Vertiv AS5C0NCWGNNXLKB 15KVA Modular Uninterruptible Power Supply
Overview
The Vertiv AS5C0NCWGNNXLKB is a 15kVA/13.5kW N+1 modular uninterruptible power supply built for commercial and enterprise environments where power continuity is non-negotiable. Designed around a 208/120VAC four-wire topology, it sits cleanly into mid-scale data closets, security control rooms, and network equipment racks without requiring a dedicated power distribution overhaul. The AS5C0NCWGNNXLKB ships as part of the Vertiv power protection line and is a strong match for integrators commissioning always-on infrastructure — NVR arrays, access control head-ends, managed switch stacks, and server rooms where even brief outages translate to real operational cost. At 565 lbs and a 17 × 27 × 32-inch footprint, this is a floor-standing unit; plan floor loading and cable routing before the delivery truck arrives.
Key Features
- 15kVA / 13.5kW N+1 Power Rating: The N+1 architecture means one redundant power module is always standing by. If an active module fails mid-shift, the system keeps running without a technician touch — critical in unmanned equipment rooms or 24/7 surveillance installations where a full UPS failure would take down every camera and recorder simultaneously.
- 208/120VAC Input and Output: Dual-voltage support on both input and output eliminates the need for step-down transformers or separate distribution panels when your load mix includes both 120V edge devices (PoE switches, small servers) and 208V draw equipment (larger NVRs, rack PDUs). The four-wire L-L-N-G wiring scheme aligns with standard commercial electrical panels — no specialty wiring required if your building is already on three-phase or split-phase 208V.
- Up to 92% Efficiency: At rated load, 92% efficiency keeps heat output and operating costs in check. For a power protection unit running continuously, the difference between 85% and 92% efficiency can translate to hundreds of dollars annually in electricity savings and measurably lower cooling demand in a sealed equipment room.
- Modular Architecture (N+1 Redundancy): The modular design means capacity or redundancy can be scaled without replacing the entire chassis. Adding or swapping modules in a live system reduces downtime risk compared to monolithic UPS designs, and it gives facilities teams a staged upgrade path as connected load grows over time.
- 0°C to 40°C Operating Temperature Range: The 32°F–104°F operating envelope covers standard conditioned equipment rooms and most climate-controlled server closets. It is not rated for outdoor or unconditioned industrial environments — keep ambient temperature managed if this unit is in a telecom closet without dedicated HVAC.
- 565 lb Weight with 17 × 27 × 32-Inch Footprint: At over a quarter ton, structural floor capacity must be verified before installation. The 17-inch width aligns with a standard 19-inch equipment bay when accounting for side clearances, while the 32-inch depth requires adequate front and rear access — account for cable management trays and battery module extraction paths in your floor plan.
Integration and Compatibility
The AS5C0NCWGNNXLKB operates on a 208/120VAC four-wire (L-L-N-G) circuit, which is standard in commercial office buildings, data centers, and security operations centers running North American electrical infrastructure. The dual-voltage output supports mixed downstream loads, making it practical for network switches, NVRs, servers, and access control panels sharing the same protected distribution. Consult your electrical contractor to confirm panel ampacity and breaker sizing before commissioning — a 15kW load at full draw demands appropriately sized upstream protection. For facilities planning a phased build-out, the N+1 modular design allows load expansion without full system replacement, which reduces lifecycle capital expenditure on power infrastructure. Pair this unit with a compatible rack PDU to distribute protected 208/120V output cleanly across your equipment rack. Review Vertiv's monitoring and management ecosystem to determine whether SNMP or dry-contact integration with your BMS or VMS platform requires additional interface cards.
Frequently Asked Questions
Q: What is the maximum power output of the AS5C0NCWGNNXLKB?
A: The AS5C0NCWGNNXLKB delivers up to 15kVA / 13.5kW in an N+1 redundant configuration, meaning one module is held in reserve to cover an active module failure without interrupting the connected load.
Q: What input and output voltages does the AS5C0NCWGNNXLKB support?
A: Both input and output are rated at 208/120VAC using a four-wire (L-L-N-G) wiring scheme, compatible with standard commercial split-phase and three-phase electrical panels in North America.
Q: How efficient is the AS5C0NCWGNNXLKB under load?
A: Vertiv rates the unit at up to 92% efficiency, which reduces heat generation and operating costs compared to older UPS designs that typically run in the 80–88% range.
Q: What are the physical installation requirements for the AS5C0NCWGNNXLKB?
A: The unit weighs 565 lbs and measures 17 inches wide × 27 inches tall × 32 inches deep. Floor structural capacity must be verified before installation. The operating temperature must be maintained between 0°C and 40°C (32°F–104°F), so an unconditioned or outdoor location is not suitable.
Q: Can the AS5C0NCWGNNXLKB support both 120V and 208V equipment simultaneously?
A: Yes. The 208/120VAC dual-voltage output allows mixed downstream loads — for example, 120V PoE switches and 208V rack-mounted servers or NVRs — on the same protected distribution without additional step-down transformers.
Q: What does the N+1 designation mean for the AS5C0NCWGNNXLKB?
A: N+1 means the system includes one more power module than the minimum required to carry the rated load. If any single active module fails, the redundant module takes over automatically, maintaining uninterrupted power to connected equipment.
The AS5C0NCWGNNXLKB is a unit I'd specify with confidence for mid-scale security operations centers or network equipment rooms where you're running mixed 120V and 208V loads and can't afford a single-module failure to take the whole site dark. The 15kVA/13.5kW N+1 rating gives you real headroom — not just rated capacity, but a live spare module that kicks in automatically without any manual intervention or scheduled maintenance window.
Technical Highlights:
- 92% Efficiency: At 15kW continuous draw, the difference between 85% and 92% efficiency is roughly 1kW of heat you're not pumping into the equipment room — that's real money on cooling and electricity over a multi-year deployment lifecycle.
- 208/120VAC Dual Voltage: The four-wire L-L-N-G output lets you feed both 120V edge devices and 208V high-draw equipment from a single protected source, which simplifies distribution design and reduces the panel real estate needed for separate circuits.
- N+1 Modular Architecture: Unlike a monolithic UPS where any internal failure risks full shutdown, the modular design isolates faults to individual modules — and lets you hot-swap or expand capacity without decommissioning the system.
Deployment Considerations:
- At 565 lbs, floor load capacity is the first thing to verify — standard raised-floor data center tiles are typically rated 1,000–2,000 lbs per tile, but non-raised commercial floors in repurposed office space often are not. Get a structural sign-off before the unit ships.
- The 0°C–40°C operating limit means this unit requires a conditioned environment. A telecom closet with intermittent HVAC is a risk — if ambient temperature spikes during a summer heat event or HVAC failure, you'll need thermal monitoring in place to alarm before you hit the limit.
For a security integrator commissioning a 20–50 camera deployment with redundant NVRs, managed PoE switches, and an access control head-end all on one protected bus, the AS5C0NCWGNNXLKB hits the right capacity tier and the N+1 redundancy makes it defensible in any SLA conversation with the end customer.
