NCTS NU6K16S 6KVA/4.8KW Online Pure Sine Wave Tower UPS, 0ms Transfer, 192V Internal 16×12V 7Ah Battery, 120–275VAC Input & Smart Monitoring

EXPERT FEATURES 6KVA / 4.8KW Online UPS : Single-phase online UPS rated for 6KVA / 4.8KW output, designed for continuous protection of business, IT, networking and other critical electrical loads. Pure Sine Wave Output : Provides a sine-wave inverter output with THD below 3% on linear loads and below 8% on nonlinear loads. 0ms AC-to-Battery Transfer : Zero transfer time between AC and battery helps keep connected equipment powered without switching interruption. 0.8 Output Power Factor : Delivers up to 4.8KW real output power from its 6KVA capacity. Active Input PFC : The data sheet specifies active input power-factor correction with input power factor above 0.98. Wide Input Range : Supports a broad 120–275VAC input range and 45–55Hz input-frequency range for tougher grid conditions. Generator Compatible : NCTS specifically lists generator connectivity as a supported operating feature. Internal 192V Battery System : Uses sixteen internal 12V 7Ah batteries in a 192V battery group. Standard Backup Runtime : Rated for at least 10 minutes at half load and at least 5 minutes at full load under the stated standard configuration. Fast Battery Recovery : Standard charging reaches approximately 90% capacity in 5 hours. Bypass Overload Protection : At 105–125% overload, the unit transfers to bypass after 1 minute. Expandable Monitoring : RS232 communication can be converted to RS485, with dry-contact and smart-slot expansion supporting SNMP, SMS and other monitoring methods.
