GÜDE EPB 8810-1 USV Expert Power Backup Tower/RM – online-UPS

For critical IT infrastructure, the GüDE EPB 8810-1 USV Expert Power Backup delivers true online double-conversion protection, completely isolating connected equipment from utility power anomalies. Unlike line-interactive units that switch to battery only when voltage sags, this UPS continuously regenerates a pure sine wave output, making it ideal for servers, network storage, and sensitive electronics. Its 2U rackmount/tower convertible chassis fits neatly into standard 19-inch racks or stands upright on a desk, while the 1000 VA / 900 W capacity supports a small server room or high-end workstation cluster.

Highlights

• Online double-conversion topology with zero transfer time to battery
• Pure sine wave output for compatibility with active PFC power supplies
• Selectable output voltage (200/208/220/230/240 VAC) and auto-sensing frequency
• Three IEC C13 outlets for direct connection of critical loads
• LCD display for real-time status, load, and battery information
• USB and RS-232 ports plus intelligent slot for optional SNMP/relay card
• ECO mode boosts efficiency up to 97% for less critical periods
• Hot-swappable batteries allow replacement without powering down connected equipment

In daily use

The EPB 8810-1 operates quietly at under 45 dB, suitable for office environments. Its automatic bypass ensures continuous power to loads even if the UPS encounters an internal fault, while the manual bypass facilitates maintenance without downtime. The included management software provides graceful shutdown for multiple servers over USB or serial, and the intelligent slot accepts an optional SNMP card for network-wide monitoring and alerts. With a recharge time of just 4 hours to 90% capacity, the UPS is quickly ready after an extended outage.
