NCTS QSTROM 2000VA Line-Interactive UPS With Two 12V 9Ah Batteries, AVR, LCD Monitoring, Cold Start, Generator Support and Simulated Sinewave Output

Expert Features

• 2000VA Line-Interactive Capacity: Built for desktop computers, office equipment, networking devices, and other compatible electronics that need short-term backup power and automatic voltage support during unstable mains conditions.
• Automatic Voltage Regulation: Two boost stages and one buck stage help stabilize a wide input range without immediately switching to battery power, reducing unnecessary battery cycling during common voltage fluctuations.
• Wide Input Voltage Range: Supports 81–145VAC or 162–290VAC, allowing the UPS to continue regulating power across unusually low or high mains-voltage conditions.
• Fast Transfer Response: Typical 2–6ms transfer time, with a stated 10ms maximum, helps reduce interruption when switching from utility power to battery mode.
• Simulated Sinewave Output: Delivers a simulated sinewave while operating on battery, suitable for many conventional PC, office, and networking loads; compatibility should be checked for highly sensitive active-PFC or specialized equipment.
• Dual-Battery System: Uses two 12V 9Ah batteries in a 24VDC configuration, providing the energy reserve needed for supported equipment during outages.
• Off-Mode Charging: The battery can recharge while the UPS output is switched off, helping restore battery capacity without actively powering connected equipment.
• Intelligent Battery Recharging: The built-in charging system is designed to recover the battery to approximately 90% capacity within 6–8 hours under typical conditions.
• Cold-Start Function: Allows the UPS to start from battery power without an available AC supply, useful when equipment must be powered during a complete outage.
• Generator Compatibility: Designed to operate with compatible generator sources, making it more flexible for locations that rely on backup generation.
• Informative LCD Monitoring: The LCD version displays operating mode, load level, battery level, input voltage, output voltage, overload, fault, and low-battery conditions for quick status checking.
• Comprehensive Protection: Includes short-circuit, overload, overcharge, and battery over-discharge protection to help protect the UPS and attached compatible equipment.
• Audible Status Alerts: Distinct alarm intervals indicate battery operation, low battery, overload, battery-replacement warning, and system faults.
• Compact Tower Design: The 380 × 158 × 198mm housing and approximately 10.5kg net weight provide substantial backup hardware in a relatively compact floor or desk-side footprint.
