Vertiv AS3A0NCVGNNXLKB 5kVA Scalable to 15kVA N+1 UPS System
Overview
The Vertiv AS3A0NCVGNNXLKB is a hardwire-connected online UPS module starting at 5kVA/4.5kW with a built-in growth path to 15kVA/13.5kW — the right foundation for data closets, security head-end rooms, and industrial control environments where you need protected power today and room to scale without a rip-and-replace tomorrow. Unlike rack UPS units with receptacle output banks, the AS3A0NCVGNNXLKB is purpose-built for hardwire integration: both input and output terminate via line-line-ground connections, making it appropriate for permanently wired distribution panels and custom PDU deployments. Optional PODs (Power Output Devices) extend outlet flexibility without compromising the hardwire core architecture.

Key Features
- 5kVA / 4.5kW Starting Capacity: covers a realistic head-end room load — a mix of NVRs, PoE switches, access control panels, and network gear — without the upfront cost of buying peak capacity you won't use for years. Size to today's draw, not tomorrow's maximum.
- Scalable to 15kVA / 13.5kW: when the next camera expansion or server refresh hits, this platform grows with the load. Reaching 15kVA in modular steps avoids procurement cycles and parallel-unit wiring headaches. Check the AS3A0NCVGNNXLKB family matrix to understand which intermediate models bridge the gap.
- N+1 Redundancy Architecture: adding a redundant module means no single UPS failure takes down the protected load. For 24/7 surveillance infrastructure — video recording, access control servers, intercoms — N+1 is the difference between a maintenance window and an unplanned outage.
- 15-Minute Full-Load Runtime: at 5kVA full load, the internal battery delivers 15 minutes of runtime. That's long enough for an orderly NVR shutdown or for a generator to stabilize and pick up the load — not indefinite runtime, but the correct buffer for generator-backed installations and controlled shutdown scripts.
- 38-Minute Half-Load Runtime: at 50% load (roughly 2.25kW — typical for a mid-density security rack), runtime extends to 38 minutes. If your actual draw sits well below nameplate, this unit provides substantially more bridge time than the full-load figure suggests.
- Hardwire Input (L-L-G): line-line-ground hardwire connection on the input side eliminates the plug/receptacle failure point in high-current installations and meets the requirements of most commercial electrical codes for permanently installed equipment above 20A. Coordinate with your licensed electrician during site planning — this is not a plug-in unit.
- Hardwire Output with Optional PODs: the hardwired output keeps the core installation clean and code-compliant, while optional PODs let you add managed outlet branches downstream. This matters for selective load shedding — you can de-energize non-critical loads (monitors, lighting) while keeping NVRs and access control live during a battery event.
Integration and Compatibility
As a hardwire UPS system, the AS3A0NCVGNNXLKB integrates into permanently wired electrical infrastructure rather than plugging into an existing outlet. Electrical coordination is required: input voltage and circuit breaker sizing must match the L-L-G hardwire specification. The optional POD accessories extend the output architecture for environments where some receptacle-based devices must also be protected. For larger loads or tighter runtime requirements, the same product family scales to 10kVA (AS3B series) and 15kVA (AS3C series) with parallel runtime specs — compare models against your actual load profile and generator transfer time before specifying. When planning battery runtime for NVR and server closets, use half-load runtime as your working figure unless you've measured actual draw at full camera capacity. For parallel redundancy planning and UPS system design guidance, consult pre-sales engineering before finalizing the build of materials.
Frequently Asked Questions
Q: What is the runtime of the AS3A0NCVGNNXLKB at full load versus half load?
A: At full load (5kVA / 4.5kW), the AS3A0NCVGNNXLKB delivers 15 minutes of runtime. At half load (approximately 2.25kW), runtime extends to 38 minutes. Actual runtime will vary based on battery age and condition.
Q: Does this unit use a standard plug or does it require hardwire installation?
A: Both input and output connections are hardwire (L-L-G) — this is not a plug-in unit. Installation must be performed by a licensed electrician and integrated into a permanently wired electrical distribution system. Optional PODs can add receptacle outlets on the output side.
Q: Can the AS3A0NCVGNNXLKB scale beyond 5kVA without replacing the unit?
A: Yes. The platform is scalable to 15kVA / 13.5kW. Scaling options within the AS3 product family allow capacity to be increased incrementally — refer to the full model matrix (AS3A, AS3B, AS3C series) to identify the correct upgrade path for your load growth.
Q: What does N+1 mean for this UPS, and how does redundancy work?
A: N+1 means one additional UPS module beyond the minimum required to support the load. If one module fails, the remaining unit(s) carry the load without interruption. This architecture is appropriate for mission-critical installations — video surveillance infrastructure, access control servers — where any unplanned downtime is unacceptable.
Q: What input voltage configuration does the AS3A0NCVGNNXLKB require?
A: The input is line-line-ground (L-L-G) hardwire. Specific voltage requirements should be confirmed against the manufacturer's full datasheet and coordinated with your electrical contractor prior to installation.
Q: How does this model compare to the AS3A0NCUGNNXLKB in the same family?
A: Both are 5kVA / 4.5kW units with the same hardwire I/O and 15kVA scalability ceiling. The key difference is runtime: the AS3A0NCVGNNXLKB provides 15 minutes at full load and 38 minutes at half load, while the AS3A0NCUGNNXLKB delivers only 5 minutes at full load and 14 minutes at half load. Choose the AS3A0NCVGNNXLKB when generator transfer time or controlled shutdown sequences require the longer battery bridge.
The runtime delta between sibling models in this family is the first thing I check when speccing a unit for a security head-end, and on the AS3A0NCVGNNXLKB it matters: 15 minutes at full load versus 5 minutes on the NCUG variant gives you a workable generator transfer window rather than a panic shutdown. For a 5kVA load in a camera-dense installation, that extra 10 minutes is the difference between a graceful NVR checkpoint flush and corrupted video indexes.
Technical Highlights:
- 38-Minute Half-Load Runtime: in a real security rack — NVRs spinning drives, a managed PoE switch, an access control server — you're rarely at nameplate load. At 50% (2.25kW), the battery bridge is 38 minutes, which easily covers a generator cold-start plus stabilization time in most commercial installations.
- Scalable to 15kVA / 13.5kW: the AS3 platform lets you add capacity in the same footprint as the installation grows — camera expansions, server consolidation, additional access control head-ends — without rewiring the protected distribution panel each time.
- Hardwire L-L-G Input and Output: eliminates the receptacle as a failure point in high-current permanent installations. Combined with optional PODs on the output side, you get code-compliant wiring to the panel plus the flexibility to shed non-critical receptacle loads during a battery event.
Deployment Considerations:
- Electrical rough-in must be planned before equipment delivery — L-L-G hardwire requires a licensed electrician and dedicated circuit sizing. Budget the electrical labor into the project timeline, not as an afterthought.
- The 15-minute full-load runtime is sized for generator-backed installations, not indefinite island operation. If the site has no generator and mains outages run longer than 15 minutes, plan for external battery extension or a higher-runtime sibling model.
This unit is best positioned for commercial security infrastructure rooms — camera head-ends with 10–40 channels, access control servers, and managed switching — in facilities that are generator-backed and need a modular UPS platform they won't outgrow in the first three years.
