P80g 208–240V line-interactive rack UPS
The P80g is a 208–240 V pure sine wave line-interactive rack/tower UPS for distributed infrastructure where efficient power protection is required without the complexity of online double-conversion. Automatic Voltage Regulation (AVR) stabilizes input voltage while up to 99% ECO-mode efficiency lowers operating cost — delivering up to 5 kVA with internal batteries in a 2U package, with IEC-based output. For 120 V, see the P80; for online, the P91g.
Efficient 208–240V rack protection
The P80g is designed for environments where utility power is generally stable but outages and voltage fluctuations still occur. Line-interactive topology provides voltage regulation through AVR without continuous double-conversion — improving efficiency while maintaining reliable battery backup during outages (typical 2–6 ms transfer). With up to 5 kVA of internal-battery capacity in a 2U chassis and IEC-based output aligned with rack PDUs, it is well suited to distributed deployments prioritizing efficiency, simplicity, and cost control.
What the P80g delivers
Automatic Voltage Regulation corrects under-/over-voltage (162–290 VAC input range) without draining the battery.
Clean network-grade sine wave with IEC C19/C13 output aligned to rack PDU architecture; 208/120 or 240/120 split output on 5 kVA models.
High-efficiency ECO mode (99%) and 95% buck/boost reduce energy use and heat at all load levels.
Hot-swappable batteries simplify service; temperature-compensated charging prolongs battery life and reduces replacement cost.
Shed less-critical loads to maximize uptime for priority equipment; a smart LCD shows precise status from the front panel.
An optional XBDM bypass module allows the P80g-3000 to be serviced without dropping the load; auto-restart resumes after a full discharge.
The 208–240V line-interactive tier
The P80g operates as the high-capacity line-interactive UPS platform for 208–240 V distributed infrastructure — deployed across IDF/MDF closets, telecom racks, enterprise IT, and AV systems, and standardized across multiple sites. It is the 208–240 V counterpart to the 120 V P80 within the Xtreme Power architecture.
Line-interactive or online?
Compared to online UPS platforms such as the P91g, the P80g is designed for applications where full-time conditioning isn’t required — offering higher operating efficiency, lower complexity, and reduced cost while still providing battery backup and voltage regulation. Online systems are selected when zero transfer time or continuous conditioning is required for sensitive loads or unstable utility environments.
Replace legacy 208–240V line-interactive UPS
The P80g is commonly deployed as a replacement for line-interactive rack UPS platforms — APC Smart-UPS (208–240V), Eaton 5P and 9PX, and Vertiv Liebert PSI — providing a standardized platform for distributed infrastructure with consistent deployment, simplified maintenance, and predictable lifecycle management.
Three models, 3–5 kVA
| Model | Capacity | Form factor | Output | Dimensions (W×D×H) | Weight | Receptacles |
|---|---|---|---|---|---|---|
| P80g-3000 | 3000 VA / 2700 W | 2U | 208/220/230/240 V | 17.2 × 23.6 × 3.5 in | 61.9 lb | (1) C19 + (8) C13 |
| P80g-5000 | 5000 VA / 4500 W | 2U | 208/120 or 240/120 V | 17.2 × 23.6 × 3.5 in | 78.5 lb | (1) L6-30R + (4) C19 |
| P80g-5KTB | 5000 VA / 4500 W | 4U (5000 + transformer) | 208/120 or 240/120 V | 17.2 × 23.6 × 7.0 in | 224 lb | (2) L6-30R + (2) L6-20R + (12) 5-15/20R |
Pure sine wave output; input range 162–290 VAC. Optional receptacle configurations: L6-30R, L6-20R, L6-15R, 6-15/20R. The P80g-5KTB bundles the P80g-5000 (2U) with a 2U isolation transformer (4U total) for split 208/120 or 240/120 V output.
P80g-5KTB — the only isolated line-interactive UPS in the range
The P80g-5KTB is the P80g-5000 bundled at the factory with a 2U isolation transformer: 4 U total, 224 lb, giving split 208/120 or 240/120 V output. Everything else isolated in the Xtreme Power line is online double-conversion. This is the one place you can get galvanic isolation without paying for continuous conversion.
That matters when the site has a 208–240 V feed, needs 120 V outlets, and has a load that is sensitive to common mode noise — but does not need zero transfer time. Retail back-of-house, AV racks, and light industrial control are the usual cases.
