Product information

Description

The APC Back-UPS BK350EI is an uninterruptible power supply designed to protect office systems and important data from power surges, spikes and blackouts. It includes six power outlets, five of which offer battery backup and one that provides surge protection only. The unit also supplies data-line protection via an RJ45 analog phone connection suitable for phone, fax, modem or DSL lines. Dimensions are 16.5 x 9.1 x 28.4 cm and the weight is 6.32 kg, with an estimated runtime of 14 minutes 52 seconds at a 100 W load.

Advantages

The BK350EI combines battery backup and surge protection in a compact form factor to maintain power to connected equipment during outages and to suppress harmful voltage spikes. Multiple UPS-backed outlets allow safe shutdown of essential devices while a dedicated surge-only outlet is available for non-critical equipment. Integrated data-line protection reduces the risk of damage to communication devices connected via an RJ45 analog phone line.

Key specifications

  • Model family: Back-UPS (BK350EI)
  • Number of outlets: 6 total (5 battery backup + 1 surge-only)
  • Runtime at 100 W: 14 minutes 52 seconds
  • Data-line protection: RJ45 analog phone line (phone/fax/modem/DSL)
  • Dimensions: 16.5 x 9.1 x 28.4 cm
  • Weight: 6.32 kg

How to use

Place the BK350EI on a stable, ventilated surface near the devices to be protected and connect important equipment to the UPS-backed outlets and non-critical devices to the surge-only outlet. Plug the RJ45 data line into the provided port to enable phone/fax/modem/DSL protection. Start connected equipment and monitor the UPS status indicators to confirm normal operation. In the event of a power outage, the UPS will supply battery power to devices plugged into the battery-backed outlets until the battery is depleted or power is restored.

Recommendations

For reliable protection, regularly test the UPS and replace the battery according to the manufacturer's maintenance schedule. Use the battery-backed outlets for critical office equipment such as desktop PCs, external drives and network devices that require controlled shutdown during extended outages.
