APC by Schneider Electric SRTL5KRMTF vs Vertiv GXT5-5000MVRT4UXLN: Specification Comparison
Both the APC SRTL5KRMTF and the Vertiv GXT5-5000MVRT4UXLN are 5 kVA online double-conversion rack-mount UPS systems targeting IT infrastructure, telecom, and security deployments where continuous clean power is mandatory. The APC unit functions as an isolation/step-down transformer module pairing with the SRTL5KRM host UPS to deliver 120 V output from a 208 V feed, while the Vertiv unit operates as a standalone 5 kVA UPS with configurable 208/120 V output. Buyers evaluating this class of product typically weigh power architecture, form-factor, input/output flexibility, management capability, and environmental tolerances.

How do the two units differ in power rating, input/output voltage architecture, and efficiency?
The APC SRTL5KRMTF is rated at 5,000 VA load capacity with a 208 V single input (NEMA L6-30P, 30 A circuit, 24 A max line current) and a fixed 120 V output via twelve NEMA 5-20R receptacles. It is specifically an isolation/step-down transformer module — it requires the companion SRTL Smart-UPS Ultra host unit to provide UPS functionality; on its own it does not supply battery backup. The input-to-output step-down is hardwired: 208 V in, 120 V out, non-configurable.
The Vertiv GXT5-5000MVRT4UXLN is a self-contained online double-conversion UPS rated at 5,000 VA / 5,000 W with a user-configurable output of 208 V or 120 V. Its input accepts a typical 208 VAC feed with a range of 176–280 VAC, and both input and output are hardwired (no receptacle block specified in the provided specs; optional PODs available). Vertiv specifies efficiency up to 98% in Active ECO Mode and up to 95% in on-line mode. No efficiency figure is provided in the APC SRTL5KRMTF specs.
How do the units compare on physical form factor, weight, and operating environment tolerances?
The APC SRTL5KRMTF occupies 2U of rack space and is described as rack-mounted horizontal with front mounting. Its stated dimension is 3.50 in (8.9 cm) height; width and depth are not provided in the supplied specs. It weighs 95.00 lb (43.09 kg). Operating altitude is specified at 0–10,000 ft. Relative humidity tolerance is 0–95% non-condensing for both operating and storage. Storage temperature is 5–113 °F (–15 to 45 °C); no operating temperature range is listed in the provided specs.
The Vertiv GXT5-5000MVRT4UXLN ships in a flexible rack/tower form factor at 6.8 in H × 16.9 in W × 25.6 in D, occupying more physical volume (rack unit count not stated in the provided specs). It weighs 125.6 lb — 30.6 lb heavier than the APC module. Operating temperature is specified at +32 to +104 °F (0 to 40 °C). No operating altitude or humidity tolerance is provided in the supplied Vertiv specs.
What management interfaces, certifications, and integration options does each unit offer?
The APC SRTL5KRMTF specs list no management interfaces, network cards, protocols, or software integration options. As a transformer module dependent on the host SRTL UPS, management capability would reside in that companion unit rather than in this module itself. No certifications or listings are cited in the provided specs.
The Vertiv GXT5-5000MVRT4UXLN comes with a factory pre-installed Vertiv RDU101 SNMP/Webcard enabling SNMP and web management out of the box. Additional interfaces include USB, RS485, RS232, a terminal block, and an external battery connector. Out-of-band management is supported via serial connection. The control panel features a full-color graphic LCD with gravity-sensing orientation for rack or tower use. Certifications listed include ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH. No equivalent certifications or management specs are provided for the APC module.
Which should you choose: the SRTL5KRMTF or the GXT5-5000MVRT4UXLN?
Our take: The GXT5-5000MVRT4UXLN is the stronger choice when a buyer needs a fully self-contained 5 kVA online UPS with built-in network management and flexible output voltage. First, the Vertiv is a complete, standalone UPS rated at 5,000 VA / 5,000 W with battery backup, whereas the APC SRTL5KRMTF is solely an isolation/step-down transformer module requiring a separate host UPS — a critical architectural difference. Second, the Vertiv ships with a factory-installed SNMP/Webcard plus USB, RS485, and RS232 interfaces; the APC module lists no management interfaces at all. Third, the Vertiv carries ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications versus no certifications listed for the APC unit. The SRTL5KRMTF is purpose-built to step down a 208 V feed to twelve NEMA 5-20R 120 V outlets when paired with an APC SRTL host UPS — making it the right selection only in that specific paired-system deployment scenario.

Frequently Asked Questions
Which should you choose: the SRTL5KRMTF or the GXT5-5000MVRT4UXLN?
The GXT5-5000MVRT4UXLN is the stronger choice when a buyer needs a fully self-contained 5 kVA online UPS with built-in network management and flexible output voltage. First, the Vertiv is a complete, standalone UPS rated at 5,000 VA / 5,000 W with battery backup, whereas the APC SRTL5KRMTF is solely an isolation/step-down transformer module requiring a separate host UPS — a critical architectural difference. Second, the Vertiv ships with a factory-installed SNMP/Webcard plus USB, RS485, and RS232 interfaces; the APC module lists no management interfaces at all. Third, the Vertiv carries ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications versus no certifications listed for the APC unit. The SRTL5KRMTF is purpose-built to step down a 208 V feed to twelve NEMA 5-20R 120 V outlets when paired with an APC SRTL host UPS — making it the right selection only in that specific paired-system deployment scenario.
Can the APC SRTL5KRMTF work as a standalone UPS like the Vertiv GXT5-5000MVRT4UXLN?
No. Based on the provided specs, the SRTL5KRMTF is described as an isolation/step-down transformer module, not a standalone UPS. It steps 208 V input down to 120 V output across twelve NEMA 5-20R outlets but does not itself supply battery backup — that function resides in a separate APC SRTL host UPS. The Vertiv GXT5-5000MVRT4UXLN is a self-contained online double-conversion UPS with its own battery system.
Which unit is better for remote monitoring in a distributed security or IT installation?
The Vertiv GXT5-5000MVRT4UXLN has a clear advantage here based on the provided specs. It includes a factory pre-installed SNMP/Webcard (Vertiv RDU101), USB, RS485, RS232, and a terminal block, enabling SNMP and web management plus out-of-band serial access out of the box. The APC SRTL5KRMTF specs list no management interfaces; any remote monitoring capability would depend on its companion SRTL host UPS, not this module.
Is the APC SRTL5KRMTF or the Vertiv GXT5-5000MVRT4UXLN lighter and easier to rack?
The APC SRTL5KRMTF is lighter at 95.00 lb (43.09 kg) versus 125.6 lb for the Vertiv GXT5-5000MVRT4UXLN — a difference of approximately 30.6 lb. The APC module is also specified at 2U rack height; the Vertiv's rack unit count is not stated in the provided specs, though its 6.8 in height suggests approximately 4U. Note that the APC module must be installed alongside its host UPS, so total system weight and rack space will be higher for the APC paired solution.
