The GXK-850-C is an 800VA / 480W Line Interactive UPS designed to provide reliable backup power and protection for computers, networking devices, CCTV systems, POS equipment, office electronics, and other essential devices.
Featuring AVR voltage stabilization, simulated sinewave output, microprocessor control, automatic restart, and cold start functionality, the GXK-850-C helps protect connected equipment from power fluctuations, outages, overloads, and other common electrical problems.
The GXK-850-C uses advanced microprocessor-controlled technology with an internal self-diagnostic function to improve reliability and continuously monitor the UPS operating conditions.
Its Line Interactive design allows the UPS to regulate unstable mains voltage without unnecessarily switching to battery power, helping extend battery life and maintain reliable operation.
The UPS supports a wide 140–300VAC input voltage range, making it suitable for locations where mains voltage frequently fluctuates.
Its built-in Boost and Buck AVR automatically adjusts the input voltage:
This helps provide a more stable power supply to connected equipment while reducing unnecessary battery usage.
The automatic restart function allows the UPS to restart automatically when AC mains power is restored after an outage.
The cold start function allows the UPS to start from battery power when mains electricity is unavailable, provided that the battery has sufficient charge.
This makes the GXK-850-C a practical backup solution for locations with frequent power interruptions.
When operating in battery mode, the GXK-850-C produces a simulated sinewave output with a frequency of 50/60Hz ±1Hz.
This waveform is suitable for many common electronic and office devices. For equipment that specifically requires a pure sinewave output, a pure sinewave UPS is recommended.
The GXK-850-C provides a typical transfer time of approximately 4–8 milliseconds, with a maximum specified transfer time of 13 milliseconds.
The fast transition between mains and battery operation helps minimize interruptions to connected equipment during a power failure.
The GXK-850-C uses a 12V 9Ah rechargeable battery.
The typical recharge time is approximately 6–8 hours to recover 90% battery capacity, depending on battery condition and operating conditions.
The UPS also includes battery protection against overcharge and overdischarge.
Depending on the selected version, the GXK-850-C can be equipped with either an LED display or LCD display.
The LED version indicates:
The LCD version provides more detailed operating information, including:
This allows users to quickly monitor the UPS status and identify potential problems.
The GXK-850-C provides full protection against common electrical and battery-related conditions, including:
These protection features help reduce the risk of damage to both the UPS and connected equipment.
The UPS uses different alarm patterns to clearly indicate its operating condition:
This makes it easier for users to identify warnings without constantly checking the display.
The GXK-850-C supports USB or RS232 communication, allowing the UPS to communicate with a connected computer for monitoring and management.
It supports a wide range of operating systems, including:
This communication capability makes the UPS suitable for computer and IT environments where UPS monitoring is required.
With dimensions of approximately 314 × 130 × 175 mm and a net weight of approximately 4.9 kg, the GXK-850-C has a compact footprint that can easily fit on or under a desk, in an office environment, or alongside networking equipment.
Its noise level is less than 45dB, helping maintain a relatively quiet working environment.
