SAI PowerWalker VI 1100 CW FR, Line-Interactive, 1,1 kVA (770 W), LCD, EPO, RS-232

The PowerWalker VI 1100 CW FR is a line-interactive uninterruptible power supply (UPS) with pure sine wave output, designed to protect sensitive electronic equipment from power disturbances. With an output capacity of 1.1 kVA (770 W) and built-in AVR for voltage stabilization, it delivers clean and stable power for home, office, IT and high-end PC systems. The unit includes a comprehensive LCD display and programmable outlets for flexible power management, plus multiple communication options including USB (HID) and an optional network card (SNMP).

Advantages

This UPS provides pure sine wave output and automatic voltage regulation to maintain stable voltage under fluctuating mains conditions. The integrated LCD offers clear real-time status and configuration information, while programmable outlets allow selective shutdown or extended runtime for critical devices. Multiple communication interfaces enable monitoring and safe shutdown via software or network management when the optional SNMP card is installed. Compact dimensions and 11.6 kg weight make it suitable for rack or tower placement in small environments.

Suitable for

• Home and small office desktop systems
• Sensitive IT and network devices (routers, switches, modems)
• High-end personal computers and workstations
• Peripheral equipment requiring clean sine wave power (storage, NAS)

Key specifications

• Output power capacity: 1.1 kVA
• Output power: 770 W
• Topology: Line-interactive with pure sine wave output
• Voltage regulation: AVR (automatic voltage regulation)
• Display: LCD for status and configuration
• Communication: USB (HID and software) and optional SNMP network card
• Dimensions (W×D×H): 145 × 397 × 220 mm
• Weight: 11.6 kg

How to use

Place the UPS on a stable, ventilated surface and connect the incoming mains supply. Attach critical devices to the programmable outlets and non-critical equipment to remaining outlets according to your runtime priorities. Use the LCD to review status, configure outlet programming and set alarms. For full monitoring and graceful shutdown, connect the UPS to a computer via USB and install the vendor software, or use HID mode for basic communication without drivers. Install the optional SNMP card if network monitoring or remote management is required.

Recommendations

For reliable protection, test the UPS after installation and periodically verify battery health. Configure programmable outlets to prioritize essential equipment and enable software-based shutdown to prevent data loss during prolonged outages.
