APC Back-UPS Pro 1500VA Rack 1U Line-Interactive UPS

The APC Back-UPS Pro 1500VA Rack 1U (BR1500MS2) from Schneider Electric is a compact, line-interactive uninterruptible power supply engineered for space-constrained rack environments such as network closets, branch office server rooms, and edge IT deployments. Its line-interactive topology continuously regulates incoming voltage through automatic voltage regulation (AVR), correcting brownouts and overvoltages without drawing on battery reserves, which extends overall battery service life in environments with fluctuating utility power.

The BR1500MS2 provides 1500VA / 900W of output power capacity across ten NEMA 5-15/20R outlets, segmented into battery-backed and surge-only outlet groups, enabling administrators to prioritize runtime for critical loads while protecting secondary equipment from power surges. The unit ships in a 1U rack-mountable form factor and also supports tower orientation, offering deployment flexibility across diverse physical infrastructure configurations. Pure sine wave output on battery ensures compatibility with active PFC power supplies common in modern servers, network switches, and storage appliances.

Integrated LCD status display provides at-a-glance visibility into load percentage, estimated runtime, battery charge level, and input/output voltage without requiring a connected management session. The UPS supports USB and serial connectivity for integration with APC PowerChute software, enabling graceful OS shutdown sequencing, event logging, and scheduled self-tests. A built-in user-replaceable battery design and hot-swap capability reduce planned maintenance windows, making the BR1500MS2 well suited for IT teams managing distributed sites with limited on-site technical staffing.

Ideal for

• Protecting rack-mounted network switches, routers, and firewalls in branch office and retail network closets during utility outages or voltage instability
• Providing battery backup and AVR for edge computing nodes and IoT gateway appliances deployed in environmentally variable locations outside of a primary data center
• Supporting graceful shutdown of small rack servers and NAS devices in remote or unattended sites via PowerChute software integration over USB
• Conditioning power for VoIP telephony systems and unified communications equipment sensitive to voltage fluctuations and brief interruptions
• Supplying regulated, sine wave output for servers equipped with active PFC power supplies in satellite offices where utility power quality is inconsistent
• Serving as a compact 1U rack power backup solution in point-of-sale back-office environments where rack space is limited and continuous uptime is operationally critical
