Model specifications & service record

SubcategoryLine-interactive UPS
Topology / functionLine-interactive UPS with automatic voltage regulation (AVR); mains power is normally passed through the AVR path, with inverter transfer on outage/out-of-range supply.
VA and W ratings / outlets1550 VA / 1100 W; 230 V IEC version. Manufacturer documentation identifies eight IEC C13 and one IEC C19 output receptacle on the 5P1550i configuration.
Battery / replacementSealed lead-acid battery pack, replaceable under Eaton’s service instructions; battery packs are model-specific. Do not assume hot-swap compatibility across every 5P suffix.
Runtime / operating conditionsEaton’s 5P model runtime curves depend on actual watt load and battery condition. Consult the 5P1550i curve for the connected load; quoted time is an estimate, not a guaranteed hold-up interval.
Interfaces / monitoringLCD, USB and RS-232 communication; optional communication slot/accessories depend on 5P revision. Confirm software and cable support before relying on automatic host shutdown.
Electrical safety / limits230 V regional device; IEC C13 and C19 load current limits apply. Maintain ventilation and avoid exceeding 1100 W. Battery replacement, disposal, and service must follow the model’s manual; line-interactive AVR does not make this a double-conversion UPS.
Revision / variant identificationUse exact 5P1550i product code and region. 5P1550, 5P1550R, 5P1550iR and other suffixes have different connectors, orientation, or regional input/output arrangements; do not transpose outlet counts.

Service & archival notes

  • Record nameplate and battery labels before removal; separate measured behavior from manufacturer ratings and record load, input conditions, temperature and test date.
  • Do not open an energized unit. Mains equipment and batteries can retain hazardous energy; have battery installation, disposal, and electrical work performed according to the product manual and local rules.
  • For archival units, document missing covers, damaged cords, alarms, failed indicators, battery age/swelling/leakage, and any substituted part. Do not return a damaged unit to service.
  • Product and manual links below are the primary reference for the named regional model. Verify exact revisions rather than transferring ratings from a similarly named SKU.
