The CyberPower BU650EU UPS provides home and office users with reliable battery-supported backup and protects office PCs and other electronic devices from surges, voltage spikes, power outages, and other power irregularities. The product uses a line-interactive topology with automatic voltage regulation (AVR) to deliver a stable AC output.

The patented GreenPower UPS Bypass design helps the UPS achieve an extremely low power consumption to reduce energy costs while also lowering the operating temperature of the UPS, which extends battery life. A configurable alarm allows the user to turn the audible alarm on or off during battery operation to avoid unnecessary disturbances. Thanks to its desktop design, the device can be easily placed on a desk or in other tight spaces.
