How do the power architecture and output options differ between the SRT5KRMXLT-5KTF and the GXT5LI-5KL630RT3UXLN?
Both units share a 5000VA double-conversion online topology, providing zero-transfer-time protection against input anomalies. The APC SRT5KRMXLT-5KTF accepts 208V AC single-phase input and incorporates an integrated 208V-to-120V step-down transformer, enabling it to supply twelve NEMA 5-20R (120V) outlets alongside two NEMA L6-20R and two NEMA L6-30R (208V) outlets—a total of sixteen output connections across two voltages. This makes it a direct fit for mixed-voltage racks without a separate transformer appliance.
The Vertiv GXT5LI-5KL630RT3UXLN accepts 200–240V AC input via an L6-30P plug and delivers 208V AC output (configurable 200–240V AC), rated at 5000VA and 4900W. Output connection count and receptacle types are not specified in the provided data. Buyers requiring 120V outlets for NEMA-standard equipment would need additional PDUs or adapters downstream of the Vertiv unit, whereas the APC's transformer eliminates that need natively.
What are the differences in battery technology, physical footprint, and weight between the two units?
Battery chemistry is the sharpest differentiator here. The APC SRT5KRMXLT-5KTF uses a sealed lead-acid battery, a mature and widely serviceable technology, backed by a 24-month battery warranty. The Vertiv GXT5LI-5KL630RT3UXLN uses lithium-ion chemistry, which typically provides a longer service life, faster recharge, and significantly better weight-to-capacity ratio—though cycle-life figures and battery warranty duration are not stated in the provided specifications.
The weight difference is substantial: the APC unit weighs 217.99 lb (98.88 kg), driven in part by its integrated transformer and lead-acid battery; the Vertiv weighs 103 lb—roughly half. For rack loading, floor-weight planning, and one- or two-person installation, this gap is operationally significant. In terms of rack space, the APC occupies 5U (8.58 in H × 17.01 in W × 28.31 in D), while the Vertiv is 3U (5.25 in H × 16.9 in W × 35 in D), trading height for depth. Buyers with shallow racks should verify the Vertiv's 35-inch depth against their cabinet clearance.
How do network management capabilities, certifications, and warranty terms compare?
The APC SRT5KRMXLT-5KTF includes a 10/100 BaseT network management port, allowing integration with APC's network management card ecosystem for SNMP monitoring, remote shutdown scripting, and facility management system tie-ins. Surge energy absorption is rated at 480 J. The unit carries a 36-month UPS warranty and a 24-month battery warranty. No regulatory certifications are listed in the provided specifications.
The Vertiv GXT5LI-5KL630RT3UXLN carries a comprehensive set of agency approvals: IEC 62040-1:2008+A1 2013, IEC 62619 1st Ed., IEC 62040-2 2nd Ed., IEC 61000-3-2, IEC 61000-3-12, CISPR 22 Class A, FCC Part 15 Class A, and UL 1778. The IEC 62619 listing is specific to lithium-ion battery safety—relevant for facilities with strict battery-chemistry policies or insurance requirements. Network management interface type and warranty duration are not stated in the provided specifications, which is a gap buyers should resolve with Vertiv before purchase. Operating temperature is explicitly rated at 32°F–104°F (0°C–40°C) with a 10% derating at 50°C; the APC's operating temperature range is not provided in the supplied specs.
Which should you choose: the SRT5KRMXLT-5KTF or the GXT5LI-5KL630RT3UXLN?
Our take: The SRT5KRMXLT-5KTF is the stronger choice when a single rack must serve both 208V and 120V loads simultaneously, thanks to its integrated step-down transformer and sixteen mixed-voltage output connections—a capability the GXT5LI-5KL630RT3UXLN does not offer natively per the supplied specifications. However, three spec deltas favor the Vertiv: it is roughly half the weight (103 lb vs. 217.99 lb), occupies 2U less rack space (3U vs. 5U), and carries lithium-ion chemistry with a documented list of agency certifications including UL 1778 and IEC 62619, while the APC's certifications are absent from the provided data. Buyers prioritizing rack-load limits, installation ease, or regulated-environment compliance should weight the Vertiv heavily. Buyers running mixed 120V/208V gear in a single cabinet, or those standardized on APC's network management card infrastructure, will find the APC's transformer integration and network port directly address their architecture without additional hardware.

Frequently Asked Questions
Which should you choose: the SRT5KRMXLT-5KTF or the GXT5LI-5KL630RT3UXLN?
The SRT5KRMXLT-5KTF is the stronger choice when a single rack must serve both 208V and 120V loads simultaneously, thanks to its integrated step-down transformer and sixteen mixed-voltage output connections—a capability the GXT5LI-5KL630RT3UXLN does not offer natively per the supplied specifications. However, three spec deltas favor the Vertiv: it is roughly half the weight (103 lb vs. 217.99 lb), occupies 2U less rack space (3U vs. 5U), and carries lithium-ion chemistry with a documented list of agency certifications including UL 1778 and IEC 62619, while the APC's certifications are absent from the provided data. Buyers prioritizing rack-load limits, installation ease, or regulated-environment compliance should weight the Vertiv heavily. Buyers running mixed 120V/208V gear in a single cabinet, or those standardized on APC's network management card infrastructure, will find the APC's transformer integration and network port directly address their architecture without additional hardware.
Can the SRT5KRMXLT-5KTF power standard 120V NEMA equipment directly, or do I need a separate PDU?
Yes. The SRT5KRMXLT-5KTF includes an integrated 208V-to-120V step-down transformer and provides twelve NEMA 5-20R (120V) receptacles directly on the unit, so standard North American 120V equipment can plug in without a separate PDU or external transformer. The GXT5LI-5KL630RT3UXLN outputs 208V AC; output receptacle types are not specified in the provided data, so buyers should confirm directly with Vertiv whether 120V outlets are available.
Is the GXT5LI-5KL630RT3UXLN significantly easier to install and manage in a dense rack than the SRT5KRMXLT-5KTF?
From a weight and rack-unit standpoint, yes. The Vertiv weighs 103 lb versus 217.99 lb for the APC—a difference that affects both lift requirements and rack floor-load calculations. It also occupies 3U versus 5U, freeing two rack units. However, the Vertiv is deeper (35 in vs. 28.31 in), which may matter in shallow or mid-depth cabinets. For network management, the APC lists a 10/100 BaseT port; the Vertiv's management interface is not described in the provided specifications.
Which unit is better suited for facilities that require formal safety certifications for lithium-ion batteries?
The GXT5LI-5KL630RT3UXLN is the appropriate choice. It explicitly lists IEC 62619 1st Ed. certification, which is the international safety standard for secondary lithium cells and batteries used in stationary applications—a requirement increasingly enforced by insurers and AHJs for Li-ion UPS installations. The SRT5KRMXLT-5KTF uses lead-acid chemistry, so IEC 62619 is not applicable to it; its certification listings are not provided in the supplied specifications.
