APC by Schneider Electric SRT5KRMXLT-5KTF vs APC by Schneider Electric SRT5KRMXLIM: Specification Comparison
Both products are APC Smart-UPS SRT 5000VA rack-mount double-conversion online UPS units — the same power class and device type. However, they serve fundamentally different deployment contexts: the SRT5KRMXLT-5KTF is a step-down transformer model designed for North American 208V-input / 120V-output environments, while the SRT5KRMXLIM is a 230V marine-rated unit targeting shipboard or international installations. A buyer choosing between them is selecting by deployment environment and regional voltage standard rather than by raw UPS capability.

What are the input/output voltage profiles and how do they constrain where each unit can be deployed?
The SRT5KRMXLT-5KTF accepts 208V AC single-phase input and steps it down to 120V output, with 12 NEMA 5-20R, 2 NEMA L6-20R, and 2 NEMA L6-30R receptacles. This makes it specific to North American data center or facility environments where 208V power distribution is standard and downstream equipment runs on 120V.
The SRT5KRMXLIM operates on a 160–275V AC input range with 220–230V output at 50/60 Hz, targeting 230V international or marine environments. Its wide input tolerance (160–275V) and 45–65 Hz frequency acceptance indicate it is engineered for unstable or generator-backed shore power typical on vessels. Output voltage specs for the SRT5KRMXLT-5KTF are not provided in the supplied data beyond the transformer designation.
How do the two units compare on delivered watt capacity, waveform quality, and output power quality metrics?
The SRT5KRMXLIM explicitly states a 4500W (4.5 kW) real power output alongside the 5000VA rating, and specifies pure sine waveform output with output voltage THD of 3% and a crest factor of 3:1. These are quantified power-quality metrics useful for evaluating suitability for sensitive electronics.
The SRT5KRMXLT-5KTF lists 5000VA output capacity but does not provide a watt (W) rating, waveform type, THD percentage, or crest factor in the supplied specifications. Buyers deploying power-sensitive equipment from that unit cannot make a direct power-quality comparison from these spec sheets alone.
Both units share the same surge energy rating of 480 J, which is a directly comparable protection figure.
What are the physical footprint, management interfaces, and any environmental or certification differences between the two models?
The SRT5KRMXLT-5KTF is a 5U rackmount unit measuring 8.58 in H × 17.01 in W × 28.31 in D (218 × 432 × 719 mm) and weighs 217.99 lb (98.88 kg). It includes a 10/100 BaseT network management interface, enabling remote monitoring and management — a spec not present in the SRT5KRMXLIM data.
The SRT5KRMXLIM carries a marine rating ('M' suffix), meaning it is certified for shipboard use under relevant maritime standards. It also specifies Emergency Power Off (EPO), audible alarms, temperature-voltage compensation, and a noise level of 55 dB. Physical dimensions and weight are not provided for the SRT5KRMXLIM in the supplied specifications.
The SRT5KRMXLT-5KTF carries a 36-month UPS warranty and 24-month battery warranty. Warranty terms for the SRT5KRMXLIM are not specified in the supplied data. Both use lead-acid battery technology; battery type for the SRT5KRMXLIM is not stated in the provided specs.
Which should you choose: the SRT5KRMXLT-5KTF or the SRT5KRMXLIM?
Our take: The SRT5KRMXLT-5KTF is the stronger choice when the installation is a North American 208V facility or data center requiring 120V-output receptacles and network-based UPS management. The SRT5KRMXLIM is the appropriate selection for marine, shipboard, or international 230V environments. Three concrete spec deltas define the divide: (1) input voltage — 208V fixed vs. 160–275V wide-range; (2) output voltage — 120V stepped-down vs. 220–230V passthrough; (3) management — the SRT5KRMXLT-5KTF includes a 10/100 BaseT network port; no equivalent is listed for the SRT5KRMXLIM. These are not substitutes. Deploying the SRT5KRMXLIM in a 208V North American rack would be electrically incompatible; deploying the SRT5KRMXLT-5KTF on a vessel would lack maritime certification and the wide input tolerance marine power demands.

Frequently Asked Questions
Which should you choose: the SRT5KRMXLT-5KTF or the SRT5KRMXLIM?
The SRT5KRMXLT-5KTF is the stronger choice when the installation is a North American 208V facility or data center requiring 120V-output receptacles and network-based UPS management. The SRT5KRMXLIM is the appropriate selection for marine, shipboard, or international 230V environments. Three concrete spec deltas define the divide: (1) input voltage — 208V fixed vs. 160–275V wide-range; (2) output voltage — 120V stepped-down vs. 220–230V passthrough; (3) management — the SRT5KRMXLT-5KTF includes a 10/100 BaseT network port; no equivalent is listed for the SRT5KRMXLIM. These are not substitutes. Deploying the SRT5KRMXLIM in a 208V North American rack would be electrically incompatible; deploying the SRT5KRMXLT-5KTF on a vessel would lack maritime certification and the wide input tolerance marine power demands.
Can I use the SRT5KRMXLIM as a drop-in replacement for the SRT5KRMXLT-5KTF in a US data center?
No. The SRT5KRMXLIM is rated for 230V output and a 160–275V input range targeting international and marine voltage standards. The SRT5KRMXLT-5KTF accepts 208V input and outputs 120V via a step-down transformer with NEMA receptacles. The two units have incompatible voltage profiles for North American 208V/120V data center use.
Does the SRT5KRMXLT-5KTF support remote monitoring over the network?
Yes. The SRT5KRMXLT-5KTF specifies a 10/100 BaseT network connection in its supplied specifications. The SRT5KRMXLIM does not list a network management interface in the provided spec data.
Which model is certified for use on ships or vessels?
The SRT5KRMXLIM carries a marine rating (indicated by the 'M' suffix and the product name 'Marine'), along with a wide input voltage tolerance of 160–275V and Emergency Power Off (EPO) — features consistent with maritime certification requirements. The SRT5KRMXLT-5KTF has no marine certification noted in its specifications.
