APC by Schneider Electric SURT20KRMXLT-TF5 vs APC by Schneider Electric SURT20KRMXLT-1TF10K: Specification Comparison
Both the SURT20KRMXLT-TF5 and SURT20KRMXLT-1TF10K belong to APC's Smart-UPS RT 20kVA rackmount line, targeting data centers and critical infrastructure running at 208V. The key distinction is that the SURT20KRMXLT-1TF10K bundles a 10kVA step-down transformer, enabling simultaneous 120V and 208V output, while the SURT20KRMXLT-TF5 provides 208V output with a different outlet configuration. Buyers choosing between these are evaluating outlet mix, rack space consumption, runtime, and whether integrated voltage step-down is operationally necessary.

How do the two units compare on power capacity, output voltage options, and outlet configuration?
The SURT20KRMXLT-1TF10K specifies 20 kVA / 16 kW capacity with dual output voltages: 120V AC and 208V AC, enabled by its integrated 10kVA step-down transformer. It provides 11 total outlets. Load capacity in VA and watts is not stated in the SURT20KRMXLT-TF5 specs provided.
The SURT20KRMXLT-TF5 lists 12x 5-20R and 4x L6-20R and 1x L6 receptacles in its product name, covering both 120V (5-20R) and 208V (L6-20R/L6) loads directly—without a separate step-down transformer. Total outlet count beyond the named types is not specified in the provided specs.
Buyers powering mixed 120V/208V loads should note that the SURT20KRMXLT-TF5's outlet mix is itemized by receptacle type, while the SURT20KRMXLT-1TF10K reports only a total of 11 outlets with no per-receptacle breakdown provided.
What runtime and battery recharge performance can installers expect under load?
The SURT20KRMXLT-1TF10K provides specified runtime figures: 4.90 minutes at full load and 15.30 minutes at half load, with a typical battery recharge time of 2.50 hours. Battery chemistry is Lead Acid.
The SURT20KRMXLT-TF5 specifies battery type as maintenance-free sealed Lead-Acid with suspended electrolyte (leakproof), but no runtime figures—full load, half load, or recharge time—are present in the provided specifications.
For sites where guaranteed runtime under known load conditions is a procurement requirement, the SURT20KRMXLT-1TF10K is the only unit of the two with documented runtime data in the specs supplied.
How do the two units differ in rack footprint, physical dimensions, weight, and management capabilities?
The SURT20KRMXLT-TF5 occupies 14U of rack space. Physical dimensions are given as 62.2H x 43.2W x 77.3D cm (approximately 24.5" H x 17" W x 30.4" D). Weight is not specified in the provided data.
The SURT20KRMXLT-1TF10K occupies 16U—two rack units more—and measures 27.9" H x 17" W x 30.4" D, weighing 766.61 lb. The added rack height is consistent with the integrated step-down transformer.
Both units share a 17" width. Management: the SURT20KRMXLT-TF5 includes a Web/SNMP Management Card in the box along with RS-232 cable and software CD. The SURT20KRMXLT-1TF10K is listed as SNMP Manageable but the provided specs do not confirm whether a management card is included or sold separately. The SURT20KRMXLT-1TF10K carries a stated 2-year warranty; warranty for the SURT20KRMXLT-TF5 is not specified in the provided data.
Which should you choose: the SURT20KRMXLT-TF5 or the SURT20KRMXLT-1TF10K?
Our take: The SURT20KRMXLT-TF5 is the stronger choice when rack space is constrained and the site already supplies or can distribute 208V and 120V feeds independently, as it saves 2U (14U vs 16U) and ships with a Web/SNMP Management Card included—avoiding a separate accessory purchase. The SURT20KRMXLT-1TF10K is the stronger choice when a single UPS must serve mixed-voltage loads via an integrated 10kVA step-down transformer, and when documented runtime guarantees matter: it specifies 4.90 minutes at full load and 15.30 minutes at half load—figures absent from the TF5's provided specs. At 766.61 lb, the 1TF10K demands serious floor-load planning that the TF5's unspecified weight does not clarify. Facilities running pure 208V infrastructure with existing management infrastructure favor the TF5; mixed 120V/208V environments with no external transformer favor the 1TF10K.

Frequently Asked Questions
Which should you choose: the SURT20KRMXLT-TF5 or the SURT20KRMXLT-1TF10K?
The SURT20KRMXLT-TF5 is the stronger choice when rack space is constrained and the site already supplies or can distribute 208V and 120V feeds independently, as it saves 2U (14U vs 16U) and ships with a Web/SNMP Management Card included—avoiding a separate accessory purchase. The SURT20KRMXLT-1TF10K is the stronger choice when a single UPS must serve mixed-voltage loads via an integrated 10kVA step-down transformer, and when documented runtime guarantees matter: it specifies 4.90 minutes at full load and 15.30 minutes at half load—figures absent from the TF5's provided specs. At 766.61 lb, the 1TF10K demands serious floor-load planning that the TF5's unspecified weight does not clarify. Facilities running pure 208V infrastructure with existing management infrastructure favor the TF5; mixed 120V/208V environments with no external transformer favor the 1TF10K.
Does the SURT20KRMXLT-TF5 or SURT20KRMXLT-1TF10K support both 120V and 208V output?
Based on provided specs, the SURT20KRMXLT-1TF10K explicitly supports both 120V AC and 208V AC output via its integrated 10kVA step-down transformer. The SURT20KRMXLT-TF5 lists 5-20R (120V) and L6-20R/L6 (208V) receptacles in its outlet mix, suggesting mixed-voltage output, but no output voltage spec is explicitly stated in the provided data. Confirm with APC documentation before designing a mixed-voltage distribution plan around the TF5.
Which unit takes up less rack space—the SURT20KRMXLT-TF5 or the SURT20KRMXLT-1TF10K?
The SURT20KRMXLT-TF5 is specified at 14U; the SURT20KRMXLT-1TF10K at 16U. The TF5 saves 2U of rack space, which matters in high-density cabinets. The added height of the 1TF10K is attributable to its integrated step-down transformer.
Is the SURT20KRMXLT-1TF10K significantly heavier than the SURT20KRMXLT-TF5?
The SURT20KRMXLT-1TF10K weighs 766.61 lb per the provided specifications, requiring careful floor-load and lifting planning. Weight for the SURT20KRMXLT-TF5 is not present in the provided specifications, so a direct numeric comparison cannot be made from available data alone. Consult APC's published datasheet for the TF5's shipping and operating weight before installation.
