Vertiv AS6B0NCWGNNXLKB 10kVA Scalable UPS with N+1 Redundancy
Overview
The Vertiv AS6B0NCWGNNXLKB is a 10kVA / 9.0kW hardwire uninterruptible power supply built for medium-density data rooms, network equipment rooms, and critical infrastructure deployments where scalability and redundancy are non-negotiable from day one. Starting at 10kVA with a clear upgrade path to 20kVA / 18.0kW, this unit is engineered to grow alongside your load — without requiring a full system replacement when capacity demands increase. Hardwire input (L-L-N-G) and hardwire output with optional PODs make this a fit for permanent, infrastructure-grade installations rather than plug-and-play desktop scenarios.
For teams planning phased deployments or protecting loads that will expand over a 3–5 year horizon, the AS6B0NCWGNNXLKB earns its place in the rack by eliminating the costly forklift upgrade that plagues fixed-capacity UPS platforms.
Key Features
- 10kVA / 9.0kW Starting Capacity: Enough headroom for mid-size server rooms, network closets, or consolidation of edge compute loads. At 9.0kW true power output, you can size loads realistically without padding for a unit running at 40% utilization.
- Scalable to 20kVA / 18.0kW: When load grows — new servers, expanded switching infrastructure, added storage — the platform scales to 20kVA without replacing the core unit. That means your initial capital investment carries forward rather than getting written off at the next refresh cycle.
- N+1 Redundancy Architecture: The N+1 design means a second unit can be added to the system to provide redundancy — if the primary unit faults, the secondary carries the load without interruption. For environments where downtime has a hard dollar cost per minute, this is the architecture to specify.
- 10-Minute Full-Load Runtime: At full 10kVA load, the AS6B0NCWGNNXLKB delivers 10 minutes of runtime — enough for an orderly generator transfer or graceful shutdown sequence on a properly sized data room. Compare this to sibling models: the AS6B0NCVGNNXLKB (same kVA, same scalability ceiling) delivers only 5 minutes at full load, so if your generator transfer time exceeds 5 minutes, the 'W' battery variant is the model to specify.
- 27-Minute Half-Load Runtime: At 50% load (5kVA / 4.5kW), runtime extends to 27 minutes — meaningful for environments where not all circuits are simultaneously loaded, or where tiered shutdown sequences allow non-critical loads to be shed first.
- Hardwire Input (L-L-N-G): This is a permanent installation unit, not a plug-in device. Hardwire input means it integrates cleanly into your electrical panel infrastructure, avoids NEMA outlet ampacity limits, and supports the high continuous current draw that 10kVA loads require. Plan for a licensed electrician in your installation scope.
- Hardwire Output with Optional PODs: Output is hardwired as well, with optional Power Output Distribution (POD) modules available to distribute power to downstream equipment. This gives you flexibility in how you route and distribute protected power without being locked into a fixed receptacle layout.
Integration and Compatibility
The AS6B0NCWGNNXLKB sits within Vertiv's APS scalable UPS family, which spans from 5kVA (AS5A0NCUGNNXLKB) through 20kVA (AS6D0NCJGNNXLKB). All models in the AS6-series share the same 20kVA / 18.0kW scalability ceiling, which means planning around a common platform is straightforward when standardizing across multiple rooms or facilities. The optional POD output architecture also allows integrators to adapt the output distribution to specific rack or row layouts without rewiring the UPS itself.
For UPS systems in this power class, hardwire installations typically pair with power distribution units downstream, and coordination with a Vertiv system architecture is straightforward given the consistent platform design across the APS line. Integrators specifying this unit alongside network infrastructure builds should factor in the POD accessory options early — retrofitting output distribution after installation adds unnecessary labor cost.
Frequently Asked Questions
Q: What is the difference between the AS6B0NCWGNNXLKB and the AS6B0NCVGNNXLKB?
A: Both models are 10kVA / 9.0kW with a 20kVA scalability ceiling and hardwire I/O, but the battery configurations differ. The AS6B0NCVGNNXLKB provides 5 minutes at full load and 16 minutes at half load. The AS6B0NCWGNNXLKB provides 10 minutes at full load and 27 minutes at half load — the right choice when your generator transfer time or shutdown sequence requires more than 5 minutes of bridge time.
Q: What input wiring configuration does the AS6B0NCWGNNXLKB require?
A: The unit requires a hardwire L-L-N-G input — line, line, neutral, ground. This is a permanent installation requiring a licensed electrician. It is not compatible with standard NEMA plug configurations.
Q: Can the AS6B0NCWGNNXLKB be expanded beyond 10kVA without replacing the unit?
A: Yes. The unit is scalable to 20kVA / 18.0kW within the same platform, allowing capacity expansion as load requirements grow without a full system replacement.
Q: What runtime should I expect at half load on the AS6B0NCWGNNXLKB?
A: At 50% load (approximately 5kVA / 4.5kW), the unit delivers 27 minutes of runtime. At full 10kVA load, runtime is 10 minutes.
Q: Does the AS6B0NCWGNNXLKB support N+1 redundancy?
A: Yes. The system is designed for N+1 redundancy, allowing a second unit to be paired to provide failover protection if the primary unit experiences a fault.
Q: What output options are available on the AS6B0NCWGNNXLKB?
A: Output is hardwired. Optional Power Output Distribution (POD) modules are available to provide flexible downstream power distribution without altering the core UPS wiring.
The spec that sets the AS6B0NCWGNNXLKB apart from its closest sibling is straightforward: 10 minutes at full load versus 5 minutes on the AS6B0NCVGNNXLKB. That 5-minute delta sounds modest until you're in a generator transfer scenario and your transfer switch takes 7–8 seconds plus your generator spin-up adds another 30–45 seconds — and then your shutdown scripts need time to run graceful sequences across 20 servers. The 'W' battery variant in this family was clearly spec'd for exactly that gap.
Technical Highlights:
- 10kVA / 9.0kW Capacity: Real-world deployments at 80% utilization put you at 7.2kW of protected load — a comfortable fit for a mid-density server room running 8–12 rack units of compute and switching infrastructure.
- 20kVA Scalability Ceiling: The 2x headroom from 10kVA to 20kVA / 18.0kW means you can right-size today without burning capital on capacity you won't use for 18 months, then expand on the same platform rather than writing off the original investment.
- 27-Minute Half-Load Runtime: At 5kVA, you have nearly half an hour — long enough for extended generator failures or staggered shutdown sequences where non-critical loads are shed in tiers.
Deployment Considerations:
- Hardwire L-L-N-G input means your install scope must include a licensed electrician and panel work — budget this into your project timeline, especially if permitting is required in your jurisdiction.
- The optional POD output modules are worth specifying at initial install rather than retrofit — adding distribution after the fact in a live equipment room is significantly more disruptive than wiring it correctly on day one.
This unit is a strong fit for a phased edge data room buildout — a financial services branch office, a manufacturing plant control room, or a campus network hub where load will grow in 12–18 month increments and replacing the UPS at each phase is not an acceptable operational model.
