Vertiv AS3C0NCXGNNXLKB 15kVA Scalable 3-Phase UPS
Overview
The Vertiv AS3C0NCXGNNXLKB is a 15kVA / 13.5kW hardwire-input UPS configured for N+1 redundancy within a scalable platform that tops out at 15kVA / 13.5kW total system capacity. If you're sizing power protection for a mid-density data closet, a surveillance server room, or a critical network edge deployment and need a path to redundancy without a full forklift upgrade, this unit is worth a close look. Hardwire input (L-L-G) and output keep the installation clean and permanent — no inlet adapters, no exposed plugs on a 15kVA load. Optional POD expansion output extends runtime without swapping the base unit.
Key Features
- 15kVA / 13.5kW Active Capacity: At full nameplate load, the AS3C0NCXGNNXLKB delivers 13.5kW of real power — enough headroom for a fully populated rack of servers, a mid-size NVR stack with PoE switches, or a converged IT/OT edge node. Running at half load (6.75kW) buys 22 minutes of runtime, which covers a controlled shutdown on most enterprise systems without generator dependency.
- 8-Minute Full-Load Runtime: At 100% load, you get 8 minutes — the longest full-load runtime available in the 15kVA tier of this family. The sibling AS3C0NCWGNNXLKB drops to 5 minutes at full load, so if you're designing for graceful shutdown under realistic peak draw, this model is the right pick in that tier.
- 22-Minute Half-Load Runtime: At 50% utilization (6.75kW), runtime extends to 22 minutes. Most data closet and surveillance infrastructure loads sit well below nameplate during steady-state operations, which means this runtime figure is closer to real-world than the full-load number. Plan your shutdown scripts and generator spin-up windows around 22 minutes if you're running a typical mixed load.
- Scalable to 15kVA N+1: The platform is architected to scale to 15kVA / 13.5kW system capacity, supporting N+1 redundancy. That means you can add a parallel unit and remove single-point-of-failure risk on the UPS layer without replacing cabling or changing the hardwire infrastructure — a meaningful operational benefit in any 24/7 environment.
- Hardwire L-L-G Input and Output: Both input and output are hardwired (L-L-G), which is the correct termination method for installations at this power class. There are no plug-and-socket connections to fail under vibration or heat cycling. For secured equipment rooms and telecom closets, hardwire also eliminates the risk of accidental disconnection.
- Optional POD-Based Output Expansion: The output architecture supports optional Power Distribution PODs, giving you flexibility to match output receptacle configuration to your rack equipment without modifying the base UPS. This is particularly useful in mixed-load deployments where different equipment strings need different outlet types or circuit protection levels.
Integration and Compatibility
The AS3C0NCXGNNXLKB sits in the Vertiv APS scalable UPS family alongside 5kVA (AS3A-series), 10kVA (AS3B-series), and 15/20kVA variants in both 15kVA and 20kVA scalable platforms. If you are deploying multiple racks under a single UPS infrastructure, the AS4-series (scalable to 20kVA / 18kW) may be worth evaluating for headroom — particularly the Vertiv APS line AS4C and AS4D models which scale to 20kVA with comparable runtime profiles. Within the AS3-series, the two 15kVA options differ only in runtime: this model (AS3C0NCXGNNXLKB) offers 8 minutes at full load versus 5 minutes for the AS3C0NCWGNNXLKB — the sole differentiator between those two SKUs.
For uninterruptible power supply deployments in surveillance infrastructure, physical security control rooms, or converged IT environments, the hardwire I/O and N+1 scalability make this unit suitable for permanent installation in dedicated equipment rooms. Pair with a PDU or POD to distribute output to individual rack loads.
Frequently Asked Questions
Q: What is the difference between the AS3C0NCXGNNXLKB and the AS3C0NCWGNNXLKB?
A: Both are 15kVA / 13.5kW models in the AS3 scalable platform. The AS3C0NCXGNNXLKB delivers 8 minutes of full-load runtime and 22 minutes at half load. The AS3C0NCWGNNXLKB delivers 5 minutes at full load and 15 minutes at half load. If runtime is the selection criterion, the AS3C0NCXGNNXLKB is the longer-runtime option in the 15kVA AS3-series tier.
Q: What is the maximum system capacity this UPS can scale to?
A: The AS3C0NCXGNNXLKB is part of a platform that scales to 15kVA / 13.5kW, supporting N+1 redundancy configurations. If you require a higher ceiling, the AS4-series scales to 20kVA / 18kW.
Q: Does the AS3C0NCXGNNXLKB use plug-in or hardwire connections?
A: Both input and output are hardwired (L-L-G). There are no inlet plugs. Output can be extended via optional POD modules for receptacle distribution.
Q: What runtime can I expect at a typical data closet load below full capacity?
A: At 50% load (approximately 6.75kW), runtime is 22 minutes. Most real-world mixed loads in surveillance or IT closets run well under 100% nameplate, so 22 minutes is a more practical planning number than the full-load 8-minute figure.
Q: Can I add a second unit for redundancy without rewiring?
A: The platform is designed for N+1 scalability within the 15kVA / 13.5kW system ceiling. Adding a parallel unit for redundancy is supported by the platform architecture. Verify site wiring capacity and consult Vertiv documentation for parallel installation requirements specific to your configuration.
The AS3C0NCXGNNXLKB is the runtime-optimized 15kVA option in Vertiv's AS3-series scalable UPS line — and the 8-minute full-load / 22-minute half-load runtime split is the key reason to choose this SKU over the otherwise-identical AS3C0NCWGNNXLKB. When you're protecting surveillance infrastructure that can't afford a hard crash during a utility fault, those extra 3 minutes at full load are the margin between a clean failover and a corrupted NVR write.
Technical Highlights:
- Runtime at Full Load (8 min): Longest full-load runtime in the 15kVA AS3-series. That 3-minute advantage over the AS3C0NCWGNNXLKB is the entire decision point between those two SKUs — worth it when your shutdown scripts or generator spin-up sequences need the buffer.
- Half-Load Runtime (22 min): At 6.75kW, you're at 22 minutes — more than enough for a controlled shutdown sequence on a standard surveillance rack. Size your load to run under 50% nameplate and this number becomes your operational planning baseline.
- N+1 Scalability to 15kVA / 13.5kW: The platform ceiling is 15kVA, so you can parallel a second unit for redundancy without touching the hardwire infrastructure. That's a meaningful lifecycle benefit — phased redundancy without a forklift upgrade.
Deployment Considerations:
- Hardwire L-L-G input and output means this needs a dedicated circuit and a qualified electrician for initial commissioning. Budget for that in your installation timeline — it is not a plug-and-play deployment.
- The AS3-series tops out at 15kVA system capacity. If your load projection puts you above 13.5kW under N+1 accounting, step up to the AS4-series (20kVA ceiling) from the start rather than constraining yourself here.
This unit is the right fit for a permanent physical security control room or surveillance server closet where hardwire installation is standard, the electrical engineer has already sized a dedicated circuit, and you need the longest available runtime at 15kVA before generator handoff.
