The Battery Backup Adaptor is used to supply power to our Biometric Devices/Card Readers so that it can work without any barrier of power failure. It is connected with the switch and thus it will continuously provide the power. But after a power failure, it can provide power with its built-in battery for 4 to 6 hours. It features a battery charging indicator, if it glows Red then it shows charging mode, while green confirms the fully charged status.
A Battery Backup Adaptor is a power accessory designed to keep compatible biometric attendance machines and card readers operating during a power failure. It continuously supplies power when connected to the main electrical supply and automatically provides battery power when the main supply is interrupted.
The Star Link Battery Backup Adaptor can provide approximately 4 to 6 hours of backup after a power failure. Actual backup time may vary depending on the connected device and its power consumption.
The Battery Backup Adaptor is designed to provide backup power to compatible biometric devices and card readers. It can help keep attendance and access-control devices operational when the main power supply is unavailable.
The Star Link Battery Backup Adaptor provides 12V DC output at 1000mA (1A). The connected biometric or card-reader device should be compatible with these electrical requirements before installation.
The adaptor uses a Li-ion battery rated at 1150mA and 11.1V. The battery is built into the adaptor and provides backup power when the main electricity supply fails.
During normal operation, the adaptor receives power from the main electrical supply and continuously powers the connected device. When a power failure occurs, the built-in battery automatically takes over to help keep the connected biometric or card-reader device running.
The Battery Backup Adaptor includes a battery charging indicator. A red light indicates charging, while a green light indicates that the battery is fully charged.
A Battery Backup Adaptor helps reduce interruptions to biometric attendance and access-control operations during short-term power failures. This can be useful in offices, factories, warehouses and other workplaces where employees need to record attendance or access controlled areas without unnecessary downtime.
Both solutions provide backup power, but they are different products designed for different requirements. The Battery Backup Adaptor is a compact backup solution for compatible biometric devices and card readers, while a Power Supply with Battery Backup is a higher-capacity power solution intended for compatible biometric, security and access-control equipment.
Check the biometric device’s required input voltage, current, connector and power consumption before selecting the adaptor. Star Link’s Battery Backup Adaptor provides 12V DC/1000mA output and approximately 4–6 hours of backup, so compatibility should be confirmed before installation.
