How do the two units differ in power delivery, voltage handling, and outlet configuration?
The SRT3000RMXLA-NC is rated at 3,000 VA / 2,700 W (0.9 power factor), operating on a 120 V input via a NEMA L5-30P plug with an input frequency window of 40–70 Hz. Its nine AC outlets break down as eight NEMA 5-20R receptacles plus one NEMA L5-30R, offering a mix of standard 20 A and twist-lock 30 A output connections. Output voltage THD is specified at 2%, and the crest factor tolerance is listed as 3:1, indicating resilience against non-linear loads common in power-supply-dense IT racks.
The GXT5-3KL630RT2UXL is rated at 3,000 VA / 3,000 W (1.0 power factor), operating on a 208 VAC nominal input via an L6-30P plug. Output is 208 VAC delivered through two L6-15R and two L6-30R receptacles — four outlets total. Output power factor, output THD, crest factor tolerance, surge energy rating, and input frequency range are not provided in the supplied specifications for the Vertiv unit.
The voltage tier difference is the primary compatibility gate: the APC unit is a 120 V product while the Vertiv unit requires a 208 V circuit. These two units target different branch-circuit infrastructure and are not interchangeable on the same panel circuit. Outlet counts also differ significantly: nine (APC) versus four (Vertiv).
Which unit offers better operating efficiency, and how do their environmental and compliance specifications compare?
The GXT5-3KL630RT2UXL specifies up to 98% efficiency in Active ECO Mode and up to 95% efficiency in on-line (double-conversion) mode. An operating temperature range of +32 to +122 °F (0 to +50 °C) is stated. The unit carries ENERGY STAR 2.0 certification, UL1778 listing, c-UL listing, RoHS2 compliance, and REACH compliance.
The SRT3000RMXLA-NC does not include efficiency percentages, operating temperature range, or regulatory certification data in the provided specifications. Surge energy rating (340 J) and output THD (2%) are available, but direct efficiency figures are absent.
On the efficiency and compliance axis the Vertiv unit has substantially more documented specification data. Buyers operating in temperature-sensitive environments or requiring ENERGY STAR certification for procurement compliance will find the Vertiv specs directly actionable; the APC unit's corresponding figures are not available from the provided data and would need to be sourced from the manufacturer's datasheet before a direct efficiency comparison can be made.
How do the management, communications, and integration options compare between the two units?
The SRT3000RMXLA-NC lists web-based management as a built-in feature, along with audible alarms and auto-restart. No detail on communication card type, interface ports, or protocol support is included in the provided specifications.
The GXT5-3KL630RT2UXL provides USB, RS485, RS232, a terminal block, and an external battery connector as standard interface options. SNMP and web management are supported via the optional Vertiv RDU101 communications card (not included). The control panel is described as a full-color graphic LCD with gravity-sensing orientation. Out-of-band management is available via the serial connection.
The APC unit states web management as included out of the box; the Vertiv unit requires an additional optional card (RDU101) to enable SNMP and web management, but provides a broader set of physical interface options (RS485, RS232, terminal block) that can suit diverse monitoring architectures. Installers integrating into existing SNMP-based monitoring platforms should confirm card availability and cost for the Vertiv unit. Protocol specifics for the APC unit's built-in web management are not detailed in the provided specifications.
Which should you choose: the SRT3000RMXLA-NC or the GXT5-3KL630RT2UXL?
Our take: The SRT3000RMXLA-NC is the stronger choice when the installation runs on 120 V branch circuits and requires a higher outlet count for protecting multiple devices. Its nine outlets (8× NEMA 5-20R + 1× NEMA L5-30R) versus the Vertiv's four outlets (2× L6-15R + 2× L6-30R) represent a meaningful difference in load connectivity, and its built-in web management avoids the cost of an add-on card. Conversely, the GXT5-3KL630RT2UXL is the stronger choice for 208 V infrastructure: it delivers a 1.0 power factor (3,000 W output versus 2,700 W), documents up to 98% ECO-mode and 95% on-line efficiency, and holds ENERGY STAR 2.0, UL1778, and RoHS2 certifications — none of which are present in the APC's provided specifications. The two units are not interchangeable: voltage tier (120 V vs. 208 V) is a hard infrastructure dependency that must be resolved before any other criterion applies.

Frequently Asked Questions
Which should you choose: the SRT3000RMXLA-NC or the GXT5-3KL630RT2UXL?
The SRT3000RMXLA-NC is the stronger choice when the installation runs on 120 V branch circuits and requires a higher outlet count for protecting multiple devices. Its nine outlets (8× NEMA 5-20R + 1× NEMA L5-30R) versus the Vertiv's four outlets (2× L6-15R + 2× L6-30R) represent a meaningful difference in load connectivity, and its built-in web management avoids the cost of an add-on card. Conversely, the GXT5-3KL630RT2UXL is the stronger choice for 208 V infrastructure: it delivers a 1.0 power factor (3,000 W output versus 2,700 W), documents up to 98% ECO-mode and 95% on-line efficiency, and holds ENERGY STAR 2.0, UL1778, and RoHS2 certifications — none of which are present in the APC's provided specifications. The two units are not interchangeable: voltage tier (120 V vs. 208 V) is a hard infrastructure dependency that must be resolved before any other criterion applies.
Can I use either of these UPS units on a standard 120 V outlet?
No. Only the APC SRT3000RMXLA-NC is designed for 120 V input (NEMA L5-30P plug). The Vertiv GXT5-3KL630RT2UXL requires a 208 VAC circuit with an L6-30P receptacle. Connecting the Vertiv unit to a 120 V circuit is outside its specified input voltage and would not be supported.
Does the Vertiv GXT5-3KL630RT2UXL include SNMP management out of the box?
No. According to the provided specifications, SNMP and web management on the GXT5-3KL630RT2UXL require the optional Vertiv RDU101 communications card, which is not included as standard. USB, RS485, RS232, and terminal block interfaces are included. The APC SRT3000RMXLA-NC lists web-based management as a built-in feature, though the specific protocol details are not enumerated in the provided specifications.
Which unit is more suitable for a high-density rack with many individual devices to protect?
The APC SRT3000RMXLA-NC provides nine AC outlets (eight NEMA 5-20R and one NEMA L5-30R), making it better suited to racks with multiple individual devices requiring direct UPS-connected receptacles. The Vertiv GXT5-3KL630RT2UXL provides four outlets (two L6-15R and two L6-30R), which is more typical for downstream PDU or high-draw single-device topologies. Outlet count alone does not determine protected capacity; load calculations per circuit must still be performed.
