When downtime isn't an option, the NCTS NU6K16S delivers. This single-phase online UPS rated at 6KVA / 4.8KW is engineered for continuous, rock-solid protection of business, IT, networking, and other critical electrical loads. From servers and data rooms to telecom gear and industrial controls, this tower UPS keeps everything running—even when the grid doesn't.
True online double-conversion design means your equipment always runs on clean, inverter-generated power—not raw utility power. Combined with a 0ms AC-to-battery transfer, connected devices never see a switching interruption. That's the kind of protection that saves hard drives, prevents data loss, and keeps business operations flowing.
Pure sine wave output with THD below 3% on linear loads (and below 8% on nonlinear loads) ensures sensitive electronics receive the cleanest possible power. A 0.8 output power factor lets you draw the full 4.8KW of real power from the 6KVA capacity—no surprises when you're sizing your load.
⚡ Built for tough grids: A wide 120–275VAC input range and 45–55Hz frequency window mean the UPS tolerates unstable voltage and frequency swings. Active input PFC (power factor above 0.98) improves efficiency and reduces strain on your electrical infrastructure. And because it's generator compatible, you can pair it with backup generation for layered resilience.
🔋 Internal 192V battery system: Sixteen internal 12V 7Ah batteries deliver ≥10 minutes at half load and ≥5 minutes at full load in standard configuration—enough time to ride out short outages or safely shut down critical systems. Standard charging recovers to ~90% capacity in just 5 hours, so you're ready for the next event.
📦 Expandable monitoring: RS232 communication can be converted to RS485, while dry-contact and smart-slot expansion support SNMP, SMS, and other monitoring methods. Integrate it into your UPS systems fleet and manage it your way.
