How do the SRT5KXLT-IEC and GXT5LI-5KL630RT3UXLN compare on real power output, input flexibility, and waveform quality?
The SRT5KXLT-IEC is rated at 5000 VA / 4250 W, yielding a power factor of 0.85. The GXT5LI-5KL630RT3UXLN is rated at 5000 VA / 4900 W, yielding a higher power factor of 0.98. For watt-dense loads such as high-density compute or GPU servers, the Vertiv unit delivers 650 W more usable real power from the same VA rating.
On input voltage flexibility, the APC unit accepts 100–275 V, accommodating a wider range of feed voltages including 100 V and 120 V single-phase feeds. The Vertiv unit accepts 200–240 V input only, requiring a dedicated 208 V or 240 V feed. The APC unit's input frequency range is 40–70 Hz versus Vertiv's range, which is not specified in the provided specs.
Both units produce a sine-wave output. The APC unit specifies output voltage THD of 2% and a crest factor of 3:1. Neither THD nor crest factor is provided in the Vertiv specs. The APC unit also specifies a surge energy rating of 480 J; no surge energy rating is provided for the Vertiv unit.
How do the two units compare on physical footprint, weight, battery technology, and operating environment?
Physical dimensions are provided only for the Vertiv GXT5LI-5KL630RT3UXLN: 5.25 in H × 16.9 in W × 35 in D (3U rack), weighing 103 lbs. No weight or dimensional data is provided in the APC SRT5KXLT-IEC specs as supplied, preventing a direct size or weight comparison.
Battery chemistry is a key differentiator. The Vertiv model's SKU and product name explicitly identify it as a Lithium-ion UPS. The APC SRT5KXLT-IEC specs as provided do not specify battery chemistry; buyers should consult APC's full datasheet to confirm whether VRLA or Li-ion is standard or optional for this SKU.
Operating temperature is provided only for the Vertiv unit: 32°F to 104°F (0°C to 40°C), with a 10% derating noted at 50°C. No operating temperature range is provided in the APC specs as supplied. Noise level is specified only for the APC unit at 55 dB; no acoustic data is provided for the Vertiv unit.
Which unit offers broader management capabilities, certifications, and connectivity for enterprise or monitored environments?
The APC SRT5KXLT-IEC specifies web-based management, auto-restart, Emergency Power Off (EPO), and audible alarms. These are confirmed capabilities in the provided specs. No management interface, EPO capability, or alarm specifications are listed in the Vertiv GXT5LI-5KL630RT3UXLN specs as provided; buyers should verify Vertiv's management card options separately.
The Vertiv GXT5LI-5KL630RT3UXLN carries a defined list of agency approvals: IEC 62040-1:2008+A1 2013, IEC 62619 1st Ed., IEC 62040-2 2nd Ed., IEC 61000-3-2, IEC 61000-3-12, CISPR 22 Class A, FCC Part 15 Class A, and UL 1778. No agency approvals or certifications are listed in the APC SRT5KXLT-IEC specs as provided.
The Vertiv unit's input connector is specified as an L6-30P twist-lock plug, which constrains the installation to circuits with matching receptacles. The APC unit's model designation includes 'IEC,' indicating IEC-format outlets on the output side; input connector type is not specified in the provided APC specs. Buyers integrating into existing panel or PDU infrastructure should verify connector compatibility for both units before specifying.
Which should you choose: the SRT5KXLT-IEC or the GXT5LI-5KL630RT3UXLN?
Our take: The GXT5LI-5KL630RT3UXLN is the stronger choice when maximizing real power delivery and battery longevity matter most, while the SRT5KXLT-IEC is the stronger choice when broad input voltage flexibility and confirmed web management are required. Three concrete spec deltas: first, the Vertiv delivers 4900 W versus the APC's 4250 W — a 650 W advantage at identical VA that is decisive for watt-dense compute loads. Second, the APC accepts 100–275 V input, making it deployable on 120 V feeds and international supplies; the Vertiv is limited to 200–240 V. Third, the Vertiv carries explicit Li-ion certification (IEC 62619) and a documented compliance list including UL 1778; the APC's certifications are absent from the provided specs. For data centers requiring maximum real-power headroom and Li-ion runtime benefits, specify the Vertiv. For mixed-voltage environments or installations where EPO and native web management are confirmed requirements, the APC is the documented choice.

Which unit supports a wider range of input voltages — the SRT5KXLT-IEC or the GXT5LI-5KL630RT3UXLN?
The APC SRT5KXLT-IEC supports a broader input voltage range of 100–275 V, making it usable on 120 V single-phase circuits and a wider range of international feeds. The Vertiv GXT5LI-5KL630RT3UXLN is specified for 200–240 V input only, requiring a dedicated 208 V or higher feed.
Does the GXT5LI-5KL630RT3UXLN actually deliver more usable power than the SRT5KXLT-IEC despite both being 5000 VA?
Yes. The Vertiv GXT5LI-5KL630RT3UXLN is rated at 4900 W (0.98 power factor), while the APC SRT5KXLT-IEC is rated at 4250 W (0.85 power factor). For watt-dense server or GPU loads that approach the full wattage rating, the Vertiv provides 650 W more usable real power from the same VA class.
