APC by Schneider Electric SRT5KRMTF vs Vertiv GXT5-5000MVRT4UXLN: Specification Comparison
Both the APC Smart-UPS SRT5KRMTF and the Vertiv GXT5-5000MVRT4UXLN are 5 kVA rack-mount uninterruptible power supplies targeting data-center, server-room, and critical-infrastructure deployments. The APC unit is a step-down transformer accessory designed to convert 208 V input to 120 V output for downstream NEMA 5-20R loads, while the Vertiv is a full online double-conversion UPS supporting both 208 V and 120 V output configurations. Buyers evaluating true UPS runtime protection alongside voltage conversion and outlet density will find meaningful tradeoffs across topology, wiring, management depth, and physical footprint.

Which unit delivers more robust power conditioning and what are the real power ratings?
The SRT5KRMTF is rated at 5,000 VA but its specs do not list a watt (W) rating or a power factor, so true watt capacity cannot be confirmed from the provided data. It functions as a step-down transformer accessory — it converts 208 V input (NEMA L6-30P, 30 A circuit) to 120 V output across 12 NEMA 5-20R receptacles at up to 24 A maximum line current. Its topology (online, line-interactive, or standby) is not stated in the provided specifications.
The Vertiv GXT5-5000MVRT4UXLN is explicitly rated 5,000 VA and 5,000 W (unity power factor) and uses an on-line double-conversion topology, which regenerates a clean sine wave on every cycle regardless of input quality. Output is user-configurable between 208 V and 120 V. Input accepts a typical 208 VAC with a range of 176–280 VAC. Efficiency reaches up to 98% in Active ECO Mode and up to 95% in standard on-line mode, per Vertiv's spec sheet. Wiring is hardwired in and out, with optional Power Output Distribution (POD) modules available.
For buyers who need a confirmed watt rating, unity power factor, or a specific UPS topology guarantee, the Vertiv spec sheet provides that data; the APC spec sheet does not.
How do the two units differ in outlet configuration, wiring, and remote management capabilities?
The SRT5KRMTF provides 12 NEMA 5-20R receptacles (20 A, 120 V) on its output side — a meaningful outlet count for dense 1U server or network gear populations. Input is via a single NEMA L6-30P plug (hardwired to a 30 A circuit). No management interface, network card, or protocol support is listed in the provided specifications for this unit.
The Vertiv GXT5-5000MVRT4UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/Webcard and supports USB, RS485, RS232, a terminal block, and an external battery connector. SNMP and web management are enabled out of the box. A serial connection provides out-of-band management. The control panel is a full-color graphic LCD with gravity-sensing orientation. The output receptacle type and count are not listed in the provided specifications — buyers requiring specific outlet counts or NEMA receptacle types must verify with Vertiv documentation.
For managed environments requiring SNMP polling, web dashboards, or integration with DCIM platforms, the Vertiv arrives network-ready at no additional card cost. The APC unit lists no management capability in the provided specs.
How do the two units compare on physical footprint, weight, and operating environment ratings?
The SRT5KRMTF occupies 2U of rack space and weighs 95.0 lb (43.09 kg). Its height dimension is listed as 3.50 in (8.9 cm), consistent with 2U. Width and depth are not provided in the supplied specifications. Operating humidity is rated 0–95% non-condensing; operating altitude up to 10,000 ft. Operating temperature is not stated for operating conditions — only storage temperature (5–113 °F / -15–45 °C) is listed.
The Vertiv GXT5-5000MVRT4UXLN occupies a flexible rack/tower form factor and lists physical dimensions of 6.8 in H × 16.9 in W × 25.6 in D, weighing 125.6 lb — 30.6 lb heavier than the APC. Operating temperature is explicitly rated +32 to +104 °F (0–40 °C). Humidity and altitude ratings are not provided in the supplied specifications. The unit carries ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications.
The APC unit is lighter and confirmed 2U; the Vertiv is heavier and larger but provides explicit operating temperature data and multiple safety certifications that the APC spec sheet does not list.
Which should you choose: the SRT5KRMTF or the GXT5-5000MVRT4UXLN?
Our take: The GXT5-5000MVRT4UXLN is the stronger choice when a buyer needs a fully self-contained, network-managed online double-conversion UPS with a confirmed 5,000 W (unity power factor) rating and factory-included SNMP management. The Vertiv delivers a rated 5,000 W versus an unconfirmed watt figure for the APC, supports up to 98% efficiency in ECO mode versus no efficiency figure stated for the APC, and ships with a pre-installed RDU101 SNMP/Webcard while the APC lists no management interface at all. The SRT5KRMTF is the appropriate selection when an existing 208 V UPS or PDU is already in the rack and the installer simply needs step-down voltage conversion with 12 discrete NEMA 5-20R 120 V outlets — it is 30.6 lb lighter and consumes only 2U. Buyers should note the APC unit's operating temperature spec is absent from provided data, while the Vertiv is explicitly rated to 40 °C.

Frequently Asked Questions
Which should you choose: the SRT5KRMTF or the GXT5-5000MVRT4UXLN?
The GXT5-5000MVRT4UXLN is the stronger choice when a buyer needs a fully self-contained, network-managed online double-conversion UPS with a confirmed 5,000 W (unity power factor) rating and factory-included SNMP management. The Vertiv delivers a rated 5,000 W versus an unconfirmed watt figure for the APC, supports up to 98% efficiency in ECO mode versus no efficiency figure stated for the APC, and ships with a pre-installed RDU101 SNMP/Webcard while the APC lists no management interface at all. The SRT5KRMTF is the appropriate selection when an existing 208 V UPS or PDU is already in the rack and the installer simply needs step-down voltage conversion with 12 discrete NEMA 5-20R 120 V outlets — it is 30.6 lb lighter and consumes only 2U. Buyers should note the APC unit's operating temperature spec is absent from provided data, while the Vertiv is explicitly rated to 40 °C.
Can I use the SRT5KRMTF as a standalone UPS, or do I need a separate battery backup?
Based on the provided specifications, the SRT5KRMTF is described as a step-down transformer — its specs list no battery, no runtime, and no UPS topology (online, line-interactive, or standby). It converts 208 V input to 120 V output across 12 NEMA 5-20R outlets but does not appear to provide battery backup on its own. Buyers requiring runtime protection should pair it with a compatible upstream UPS or evaluate the Vertiv GXT5-5000MVRT4UXLN, which is an explicit on-line double-conversion UPS.
Is the GXT5-5000MVRT4UXLN compatible with standard SNMP monitoring software out of the box?
Yes, per the provided specifications. The Vertiv GXT5-5000MVRT4UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/Webcard with SNMP and web management enabled. It also supports USB, RS485, RS232, and a terminal block interface. Serial out-of-band management is supported. No additional card purchase is listed as required to enable SNMP. The SRT5KRMTF lists no management interface in its provided specifications.
Which unit is better suited for a high-density 120 V server rack fed from a 208 V building circuit?
The SRT5KRMTF is purpose-built for this scenario: it accepts a single NEMA L6-30P 208 V input (30 A circuit, 24 A max line current) and distributes 120 V across 12 NEMA 5-20R outlets — directly serving high-density 120 V 1U servers. The Vertiv GXT5-5000MVRT4UXLN supports user-configurable 208 V or 120 V output but uses hardwired input and output connections; its outlet type and count are not listed in the provided specifications. If discrete NEMA 5-20R receptacle count is the primary requirement, the SRT5KRMTF's spec sheet confirms 12 outlets while the Vertiv's does not.
