Battery Backup
Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.
Surge Protection
Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage.
CC/CV Charger
Built-in CC charger keep battery charged in Constant Current while charging.
Built-in CV charger keep battery charged in Constant Voltage after fully charged to ensure battery power.
