Features

500 VA / 300 W Power Capacity: It delivers up to 500 VA (300 W) of backup power, making it suitable for desktop computers, routers, modems, CCTV systems, and other small electronic devices.
Line-Interactive Topology: The UPS uses line-interactive technology to regulate voltage fluctuations without switching to battery power immediately, helping to extend battery life.
Automatic Voltage Regulation (AVR): Built-in AVR automatically corrects low and high voltage conditions without using the battery, protecting equipment from brownouts and over-voltage damage.
Battery Backup During Outages: When mains power fails, the UPS instantly switches to battery power within milliseconds to keep connected devices running long enough for a safe shutdown.
Three IEC C13 Battery-Backed Outlets: It provides three IEC C13 outlets that supply both surge protection and battery backup to connected equipment.
Surge Protection: The unit protects connected devices from power surges and spikes caused by lightning or unstable electrical supply.
Sealed Maintenance-Free Battery: It uses a sealed lead-acid battery that requires no regular maintenance under normal operating conditions.
LED Status Indicators: Front-panel LED lights clearly show power status, battery mode, overload conditions, and faults.
Audible Alarms: The UPS provides sound alerts to notify users of power outages, low battery, or overload situations.
Compact Tower Design: Its compact vertical design saves desk or floor space, making it ideal for home or small office environments.
