APC by Schneider Electric SRT5KRMXLT-5KTF vs APC by Schneider Electric SRT5KRMXLT-IEC: Specification Comparison
Both the SRT5KRMXLT-5KTF and the SRT5KRMXLT-IEC are APC Smart-UPS SRT 5000VA rackmount double-conversion online UPS units — the same capacity class and topology, intended for protecting critical IT and data center loads. The key distinction is regional and infrastructure fit: the 5KTF is a 208V-input step-down transformer model delivering 120V NEMA outputs for North American mixed-voltage environments, while the IEC variant outputs 208V to IEC C13/C19 receptacles suited to international or 208V-native rack deployments. Buyers cross-shopping these are typically choosing between outlet standard and voltage architecture, not capacity.

How do output voltage, receptacle type, and load compatibility differ between the two models?
The SRT5KRMXLT-5KTF is explicitly designed as a step-down transformer model: it accepts 208V AC single-phase input and steps output down to 120V, delivering that power across 12 NEMA 5-20R, 2 NEMA L6-20R, and 2 NEMA L6-30R receptacles. This makes it the right choice for North American racks that mix 120V and 208V equipment on a single 208V feed. The rated output capacity is 5000 VA; watts output is not specified in the provided data.
The SRT5KRMXLT-IEC outputs at up to 208V with IEC C13 and C19 couplers plus IEC jumpers — the universal standard for international server and networking hardware. Its output power is specified at 4250 W (5 kVA), output frequency is 50/60 Hz, and output voltage THD is 2%. Neither watts rating nor output frequency is provided for the 5KTF in the available specifications. Buyers powering IEC-receptacle equipment in international data centers or 208V-native North American racks should use the IEC model; buyers needing 120V NEMA outlets from a 208V feed require the 5KTF.
Which model offers broader input voltage and frequency tolerance for varying power environments?
The SRT5KRMXLT-IEC specifies an input operating voltage range of 100V–275V and an input frequency range of 40–70 Hz. This wide tolerance is a meaningful advantage in international deployments, generator-backed environments, or facilities with unstable utility power, as the unit can accept a broader range of incoming power conditions before switching to battery.
The SRT5KRMXLT-5KTF lists only a single input voltage of 208V AC 1 phase; no input voltage range or input frequency range is provided in the available specifications. Buyers operating in environments where input power quality varies significantly — or where the UPS may see input outside a narrow 208V window — have documented tolerance data only for the IEC model. The 5KTF's input tolerance, if any, cannot be confirmed from the provided specs.
How do the two models compare on physical footprint, weight, network management, and warranty coverage?
The SRT5KRMXLT-5KTF occupies 5U of rack space and measures 8.58 in H × 17.01 in W × 28.31 in D (218 × 432 × 719 mm), weighing 217.99 lb (98.88 kg). This substantial weight is partly attributable to the integrated step-down transformer. Rack space and structural load-bearing capacity must be verified before installation. The 5KTF includes a 10/100 BaseT network connection for remote management. UPS warranty is 36 months; battery warranty is 24 months.
The SRT5KRMXLT-IEC does not list rack unit height, physical dimensions, or weight in the provided specifications, so a direct footprint comparison cannot be made. It confirms web-based management, audible alarms, auto-restart, and a noise level of 55 dB. Its surge energy rating matches the 5KTF at 480 J, and its crest factor is 3:1. No warranty terms are provided for the IEC model in the available specifications, making a warranty-to-warranty comparison impossible from the supplied data.
Which should you choose: the SRT5KRMXLT-5KTF or the SRT5KRMXLT-IEC?
Our take: The SRT5KRMXLT-5KTF is the stronger choice when the installation requires 120V NEMA outlets powered from a 208V feed — its integrated step-down transformer and 16 NEMA receptacles (12× 5-20R, 2× L6-20R, 2× L6-30R) serve mixed-voltage North American racks that no IEC-output UPS can address. Against that, the SRT5KRMXLT-IEC brings three documented advantages: a confirmed 4250 W real-power rating (the 5KTF's wattage is unspecified), a wide 100V–275V input tolerance versus the 5KTF's single-point 208V input spec, and IEC C13/C19 outputs for international server hardware. The 5KTF edges ahead on warranty — 36-month UPS / 24-month battery versus no warranty data available for the IEC model. Choose the 5KTF for 208V-fed, 120V-load North American deployments; choose the IEC model for international racks or 208V-native IEC equipment where input power quality may vary.

Frequently Asked Questions
Which should you choose: the SRT5KRMXLT-5KTF or the SRT5KRMXLT-IEC?
The SRT5KRMXLT-5KTF is the stronger choice when the installation requires 120V NEMA outlets powered from a 208V feed — its integrated step-down transformer and 16 NEMA receptacles (12× 5-20R, 2× L6-20R, 2× L6-30R) serve mixed-voltage North American racks that no IEC-output UPS can address. Against that, the SRT5KRMXLT-IEC brings three documented advantages: a confirmed 4250 W real-power rating (the 5KTF's wattage is unspecified), a wide 100V–275V input tolerance versus the 5KTF's single-point 208V input spec, and IEC C13/C19 outputs for international server hardware. The 5KTF edges ahead on warranty — 36-month UPS / 24-month battery versus no warranty data available for the IEC model. Choose the 5KTF for 208V-fed, 120V-load North American deployments; choose the IEC model for international racks or 208V-native IEC equipment where input power quality may vary.
Can I use the SRT5KRMXLT-IEC to power standard 120V North American servers?
No. The SRT5KRMXLT-IEC outputs at up to 208V through IEC C13 and C19 receptacles. It does not provide 120V NEMA outlets. For 120V North American loads fed from a 208V input, the SRT5KRMXLT-5KTF with its integrated step-down transformer and NEMA receptacles is the appropriate model.
Which model is better suited for international deployments or generator-backed power environments?
The SRT5KRMXLT-IEC has a documented input voltage range of 100V–275V and an input frequency range of 40–70 Hz, giving it broad tolerance for varying utility or generator power. Its IEC C13/C19 outlets are the global standard for server and network hardware. The SRT5KRMXLT-5KTF specifies only a single 208V AC input with no range data provided, so its tolerance in unstable-input environments cannot be confirmed from the available specifications.
Is the SRT5KRMXLT-5KTF or SRT5KRMXLT-IEC heavier, and does that affect rack planning?
Only the SRT5KRMXLT-5KTF provides weight data in the available specifications: 217.99 lb (98.88 kg), occupying 5U of rack space — a significant structural consideration driven by its integrated step-down transformer. No weight or rack-unit height is provided for the SRT5KRMXLT-IEC in the supplied specs, so a direct weight comparison cannot be made. Installers should verify rack weight ratings before deploying either unit and should consult the IEC model's datasheet for its physical dimensions.
