The NCTS-NU3K6 is an online tower UPS designed to provide stable power for connected equipment during voltage fluctuations and power interruptions. It delivers a rated output capacity of 3KVA/2.7KW with single-phase input and output.
Moreover, the UPS uses a pure sine wave output and operates at a rated voltage of 220VAC. Its input voltage range extends from 115VAC to 300VAC ±5%, while the input frequency range is 45–55Hz ±0.5Hz. The bypass voltage range is 80–285VAC with the specified tolerance.
The NCTS-NU3K6 uses an internal 72V battery group. Its standard backup time reaches at least 10 minutes at half load and 5 minutes at full load. Furthermore, the batteries can charge to 90% in approximately five hours under the standard configuration.
In addition, the UPS provides 0ms transfer time between AC and battery operation. Its output voltage is regulated to 220VAC ±1%, while the output frequency reaches 50Hz ±1% during abnormal AC input conditions. The pure sine wave output has less than 3% THD with linear loads.
The unit supports RS232 communication, with options for RS485, dry contact, and a smart slot for expanded monitoring. It measures 460 × 192 × 333mm and weighs approximately 22.89kg net.