When to choose something else. If the load cannot tolerate a 2–6 ms transfer, or the site runs from a generator, step up to online double-conversion — the TX91 covers 3.8–10 kVA with isolation integrated. If you want to size the transformer separately from the UPS, or add isolation to a P80g already installed, use a plain P80g-5000 with an XPD-IT isolation PDU downstream. Sizing and wiring for that route is on the UPS with isolation transformer page.
Whichever route, connect the sensitive equipment directly to the transformer output. Isolation is established there and nowhere else, so a power strip after it gives back most of the benefit.
Runtime at full load
Approximate full-load (100%) runtime in minutes, with internal batteries and with optional external battery packs:
| Model | Internal | +1 pack | +2 packs |
|---|---|---|---|
| P80g-3000 | 3 | 20 | 38 |
| P80g-5000 | 2 | 14 | 27 |
| P80g-5KTB | 2 | 14 | 27 |
Full-load minutes; lighter loads yield substantially longer runtimes (e.g. the P80g-3000 with two packs reaches about 66 min at 50% and about 107 min at 25% load). Up to two external battery packs are supported. Size it with the UPS selector →
Optional external battery packs
| Battery pack | For model | Dimensions (W×D×H) | Weight | Battery |
|---|---|---|---|---|
| P90-BP72 | P80g-3000 | 17.2 × 23.6 × 3.5 in | 104.4 lb | (12) 12V 9Ah / 72V |
| P80-BP72X | P80g-5000 | 17.2 × 23.6 × 3.5 in | 110.4 lb | (12) 12V 580W at 5 min / 72V |
Hot-swappable; up to two packs per supported UPS.
IEC output and standardized deployment
The P80g’s IEC-based output (C19/C13 on the 3000) aligns with IEC rack PDU architecture, supporting consistent installation across multiple sites and rack-level power distribution strategies used in enterprise and telecommunications environments. This standardized outlet design simplifies procurement and deployment across distributed infrastructure.
Built for distributed 208–240V infrastructure
The P80g is deployed across IDF/MDF environments, telecommunications racks, enterprise IT infrastructure, AV systems, and distributed technology environments — particularly well suited to multi-site deployments requiring a consistent 208–240 V rack UPS platform.

P80g — frequently asked questions
What is the difference between the P80g-5000 and the P80g-5KTB?
The 5KTB is the P80g-5000 bundled at the factory with a 2U isolation transformer, 4U total and 224 lb against 78.5 lb. Both give split 208/120 or 240/120 V output. The transformer adds galvanic separation, which is what addresses common mode noise. Choose the 5KTB when the load is sensitive to ground-referenced interference; choose the plain 5000 when you only need the voltage split.
Is the transformer in the 5KTB an isolation transformer or an autotransformer?
A true isolation transformer, with separate primary and secondary windings and no electrical path between them. An autotransformer shares a single winding, changes voltage perfectly well, and provides no galvanic separation at all. The 145 lb weight difference between the 5KTB and the plain 5000 is the giveaway: isolation transformers are heavy because the windings are separate.
Line-interactive or online at this size?
Line-interactive covers five of the ten common power problems and online double-conversion covers nine. The P80g corrects voltage using transformer taps without drawing on the battery, at a transfer time of 2 to 6 ms. Step up to online when the load cannot tolerate that transfer, when the site runs from a generator, or when noise and harmonics are the complaint rather than voltage level.
What voltages does it accept and deliver?
Input range is 162 to 290 VAC. The 3000 outputs 208/220/230/240 V. The 5000 and 5KTB output split 208/120 or 240/120 V, which is what lets a 208 V rack feed 120 V equipment.
Can I extend the runtime?
Yes, with external battery packs: the P90-BP72 on the 3000 and the P80-BP72X on the 5000, up to two packs. Runtime at full load runs from a couple of minutes internally to roughly 27 minutes with two packs.
Is the P80g TAA compliant?
Yes, confirmed by the manufacturer. Note that the certification listings for this 208-240 V platform are CE and RoHS; there is no UL listing on this range.
What is the XBDM and can I use one?
A maintenance bypass and distribution module that lets the UPS be serviced or replaced without dropping the load. It is available on the P80g-3000.
Where does the P80g fit against the P80?
Voltage. The P80 is the 120 V line-interactive platform; the P80g is the 208 to 240 V equivalent for racks fed at higher voltage. Same topology, different input.
