Rack Online UPS electro base UPS-OnR-1000-Pro 1000VA 900W, 2×9Ah internal batteries

Rack Online UPS electro base UPS-OnR-1000-Pro delivers 1000VA (900W) continuous power in a compact rack-mountable form factor with two internal 9Ah batteries. It provides online double-conversion topology for continuous clean sine wave output, automatic voltage regulation (AVR) and fast transfer to battery to protect servers, network devices and other critical IT loads from outages, brownouts and voltage fluctuations. The unit is designed for small racks, network closets and office infrastructure where uninterrupted power and orderly shutdown procedures are required.

Advantages

The UPS offers true online double-conversion operation to isolate connected equipment from input power disturbances and deliver a stable output voltage. Built-in automatic voltage regulation reduces the need to run on battery during minor input deviations. Internal sealed lead-acid batteries provide immediate backup without external battery cabinets, and hot-swap or serviceable battery access simplifies maintenance. Rack form factor and standard mounting options support integration into compact server and network racks.

Suitable for

• Small server racks and single-rack servers
• Network switches, routers and firewalls in data closets
• Storage devices and NAS systems requiring clean power
• Office workstations and point-of-sale terminals that need orderly shutdown
• VoIP gateways and communications equipment

How to use

Install the UPS into a compatible rack space following the rack-mount instructions, secure the chassis, and connect input power to a dedicated mains outlet. Connect protected equipment to the UPS output sockets and configure load priorities if available. Ensure the internal batteries are charged before relying on battery backup; many units charge automatically when mains power is present. Monitor the UPS status indicators and, where supported, connect to management software or USB/serial interface for event logging and automatic shutdown configuration.

Usage recommendations

Place the UPS in a well-ventilated environment, avoid high humidity and temperatures above operating limits, and provide periodic battery tests and replacements according to runtime requirements. Calculate total connected load to remain within the 900W continuous rating, and allow headroom for peak currents to ensure stable operation and expected battery runtimes.
