Sorry, there was a problem. Please try again later.The APC BN450MNW is a compact uninterruptible power supply (UPS) designed for home and small office use, with a maximum output of 450VA / 255W. It provides battery backup and surge protection for connected devices like desktops, routers, and modem. Will It Prevent Shutdown During Generator Delay? Yes, the BN450MNW can prevent your desktop from shutting down during the several-second delay between a power outage and your backup generator starting, as long as: 1. Your desktop's power draw is within the UPS's capacity (255W max). 2. The generator delay is within the UPS's battery runtime. At full load (255W), the battery lasts approximately 2.5 minutes. If your generator starts within 10–30 seconds, the BN450MNW should easily bridge that gap.
