[ LINE-INTERACTIVE UPS // IDENTIFIED MODEL ]
Vertiv Liebert PSA5-1000MT120
Vertiv line-interactive AVR UPS, rated 1000 VA / 600 W. This record describes the identified regional model only. Check the complete nameplate, hardware revision and matching manufacturer documentation before installation or load selection.
ARCHIVAL IDENTIFICATION: Record complete SKU/suffix, input/output labels, serial/date code, hardware revision, battery type/age, accessories, test conditions and manual revision. Similar model names do not establish electrical equivalence.
Exact model specifications
| Manufacturer / exact model | Vertiv Liebert PSA5-1000MT120 (North American model record; verify complete SKU, revision and serial/date label). |
|---|---|
| Topology | Line-interactive UPS with automatic voltage regulation (AVR); supported input fluctuations may be corrected without battery transfer. This is not a standby-only or online double-conversion unit. |
| Capacity / input | 1000 VA / 600 W; 120 V AC North American model; confirm the exact MT120 label and nominal 60 Hz supply. VA and W are separate limits; stay under both. |
| AC output / waveform | 120 V AC nominal; simulated sine-wave output while on battery. PSA5 is line-interactive, with AVR handling supported input variations. |
| Outlets / load assignment | Ten NEMA 5-15R: five battery-backup + surge-protected and five surge-only on the MT120 configuration. Check physical outlet labels. |
| Battery chemistry / service | Internal user-replaceable VRLA sealed lead-acid battery; follow PSA5 safe replacement procedure and dispose/recycle according to local rules. |
| Runtime / test conditions | Vertiv’s PSA5 guide provides model-specific runtime tables. The 1000 VA unit is rated 600 W; use its table for the measured load rather than treating the VA/W limit as an expected runtime. Runtime tests should record connected watts, charge state, battery age/health, temperature and test date. |
| Host signaling / software | USB host communication and Vertiv Power Assist monitoring/shutdown software. Check Vertiv’s current Power Assist host-OS requirements and model support before relying on automatic shutdown. |
| Load compatibility | 120 V loads within 1000 VA / 600 W and manufacturer-listed outlet assignments. Verify load startup/inrush, waveform requirements and grounding; charging USB ports are not host data ports. |
Safety, service & limits
- Use only with the grounded voltage/frequency and environment allowed by the complete unit label and current model manual. Never defeat grounding or daisy-chain UPS outputs.
- Do not connect heaters, laser printers, motors or other high-inrush loads unless the manufacturer expressly permits them and their steady-state and startup demand remain within the UPS limits.
- Do not open an energized UPS or work on battery terminals. Sealed lead-acid batteries can deliver destructive fault current; avoid short circuits, damaged/swollen/leaking cells and unapproved replacements. Follow the manufacturer isolation, service and recycling directions.
- Remove damaged equipment from service if the case, cord, plug, grounding, outlet, battery or indicator shows heat, swelling, leakage, cracking, odor, corrosion or other fault. Follow the maker’s safe shutdown guidance.
- Keep ventilation clear, protect the unit from liquid and excessive heat, and test host shutdown and runtime under a controlled load. Battery backup is finite and is not a substitute for code-compliant wiring or an independent data backup.
