The KSTAR 2000VA Offline UPS is a reliable and robust Uninterruptible Power Supply solution, designed to provide essential power backup and surge protection for a variety of electronic equipment, including desktop PCs, networking gear, and small office systems. With a high capacity of 2000VA and a substantial 1200W load capacity, this unit is well-suited for setups requiring a significant power buffer. It operates as an offline (or standby) UPS, which means it instantly switches to battery power within a quick 4–8 milliseconds when the main power fails or fluctuates outside its safe range. This rapid transfer time is crucial for preventing interruptions, data loss, or damage to sensitive devices. The UPS is built to handle an impressively wide input voltage range, typically from 140V to 300V, while maintaining a stable output of 230V for connected equipment. During an outage, it provides a backup time that ranges from 7 to 20 minutes at full load, offering ample time to safely save files and shut down systems. Compact in design (dimensions around 380×158×198 mm), the KSTAR 2000VA operates with a low noise level (less than 45 dB), making it suitable for office and home environments. It offers protection against overloads and short circuits, ensuring the longevity of both the UPS and connected devices. This model is an excellent choice for users seeking dependable, high-capacity power assurance against power irregularities.
Features of KSTAR 2000VA Offline UPS
Capacity: 2000 VA (Volt-Amperes)
Load Capacity: 1200 W (Watts)
Topology: Offline/Standby UPS (switches to battery power during outages/fluctuations).
Backup Time: 7 – 20 minutes (at full load, the exact time depends on the connected load).
Transfer Time: Fast transfer rate of 4 – 8 ms (milliseconds) to minimize disruption.
Protection Features: Includes Overload Protection, Short Circuit Protection, and intelligent battery discharging/charging management.
Automatic Voltage Regulation (AVR): Often features built-in AVR functionality to stabilize output voltage and protect connected devices from fluctuations (though some listings suggest this is an optional line-interactive feature, the wide input range indicates some form of voltage regulation).
Input Voltage Range: Wide range of 140–300 V (Volts).
Output Voltage: Consistent 230 V.
Waveform: Sine Wave (on mains/AC mode) and Square Wave or Simulated Sine Wave (on battery/inverter mode).
Noise Level: Low noise operation, typically less than 45 dB.
Cold Start Function: Ability to start the UPS on battery power without an AC utility connection.
Indicators/Display: Uses LED indicators (and sometimes an optional LCD display) for operational status (Line Mode, Battery Mode, Error, etc.).
Physical: Compact dimensions, often around 380×158×198 mm.
Communication: May include an optional USB communication interface for remote monitoring and management (depending on the specific model variation).
