Vertiv AS3C0NCWGNNXLKB 15KVA N+1 Scalable 3-Phase UPS
Overview
The Vertiv AS3C0NCWGNNXLKB is a rack-mounted, scalable UPS rated at up to 15kVA/13.5kW with built-in N+1 redundancy — the right call for data centers, network closets, and critical infrastructure environments where a single power module failure cannot take the load offline. At 42U tall and 795 lbs, this is purpose-built for high-density power protection in permanent installations, not for easy relocations. The 208VAC input with 208/120VAC output covers the standard split-phase distribution topology common in US commercial buildings, and the 3-Wire (L-L-G) wiring configuration means it drops straight into most existing commercial electrical panels without a neutral run.
If you're sizing Vertiv power protection for a mid-to-large surveillance or IT deployment, the AS3C0NCWGNNXLKB sits in the scalable UPS category designed to grow with load demands rather than force a full equipment swap when capacity needs increase.
Key Features
- 15kVA/13.5kW N+1 Power Rating: N+1 redundancy means one power module can fail completely and the full rated load stays online without interruption. For a 24/7 surveillance recording environment or a live network operations center, that's the difference between a planned maintenance window and an unplanned outage. The 15kVA/13.5kW ceiling gives you real headroom for high-draw equipment racks without derating concerns on day one.
- 208VAC Input / 208-120VAC Output: Accepts standard 208VAC single-phase commercial input — no step-up transformer required in typical US commercial buildings. The dual-voltage output (208V and 120V) lets you power both high-draw servers and switches on 208V circuits and standard 120V peripherals from a single UPS, eliminating the need for separate downstream distribution units in many configurations.
- Up to 92% Efficiency: At 92% efficiency, losses translate to roughly 1.2kW of heat generation at full 13.5kW load. In a dense server or network switch environment, that's a meaningful HVAC load reduction compared to older transformer-based UPS designs running at 85-88%. Over a multi-year deployment, the difference compounds in both energy cost and cooling infrastructure sizing.
- 3-Wire (L-L-G) Wiring: The L-L-G wiring scheme is compatible with standard US commercial 208V distribution without requiring a neutral conductor. That matters in retrofit installations where existing conduit runs were sized for 3-wire and adding a neutral would require re-pulling wire or upsizing conduit — a significant labor and cost consideration in finished data center or telecom spaces.
- Operating Temperature 0°C – 40°C (32°F – 104°F): The 40°C upper limit is adequate for most air-conditioned equipment rooms, but worth checking against your HVAC setpoint plus ambient rise in a high-density rack environment. If your room runs hot under load — say, 38°C ambient in summer — you're within 2°C of the ceiling, and that's a derating conversation to have before commissioning.
