[ LINE-INTERACTIVE UPS // IDENTIFIED MODEL ]
Vertiv Liebert PSA5-1500MT120
Vertiv line-interactive AVR UPS, rated 1500 VA / 900 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 PSA5-1500MT120 (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 | 1500 VA / 900 W; 120 V AC North American model; confirm MT120 suffix and the exact nameplate. 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 automatic voltage regulation and battery transfer when necessary. |
| Outlets / load assignment | Ten NEMA 5-15R on the MT120 version: five battery-backup + surge and five surge-only. Verify labels on the delivered hardware. |
| Battery chemistry / service | Internal user-replaceable VRLA sealed lead-acid battery; use the manual’s procedure, approved type and safe disposal/recycling route. |
| Runtime / test conditions | Use Vertiv’s PSA5 load/runtime table for this 1500 VA / 900 W model. Published values vary by exact watt load and battery state; the rated maximum is not a runtime promise. Runtime tests should record connected watts, charge state, battery age/health, temperature and test date. |
| Host signaling / software | USB data interface for Vertiv Power Assist monitoring and orderly shutdown, subject to the software’s current host-OS compatibility list. Do not confuse power/charging sockets with UPS signaling. |
| Load compatibility | 120 V equipment within both 1500 VA and 900 W limits and the model’s outlet groups. Confirm startup demand, sine-wave requirements, ventilation and grounded circuit before use. |
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.
