Vertiv AS6B0NCVGNNXLKB 10kVA Scalable to 20kVA N+1 UPS System
Overview
The Vertiv AS6B0NCVGNNXLKB is a scalable three-phase UPS platform rated at 10kVA with the capacity to grow to 20kVA/18kW in an N+1 redundant configuration — purpose-built for data centers, server rooms, and critical infrastructure environments where a single point of failure is unacceptable. The system operates on 208/120VAC four-wire (L-L-N-G) input and output, fitting standard North American three-phase distribution without requiring a transformer or voltage conversion. If you're sizing power protection for a growing rack environment, this unit gives you room to expand without replacing the chassis.

Key Features
- Scalable to 20kVA/18kW N+1: Start at 10kVA and add capacity as your load grows — the N+1 redundancy architecture means one module can fail without dropping your critical load. This is the right design for environments that cannot tolerate a maintenance window taking down production systems.
- 92% Operating Efficiency: At up to 92% efficiency, this UPS produces substantially less heat than older ferro-resonant or conventional double-conversion designs. Less heat means lower cooling overhead and reduced operating cost — meaningful in 24/7 data center or telecom environments where power waste compounds annually.
- 208/120VAC In/Out — No Step-Down Required: Matching input and output voltage on a 4-wire (L-L-N-G) circuit means it integrates directly into standard three-phase panels serving mixed 208V equipment and 120V branch circuits. No isolation transformer needed, which simplifies the installation and eliminates a potential failure point.
- 510 lb Chassis — Plan the Floor Load: At 510 lbs, the AS6B0NCVGNNXLKB demands a raised-floor or structural slab assessment before installation. The 17 in wide × 34 in deep × 38 in tall footprint fits a standard 19-inch rack bay column, but floor loading must be confirmed with your facilities team before placement.
- Operating Temperature 0°C–40°C (32°F–104°F): Rated for the full range of conditioned data center environments. The upper limit of 40°C means it will operate in spaces with marginal cooling — though sustained operation near that ceiling will stress internal components and should be avoided in permanent deployments.
- Commercial-Grade Three-Phase Architecture: Unlike single-phase UPS units scaled up, this is a purpose-built three-phase system. For enterprise UPS and power conditioning requirements in multi-rack deployments, a true three-phase design provides more balanced loading and better fault isolation than paralleled single-phase units.
Integration and Compatibility
The 208/120VAC four-wire output is compatible with standard North American commercial distribution panels and supports mixed three-phase and single-phase loads off the same bus — useful in environments running a combination of servers (208V) and networking or ancillary equipment (120V). For power planning in larger deployments, review our power planning and UPS sizing guide. Pair this unit with rack-mount PDUs to distribute output across high-density equipment racks cleanly. If your deployment includes security or surveillance infrastructure, consider reviewing network video recorders that depend on clean, conditioned power for continuous recording.
Frequently Asked Questions
Q: What is the maximum power output of the AS6B0NCVGNNXLKB?
A: The system scales to 20kVA/18kW in an N+1 configuration, starting from a 10kVA base. The N+1 design means one redundant module is always available to take over if the active module fails.
Q: What input and output voltage does this UPS support?
A: The AS6B0NCVGNNXLKB accepts and delivers 208/120VAC on a 4-wire (L-L-N-G) circuit — standard North American three-phase distribution. No step-down transformer is required.
Q: How efficient is this UPS under normal operating conditions?
A: Vertiv rates this unit at up to 92% efficiency. That figure reduces heat output compared to older UPS designs and lowers your facility's cooling load proportionally.
Q: What are the physical dimensions and weight?
A: The unit measures 17 in wide × 34 in deep × 38 in tall and weighs 510 lbs. Floor load capacity must be verified before installation — this is not a unit you can place on a standard raised floor tile without a structural assessment.
Q: What is the operating temperature range?
A: The AS6B0NCVGNNXLKB is rated for 0°C to 40°C (32°F to 104°F). It is designed for conditioned indoor environments — not outdoor or unconditioned space installation.
Q: Can this UPS support mixed 208V and 120V loads simultaneously?
A: Yes. The 4-wire (L-L-N-G) output topology supports both line-to-line 208V loads and line-to-neutral 120V loads off the same output bus, which is common in mixed server and networking rack environments.
The AS6B0NCVGNNXLKB is the unit I recommend when a customer is starting at 10kVA but has realistic plans to grow — the scalable-to-20kVA architecture with N+1 redundancy means you're not ripping out and replacing the UPS chassis every time you add racks. The 92% efficiency rating is the other spec I lead with: at this power scale, even a 2–3% efficiency improvement over a competing design translates to thousands of dollars annually in reduced heat load and cooling costs.
Technical Highlights:
- N+1 Redundancy to 20kVA/18kW: Scalable design lets facilities grow capacity without replacing the base chassis — critical for phased data center buildouts where procurement and installation downtime are both expensive.
- 92% Efficiency: Reduces heat generation meaningfully compared to older double-conversion topologies — directly cuts cooling infrastructure requirements and operating costs in 24/7 environments.
- 208/120VAC 4-Wire Output: Native three-phase output on L-L-N-G wiring supports both 208V server feeds and 120V branch circuits from a single UPS — no additional distribution transformer needed.
Deployment Considerations:
- At 510 lbs and 38 inches tall, this unit requires a pre-installation structural floor assessment. Coordinate with your facilities engineer before scheduling delivery — retrofit raised-floor environments are frequently undersized for this weight class.
- The 40°C upper operating limit is adequate for conditioned data centers, but sustained ambient temperatures above 35°C will shorten battery and component life. If your server room runs hot during summer peak loads, address cooling before commissioning this unit.
This UPS is the right fit for mid-size enterprise data centers and colocation edge rooms where the load is expected to grow incrementally — the scalable N+1 architecture avoids a costly forklift upgrade when capacity needs expand beyond the initial 10kVA deployment.
