Description:
PSR250-12A1 is a 250W dual-input (AC/DC) hot-swappable power module designed for H3C S6520X-EI, S6805 series switches and compatible devices, featuring port-side intake and power module-side exhaust airflow (red latch). It supports wide-range AC input (90V-290V AC, 47/63Hz) and high-voltage DC input (180V-320V DC), delivering stable dual output (12V DC 20.9A, 3.3V DC 2A). With 1+1 redundancy, load balancing, and comprehensive protection, it enables hot-swap maintenance without system shutdown, ideal for enterprise networks, data centers, and high-availability environments requiring reliable redundant power backup.
