Best Uninterruptible Power Supplies

This UPS has a high power output compared to other modifications, 1500VA/900W. Such index will give you up to 3 minutes of a wireless productivity at a full runtime and up to 11 minutes at a half runtime. It will be enough to properly shut down the computer and save the important information or just prevent a hard shutdown of your electronic equipment. The CyberPower UPS will need 4 milliseconds to transfer to a battery backup. There are 2 easily replaced 12V / 8.5Ah lead-acid batteries with time-efficient 8-hour charging.

The main task of the CyberPower UPS is to protect your electronics from an excess voltage. It diverts the overvoltage away during a power surge or AC current spike, to prevent your sensitive electronic equipment from damaging. It also protects the data line from power surges traveling via telephone, coaxial, and Ethernet, to secure the connected devices. The manufacturer provides a convenient dashboard interface (PowerPanel® Personal Edition Software). You can connect the USP to your PC with a USB cable to control and monitor the power supply device. It also saves all the important data.

This extra modern device features a patented GreenPower UPS™ design that lets the power supply bypass the UPS transformer if AC power is stable. It helps to reduce the heat buildup, noise, and energy consumption. An automatic voltage regulation provides clean and nonstop AC power supply by means of low and high voltage regulation. A large LCD display will let you monitor the battery backup and power conditions to discover potential problems before they damage your electronics.

Now, let's take a closer look at the display. Thanks to the handy icons it shows, it is easy to monitor the device's performance. For example, if conditioned AC power is supplied to your equipment, you will see a plug in the upper left corner of the screen. To its right, there are icons to display the item's load capacity and its battery charge level. The unit will show the number of events that occurred; special signs will appear when the unit is compensating for low voltage or it is providing a battery backup.

To get an excess to additional data and settings, you can download a PowerChute software; a cable to connect your PC to the unit's USB port is included in the box. On the back panel of the UPS, in addition to the outlets and a USB port, you will find surge-protected In/Out Ethernet and Coaxial ports.

Despite being that functional, the appliance is very simple to operate. There are only three buttons on its front panel:

• A Mute button will allow you to turn the audio alarms on and off.
• A Power On/Off button will help you activate the unit so that it receives the input AC power; in case the latter is not available, it will use the battery power. If you hold the button for two seconds, the device will not receive the input AC power; it will only provide surge protection.
• A Display button will help you get the desired information on the UPS performance; it will also allow you to switch the unit to a power-saving mode (in this mode, the LCD will light up when you press the button and darken after 60 seconds).

The 600VА/330W power output of this APC UPS will guarantee a high protection of your home or office energy-efficient computer. The wireless operation of this UPS is 4 minutes (at the maximum battery backup load) and 10 minutes (at an average load). You can shut down your PC properly and save all the important information if a power failure occurs. This UPS power supply switches to a battery backup in about 8 ms. The device features a maintenance-free sealed lead-acid battery with a suspended electrolyte, meaning it is leak-proof. It has 10-hour charging time.

This APC back-UPS effectively protects your household electronics and all other devices connected to a data line with a DSL (RJ–11 connector), Network – 10/100, Base–T Ethernet (RJ–45 connector). And this efficient UPS has one more useful option — an automatic battery self-test, that will detect early if the battery needs to be replaced. This feature will help you maximize battery's useful life through accurate charging.

Using a battery condition test, the APC BE550G provides an early battery failure notification to enable preventive maintenance on time. The device has 7 NEMA 5-15R outlets and USB charging port. Four of them are intended for battery backup and surge protection, to ensure your hardware and data safety during power outages and surges. Four other are surge-only outlets; they protect secondary electronics. This APC UPS has an adjustable voltage sensitivity to assure an excellent performance of this UPS with any power supply, including battery backup. An audible alarm will warn you of changes in a power network and UPS power conditions.

With its 1500VA/900W capacity, the Tripp Lite SMART1300 UPS is one of the most powerful devices in this class. It assures a 10 minutes power supply to your electronics in case of a sudden power feed cut-off. You will shut down your computer properly and save all the essential data. A switch to the backup supply takes about three milliseconds. The Tripp Lite UPS battery backup has a set of two replaceable batteries with 8 hours of battery charging time.

This USP is a wonderful device providing a high-efficiency power surge and burst protection. Besides, the Tripp Lite SMART prevents the disruptive line noise for an effective telephone, coaxial and Ethernet line protection for the devices connected to this USP. In addition, the manufacturer provides a free PowerAlert software for an advanced protection, such as automatic data saving, events notification, devices monitoring. An SNMP supports the centralized management.

A multifunctional LCD display enables an easy access to the detailed UPS settings and power conditions control. You will be able to monitor an input/output voltage and frequency, battery voltage, load/charge level meters, output load percentage and wattage, power, battery, AVR status and battery backup runtime. You can also control your USP using the HID-compliant USB port and your PC's built-in power management features. In case of frequent power surges, the UPS will switch to the battery backup which may cause a power decrease and battery's service life shortening. An automatic voltage regulation will indicate if the input voltage is beyond the limits and correct it without any battery backup. In addition, the Tripp Lite USP provides an efficient filtration of a line noise.

An 825VA/450W capacity is quite enough to provide an uninterruptible power supply to a few electronic devices. The wireless battery backup will last for 2 minutes at the peak load conditions, and 8 minutes at a half load. This is enough time for a proper shutting down of your computer in case of an AC power failure. This will help you prevent data loss and any damage to your sensitive electronics caused by a sudden shutdown. The CyberPower UPS will switch to a battery backup in 4 ms. The sealed lead-acid replaceable battery needs 8 hours to charge.

The CyberPower UPS provides an effective power surge and a power strike protection for your sensitive electronic equipment. It will also prevent the damage of your electrical devices from power surges that may travel via coaxial, telephone and Ethernet lines. The PowerPanel® software comes with the purchase. Thus, a convenient dashboard interface will let you easily control and monitor your UPS performance.

This up-to-date portable CyberPower UPS features an ultra-quiet design minimizing noise during the operation. A multifunction LCD panel displays a detailed information on the battery backup and power conditions to alert you in case there's a chance of potential problems damaging your electronic equipment. The UPS is equipped with an AVR, automatically regulating low- and over-voltages. An audio beep signal will warn you to timely recharge the battery when it runs flat. The UPS has eight NEMA 5-15R outlets: 4 for a surge protection, 4 for a surge protection + battery backup.
