Vertiv PB-GXT34-1500VA 1500VA Online UPS Power Buffer
Overview
The Vertiv PB-GXT34-1500VA is a 1500VA / 1350W power buffer unit from the GXT34 product line, designed to condition and protect 120V AC loads in commercial installations. With a TAA-compliant listing, it is eligible for federal procurement and government projects where the Trade Agreements Act applies. The unit operates on a standard L-N-G 120V circuit — no specialty wiring or step-down transformer required in North American installations, which simplifies deployment in server rooms, network closets, and security equipment racks.
At 1500VA / 1350W, this unit can sustain meaningful loads across commercial UPS and power conditioning applications. The 1350W real-power rating (0.9 power factor) is the number that matters for capacity planning — VA ratings alone can overstate usable capacity on loads with poor power factor. Vertiv's GXT34 series is part of a broader Vertiv power and infrastructure line that spans rack PDUs, UPS systems, and thermal management. For buyers evaluating runtime and battery architecture, consult the full UPS selection guide alongside the manufacturer datasheet for this SKU, as runtime curves, outlet configuration, and transfer time are not confirmed in available evidence and should not be assumed.
Key Features
- 1500VA / 1350W Capacity: Sized for edge racks, network closets, or security equipment rows — enough headroom to carry a modest NVR, PoE switch, and associated gear through brief outages without load-shedding.
- 120V Input and Output (L-N-G): Connects directly to standard North American branch circuits with no transformer, reducing installation complexity and minimizing potential points of failure.
- TAA Compliant: Meets Trade Agreements Act requirements — eligible for GSA schedules and federal/state procurement vehicles where country-of-origin compliance is mandatory. Verify against the current TAA product list at time of purchase.
Integration and Compatibility
The PB-GXT34-1500VA is part of Vertiv's GXT34 platform. For deployments requiring runtime extension, compatibility with external battery modules or matching rack accessories should be confirmed against the manufacturer's compatibility matrix. This unit is sourced factory-new with no grey-market or parallel import exposure.
Frequently Asked Questions
Q: Is the PB-GXT34-1500VA TAA compliant?
A: Yes, the PB-GXT34-1500VA carries a TAA Compliant listing, making it eligible for federal and government procurement under GSA schedules. Verify compliance status against the current TAA-designated products list at time of purchase.
Q: What is the real-power (watt) rating of the PB-GXT34-1500VA?
A: The PB-GXT34-1500VA is rated at 1350W (1500VA). Use the 1350W figure for capacity planning — it reflects the actual real power the unit can sustain, which matters more than the VA rating when sizing for resistive or mixed loads.
Q: What input voltage does the PB-GXT34-1500VA require?
A: The unit operates on 120V AC input with standard L-N-G wiring, compatible with North American branch circuits. No step-down transformer or specialty outlet is required.
Q: Can the PB-GXT34-1500VA be used on government or federal projects?
A: Yes. The TAA Compliant designation makes this unit eligible for federal procurement and government contracts subject to the Trade Agreements Act. Confirm eligibility with your contracting officer at time of award.
The PB-GXT34-1500VA sits at a practical capacity point for mid-density security and network edge racks — 1350W of real power (1500VA) on a standard 120V L-N-G circuit is enough to carry a core NVR, managed PoE switch, and access control panel through a brief outage without load-shedding. I recommend it when TAA compliance is a hard procurement requirement and you're working in the 1kW–1.3kW load band.
Technical Highlights:
- 1350W Real Power Rating: The watt figure, not the VA, is what you size against — 1350W at 0.9 power factor means you're not losing usable capacity to a low-PF load mix, which is the common trap when buyers size purely on VA.
- 120V / L-N-G Input: Drops onto any standard North American branch circuit — no dedicated outlet type, no transformer, no re-wiring. That keeps installation straightforward in retrofit scenarios where pulling new circuits is not an option.
- TAA Compliant Listing: A hard gate for federal, state, and DoD-adjacent contracts. If your procurement vehicle mandates TAA, this unit clears it — budget the time to verify against the active product list at time of purchase, as TAA designations can change between catalog cycles.
Deployment Considerations:
- Before committing to this unit, confirm outlet count, form factor (tower vs. rack), battery runtime curves, and transfer time from the manufacturer datasheet — these specs are load-bearing for any serious sizing exercise and are not confirmed in available evidence here.
- If this unit is replacing an existing GXT34 in a runtime-extended configuration, verify external battery module compatibility with Vertiv directly — the GXT34 platform has multiple battery expansion options and not all are cross-compatible across revision levels.
The PB-GXT34-1500VA is well-positioned for TAA-gated government facility edge closets and small security equipment rooms running NVR-plus-switch loads in the 1kW range — it is not the right pick for high-density compute or multi-rack UPS consolidation, where a 3-phase or higher-kVA unit is more appropriate.
