The Power Personal is an affordable standby UPS solution designed to protect electronic devices from brief blackouts, brownouts, and surges, which can lead to downtime, revenue and data loss, hardware damage, and workflow interruptions. The UPS monitors incoming voltage, instantly switching over to battery power when it detects a power disturbance outside the acceptable range to continue to provide power to connected devices to minimize downtime and maximize productivity while safeguarding your electronics. The adaptable wall-mountable design allows for versatile installation options: wall-mount, desktop, or rack-mount.
