APC by Schneider Electric SRT5KRMTF vs APC by Schneider Electric SRTL5KRMTF: Specification Comparison
Both the SRT5KRMTF and SRTL5KRMTF are 2U rackmount step-down isolation transformers from APC's Smart-UPS line, designed to convert 208V input to 120V output at 5000VA capacity for use with compatible Smart-UPS units. Neither is a standalone UPS — both are transformer accessories that pair with APC Smart-UPS SRT or SRTL series UPS platforms respectively. This comparison examines their physical, electrical, and environmental specifications to help installers determine which transformer is the correct companion for their existing or planned UPS platform.

Do the SRT5KRMTF and SRTL5KRMTF share identical electrical specifications?
Based on the provided specifications, both transformers are electrically identical across every measured parameter. Each accepts 208V input via a NEMA L6-30P plug, delivers 120V output across 12 NEMA 5-20R receptacles, and carries a 5000VA load capacity. Maximum line current is 24A on both units, with input current limits of 30A. No differences in waveform type, efficiency rating, or harmonic distortion figures are present in the provided specifications for either model — buyers cannot differentiate the two on electrical output performance from the data supplied.
Are there any physical or installation differences between the SRT5KRMTF and SRTL5KRMTF?
The provided specifications show no physical differentiation between the two models. Both occupy 2U of rack space, weigh 95.00 lb (43.09 kg), measure 3.50 in (8.9 cm) in the listed dimension, ship with 1 cable, are black in color, and mount horizontally in a rack in the front position. Rack depth, width, and full chassis dimensions beyond the single 3.50 in figure are not specified for either model. Installers should verify rack depth clearance independently, as only one dimensional value is present in the supplied data for both units.
Do the SRT5KRMTF and SRTL5KRMTF support the same operating and storage environments?
Environmental specifications are identical between both units as provided. Operating relative humidity is 0–95% non-condensing and operating altitude is 0–10,000 ft for both. Storage conditions are also matched: 5–113°F (−15–45°C) ambient temperature, 0–95% non-condensing relative humidity, and 0–50,000 ft (0–15,240 m) altitude. No operating temperature range is specified for either model in the provided data — a notable gap for installers sizing cooling in enclosed rack environments. Buyers should consult APC datasheets directly for operating temperature limits before deployment.
Which should you choose: the SRT5KRMTF or the SRTL5KRMTF?
Our take: The SRT5KRMTF and SRTL5KRMTF cannot be meaningfully differentiated on the basis of the provided specifications, as every electrical, physical, and environmental parameter listed is identical between the two models. The sole distinction apparent from the product names and SKUs is UPS platform compatibility: the SRT5KRMTF is designed for the APC Smart-UPS SRT series, while the SRTL5KRMTF is designed for the APC Smart-UPS Ultra On-Line SRTL series. Selecting the wrong transformer for your UPS platform is the primary risk — pairing an SRTL5KRMTF with an SRT-series UPS, or vice versa, may result in incompatibility. Buyers must match the transformer SKU to their specific UPS platform. No spec-based preference for one over the other can be stated from the data supplied; the decision is driven entirely by which APC UPS series is already installed or planned.

Frequently Asked Questions
Which should you choose: the SRT5KRMTF or the SRTL5KRMTF?
The SRT5KRMTF and SRTL5KRMTF cannot be meaningfully differentiated on the basis of the provided specifications, as every electrical, physical, and environmental parameter listed is identical between the two models. The sole distinction apparent from the product names and SKUs is UPS platform compatibility: the SRT5KRMTF is designed for the APC Smart-UPS SRT series, while the SRTL5KRMTF is designed for the APC Smart-UPS Ultra On-Line SRTL series. Selecting the wrong transformer for your UPS platform is the primary risk — pairing an SRTL5KRMTF with an SRT-series UPS, or vice versa, may result in incompatibility. Buyers must match the transformer SKU to their specific UPS platform. No spec-based preference for one over the other can be stated from the data supplied; the decision is driven entirely by which APC UPS series is already installed or planned.
Is the SRT5KRMTF or SRTL5KRMTF better for larger deployments?
Based on the provided specifications, both transformers are rated identically at 5000VA with 12 NEMA 5-20R outlets, 24A max line current, and 30A input current limits. Neither has a capacity advantage over the other from the data supplied. The correct choice for a larger deployment is determined solely by which APC Smart-UPS platform — SRT or SRTL — is being deployed, not by any electrical or physical superiority of one transformer over the other.
Can I use the SRT5KRMTF with an SRTL-series UPS or vice versa?
The product names indicate platform-specific compatibility — the SRT5KRMTF is designated for APC Smart-UPS SRT series UPS units, while the SRTL5KRMTF is designated for the Smart-UPS Ultra On-Line SRTL series. Cross-platform use is not supported by the provided specifications and should not be assumed. APC's compatibility documentation should be consulted before installation to confirm which transformer SKU is required for a specific UPS model.
Do the SRT5KRMTF and SRTL5KRMTF have the same weight and rack space requirements?
Yes — both units weigh 95.00 lb (43.09 kg) and occupy 2U of rack space, with a listed height of 3.50 in (8.9 cm). Only one dimension is provided in the available specifications for each model; full chassis depth and width are not listed. Installers should verify complete dimensional data from APC's official datasheet before rack planning, particularly for depth-constrained enclosures.
