Description:
PSR250-12A is a 250W dual-input (AC/DC) hot-swappable power module designed for H3C S6530X, S6805 series switches and compatible devices, with power module-side intake and port-side exhaust airflow (blue 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). The hot-swappable design allows maintenance without system shutdown, while 1+1 redundancy with load balancing ensures reliable operation, ideal for enterprise networks, data centers, and high-availability environments requiring dual-input power backup and seamless field replacement.
