FOCUS UPS 850VA: Essential Power Protection for Your Electronics
The FOCUS UPS 850VA is a compact and reliable uninterruptible power supply designed to safeguard your valuable electronic equipment from power outages, surges, and voltage fluctuations. With a sensible power capacity and built-in voltage stabilization, it provides a crucial layer of protection for desktop computers, networking gear, and home office setups. This UPS is an ideal choice for users who need a dependable backup power source and clean, consistent electricity to prevent data loss and hardware damage.
Power Capacity and Type
The FOCUS UPS 850VA UPS delivers a practical amount of power, making it suitable for a home workstation.
- VA Rating: 850VA (Volt-Amperes), which represents the total apparent power the unit can handle.
- Wattage (W) Rating: The typical wattage rating for an 850VA UPS is 480W. This is the true power that the unit can deliver to connected devices, calculated with a power factor of 0.6.
- Topology: It is a Line-Interactive UPS, which means it has built-in Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, thus preserving the battery for true outages.
- Waveform: The UPS provides a Simulated Sinewave output on battery power, which is suitable for most desktop PCs, monitors, and peripherals.
Output and Connectivity
The FOCUS UPS 850VA UPS is equipped with multiple outlets and protections to connect your essential devices.
- Outlets: It typically features 4 to 8 universal power outlets, allowing you to connect a wide range of devices. Some models may have a split configuration, with half the outlets providing both surge and battery backup, and the other half offering surge protection only.
- Surge Protection: All outlets offer surge and spike protection to guard against dangerous voltage events that can damage sensitive electronics.
- Input: The UPS connects to the wall outlet via a standard power cord.
- Data Protection: It often includes ports for RJ11/RJ45 (phone line or Ethernet) protection to safeguard against power surges traveling through data lines.
Battery and Runtime
The FOCUS UPS 850VA internal batteries provide sufficient backup time for a safe shutdown.
- Battery Type: The unit is equipped with a single 12V/7.2Ah sealed lead-acid battery.
- Runtime: The runtime varies depending on the load. At a typical load of 200W, the UPS can provide approximately 8 to 12 minutes of backup power, giving you ample time to save your work and safely shut down your systems. At a full load of 480W, the runtime is typically around 2-3 minutes.
- Recharge Time: The batteries take approximately 6 to 8 hours to fully recharge to 90% capacity after a complete discharge.
Design and Features
The FOCUS UPS 850VA UPS features a practical design and a set of useful functionalities.
- Form Factor: It comes in a tower-style desktop form factor.
- Display: It has a clear LED or LCD screen that provides real-time information on the UPS status, including input/output voltage, battery charge level, and load percentage.
- Automatic Voltage Regulation (AVR): The AVR function automatically stabilizes the output voltage, preventing the UPS from needlessly switching to battery power during brownouts or sags.
- Safety Features: Includes protection against overload, short circuits, and over-discharge of the battery.
- Software: The UPS may come with management software that allows you to monitor its status, schedule shutdowns, and receive alerts from your connected computer via a USB cable.
