Uninterruptible Power Supply UPS Armac O/850F/LCD

The Armac O/850F/LCD is a line-interactive uninterruptible power supply (UPS) with a rated capacity of 0.85 kVA (450 W). Designed for office and small IT setups, it provides short-term backup power using a 12 V, 9 Ah battery and presents operational parameters on an integrated LCD panel for easy monitoring of input/output voltage, battery charge and operating mode. The compact black housing and two Type F AC outlets plus a USB Type-B port make it suitable for protecting essential devices against mains disturbances.

Advantages

This UPS includes an LCD control panel that displays current work parameters and status information. A built-in CPU automatically adjusts and stabilizes voltage within safe limits, responds to spikes and sags, prevents battery deep discharge and enables automatic restart and charging after mains recovery. It also features surge protection for data lines via two RJ-45 ports and a USB port for device configuration and remote communication with PowerManager software. A quiet-operation mode mutes non-critical sounds when running on battery power.

Suitable for

• Desktop PCs and workstations requiring short-term power backup
• Network equipment and small office servers
• Point-of-sale terminals and cash registers
• Home office setups and peripherals (modem, router, switch)

How to use

Connect critical equipment to the two Type F outlets and attach network lines to the RJ-45 ports if surge protection for data lines is required. Use the USB Type-B port to connect the UPS to a PC for configuration and monitoring via PowerManager software. The LCD panel provides live information about input/output voltage, battery charge and current operating mode. Ensure the UPS is placed in a ventilated location and connected to a grounded mains outlet before switching it on.

Recommendations

For reliable operation, periodically test the UPS under load, keep the battery charged when mains power is available, and replace the battery according to the manufacturer’s service intervals or when runtime degrades significantly. Avoid placing the UPS in direct sunlight, humid environments or next to heat sources.
