Overview
- The APC Back-UPS BK650-AS is a standby UPS system purpose-built for small office and workgroup power protection. With 650VA capacity and 400W rated power output, it delivers sufficient backup runtime to safely shut down systems during mains failure or protect against power disturbances.
The unit features four IEC C13 outlets with three battery-backed and one dedicated surge-only outlet, accommodating typical office equipment configurations. The user-replaceable lead-acid battery (RBC17) eliminates service call delays and reduces total cost of ownership over the system lifetime.
Beyond power backup, the BK650-AS includes integrated data line protection for telephone, fax, modem and DSL connections via RJ45 connector, safeguarding communication equipment from voltage spikes. The stepped approximation sinewave output and wide input voltage tolerance (160–282V adjustable) ensure stable power delivery across variable Australian mains conditions.
Operating at just 45 dBA acoustic level, it remains unobtrusive in office environments. Supplied with USB cable, telephone cable, software CDs and two detachable IEC power cords (1.2m and 1.8m), the BK650-AS provides immediate deployment capability with minimal additional purchasing.

FAQs
How long will the APC Back-UPS BK650-AS keep my equipment running during a power outage?
At a typical office load of 100W, the unit provides approximately 35 minutes of backup runtime. Actual runtime varies depending on the total load connected—lighter loads will extend runtime, heavier loads will reduce it. For longer protection, consider a higher-capacity UPS model.
Can I replace the battery myself?
Yes. The APC Back-UPS BK650-AS features a user-replaceable lead-acid battery (RBC17). This design eliminates the need for costly service calls and allows you to extend the UPS lifespan affordably. Replacement batteries are readily available.
What is the difference between the battery-backed outlets and the surge-only outlet?
The three standard C13 outlets continue to provide power from the battery during mains failure, protecting connected equipment. The dedicated surge-only outlet provides surge and spike protection only, without battery backup—ideal for devices like printers that don't need continuous power during outages.
Does the BK650-AS protect telephone and internet equipment?
Yes. The unit includes an RJ45 data line protection port for telephone, fax, modem and DSL connections. This protects communication equipment from voltage spikes transmitted via phone lines, a common cause of equipment damage during electrical events.
What input voltage range does this UPS accept?
The BK650-AS accepts input voltages from 160V to 282V (adjustable), with a nominal range of 180–260V. This wide tolerance accommodates voltage variations common in Australian office environments without draining the battery or triggering shutdown.
Can the APC Back-UPS BK650-AS be rack-mounted?
No. The BK650-AS is a tower-format UPS designed for desk-side or floor placement in office environments. It is not suitable for standard 19-inch rack installations. For rack-mounted requirements, alternative APC UPS models should be considered.
What is included in the box?
The package includes the UPS unit, two detachable IEC power cords (1.2m and 1.8m), USB cable, telephone cable, software CD, documentation CD, and warranty card. Everything required for immediate setup and use is provided.
Is the BK650-AS noisy?
No. The unit operates at 45 dBA, which is relatively quiet and suitable for office environments where noise sensitivity is a concern. The fan only activates during battery discharge, further minimising acoustic impact during normal operation.
