APC by Schneider Electric SUVTP15KF2B4S vs Vertiv GXT5-15KMVRT11UXLN: Specification Comparison
Both the APC Smart-UPS VT SUVTP15KF2B4S and the Vertiv Liebert GXT5 GXT5-15KMVRT11UXLN are 15 kVA rackmount uninterruptible power supplies designed for data center and critical infrastructure applications. Each employs an on-line double-conversion topology, placing them squarely in the same purchase category for buyers protecting server rooms, network closets, or edge computing environments. This comparison examines power and efficiency, physical and environmental characteristics, and management and connectivity—the three dimensions that most often determine which unit fits a specific deployment.

Which UPS delivers more usable power and better efficiency?
Both units are rated at 15 kVA, but they diverge immediately on watt output. The SUVTP15KF2B4S is rated at 12,000 W (0.80 power factor), while the GXT5-15KMVRT11UXLN is rated at 15,000 W (1.00 power factor). For loads demanding the full kilowatt capacity of a 15 kVA frame, the Vertiv unit offers 25% more real-power headroom.
Efficiency separates the two models further. APC specifies 93% efficiency for the SUVTP15KF2B4S with no operating-mode qualifier. Vertiv specifies up to 95% in on-line double-conversion mode and up to 98% in Active ECO mode for the GXT5-15KMVRT11UXLN. The ECO-mode figure is conditional on load profile and bypass engagement, but even the on-line mode figure of 95% exceeds APC's stated 93%. The GXT5-15KMVRT11UXLN also carries ENERGY STAR 2.0 certification; no equivalent certification is listed for the SUVTP15KF2B4S.
Output voltage differs as well. The SUVTP15KF2B4S is specified at 208 V output. The GXT5-15KMVRT11UXLN supports 208/120 VAC, described as user-configurable, accommodating mixed-voltage loads from a single unit without additional step-down transformers. Input voltage range is not specified for the SUVTP15KF2B4S; the GXT5-15KMVRT11UXLN accepts 176–280 VAC.
How do the two units compare on physical footprint and environmental ratings?
Physical dimensions are provided only for the GXT5-15KMVRT11UXLN: 19.0 in (H) × 16.9 in (W) × 26.7 in (D), weighing 396.6 lbs. No height, width, depth, or weight data is listed in the provided specifications for the SUVTP15KF2B4S; buyers will need to consult APC's datasheet for rack-unit count and clearance planning.
Operating temperature is identical for both: 0–40 °C (32–104 °F). The SUVTP15KF2B4S additionally specifies an operating relative humidity range of 0–95% and an operating altitude ceiling of 999.9 m, with a non-operating altitude limit of 15,000 m. No humidity or altitude figures are listed for the GXT5-15KMVRT11UXLN in the provided specifications.
The SUVTP15KF2B4S includes storage temperature data (–50 to 40 °C) and storage humidity (0–95%), useful for warehousing and staging scenarios. The GXT5-15KMVRT11UXLN's wiring is hardwired in and out with optional PODs; the SUVTP15KF2B4S lists one AC outlet in the provided specs. Battery technology for the SUVTP15KF2B4S is specified as Sealed Lead Acid (VRLA); battery chemistry is not stated for the GXT5-15KMVRT11UXLN in the provided specifications.
Which unit offers more management and integration options?
The GXT5-15KMVRT11UXLN ships with a factory pre-installed Vertiv Liebert IntelliSlot RDU120 SNMP/Webcard, enabling SNMP and web management out of the box. Additional interfaces include USB, RS-485, RS-232, a terminal block, and an external battery connector. Protocols documented include SNMP and web management for remote monitoring, plus serial for out-of-band management. A full-color graphic LCD with gravity-sensing orientation is included for local status and configuration.
The SUVTP15KF2B4S lists one serial port in the provided specifications and includes an audible alarm and an Emergency Power Off (EPO) input. No SNMP card, web interface, USB port, or LCD display is mentioned in the provided specifications. Buyers requiring network-based UPS monitoring would need to verify whether an optional management card is available and factor in that additional cost and configuration step.
Output THD for the SUVTP15KF2B4S is specified at ≤5%. No output THD figure is listed for the GXT5-15KMVRT11UXLN in the provided specifications. The GXT5-15KMVRT11UXLN carries UL 1778, c-UL, RoHS2, and REACH listings; compliance certifications are not listed for the SUVTP15KF2B4S in the provided specifications. Battery recharge time for the SUVTP15KF2B4S is stated as 5 hours; no recharge time is listed for the GXT5-15KMVRT11UXLN.
Which should you choose: the SUVTP15KF2B4S or the GXT5-15KMVRT11UXLN?
Our take: The GXT5-15KMVRT11UXLN is the stronger choice when maximum real-power delivery, higher efficiency, and out-of-the-box network management are the primary requirements. Concretely: it delivers 15,000 W versus 12,000 W—a 25% real-power advantage at the same 15 kVA rating—achieves up to 95% on-line efficiency versus APC's stated 93%, and ships with a factory-installed SNMP/web card while the SUVTP15KF2B4S lists only a serial port in the provided specifications. The SUVTP15KF2B4S holds an advantage where altitude tolerance, storage temperature range, and output THD documentation matter; it also specifies an EPO input and a 5-hour battery recharge time, neither of which is confirmed for the Vertiv unit in available specs. Buyers on APC-standardized infrastructure or requiring an EPO circuit should verify SUVTP15KF2B4S management options separately before ruling it out.
