Uninterruptible Power Supply APC Back BX950MI-GR 950VA 540W

APC Back BX950MI-GR 950VA 540W is an uninterruptible power supply designed to provide temporary backup power and surge protection for home and small office electronic equipment. With a compact form factor and a combined 950VA / 540W capacity, this UPS helps maintain power to essential devices such as desktop PCs, routers and modems during short power interruptions and protects connected equipment from voltage spikes.

Advantages

The unit delivers both battery backup and automatic voltage regulation to reduce the risk of data loss and hardware damage caused by sudden outages and electrical disturbances. Its compact design facilitates placement near workstations or network equipment, while clearly marked outlets and simple operation make it suitable for non-specialist users. The UPS offers multiple outlets for simultaneous protection of several devices and uses a built-in battery that provides immediate switchover to backup power when mains fail.

Suitable for

• Home desktop PCs and monitors
• Small office workstations and network devices (routers, modems, switches)
• External hard drives and NAS devices for short safe shutdowns
• Peripherals such as printers and VoIP adapters during brief outages

Key specifications

• Output capacity: 950 VA / 540 W
• Topology: standby (offline) UPS with automatic transfer to battery
• Output waveform: simulated sine wave
• Typical runtime: short-term backup suitable for safe shutdown (varies with load)
• Form factor: compact tower design for desktop or floor placement
• Protection features: surge protection and battery backup for connected outlets

How to use

Place the UPS on a stable, well-ventilated surface, away from direct heat and moisture. Connect critical devices such as a PC, monitor and router to the battery-backed outlets and non-critical equipment to surge-only outlets if available. Plug the UPS into a grounded mains outlet and switch it on to charge the internal battery. During a power failure the unit will automatically transfer connected devices to battery power; monitor battery status and allow connected devices to perform a controlled shutdown if runtime is insufficient.

Usage recommendations

To maintain optimal performance, periodically test the UPS by simulating a power outage and replace the internal battery according to manufacturer guidelines or when runtime drops significantly. Keep firmware or management software updated if provided and avoid connecting high-power appliances that exceed the rated wattage.
