 135% Vo), and overtemperature protection with auto-recovery, along with differential remote sense capability and user-selectable output on/off logic. Ideal for outdoor signage, telecom installations (antenna and base station equipment), and indoor applications such as control consoles and medical desktops where the absence of cooling fans minimizes dust and noise.
