Banking

Banking environments need UPS coverage at two scales: per-branch (ATMs, teller stations, point-of-sale, PIN pads, CCTV, branch networking) and at back-office or core-banking (servers, transaction databases, network gear). The Standby Systems banking taxonomy page lists Pure Line LI, Sentinel Pro, Sentinel Rack, and Pure Line (tower and rack variants) as the recommended set — covering the entry-level line-interactive AVR-driven Pure Line LI through to online double-conversion Pure Line and Sentinel-class units for higher-criticality loads.

Inferred from the product mix: most branch and ATM-class loads in the 0.65–3 kVA window can be served by line-interactive units, while servers handling transactions or hosting branch automation deserve online double-conversion. None of this is stated explicitly on the page; the inference is from sizing and topology of the products surfaced.

What to size for

  • Per-branch: total of teller stations + ATMs + CCTV + networking (typical 1–3 kVA at small branch, more at larger)
  • Runtime: usually short, sized to bridge to a generator or for graceful shutdown
  • Transaction-data integrity is the failure mode that matters more than continuous uptime
  • Diverse load mix (electronics, motors in CCTV pan/tilt, electronic locks) means sine-wave output is preferable
  • Pure Line LI — entry-level line-interactive with Buck/Boost AVR; sized for ATM/PoS-class loads
  • Sentinel Pro — online double-conversion for higher-criticality branch loads up to 3 kVA
  • Sentinel Rack — rack-mount sibling of Sentinel Pro, 1.5 / 3 kVA
  • Pure Line — online double-conversion tower/rack, 1–10 kVA, suitable for branch back-office racks
