The best backup UPSs

Powercom WOW-850U

Not too large, but quite functional device. It has a rectangular body with a streamlined shape, all corners are rounded. At the top of the product there is a mechanical button to turn the product on, and there are also three LED-based indicators. There are also three Euro type sockets. They are equipped with a special protective mechanism that prevents various types of foreign objects from getting inside. The body is made of matte molded plastic. The casting quality is excellent, the assembly is also very good, so there are no backlashes or extraneous creaks. All ventilation holes are located on the sides of the device. The legs are plastic, there are special holes for mounting in the wall.

All connectors for connecting communication equipment, including a USB port, are located on one of the sides. A non-switchable power wire and an automatic fuse come out of the end part. This device contains a WP1213W battery, the capacity of which is 13 Wh, its operating voltage is 12 V. The internal elements are located quite compactly. All electronic parts of the design are located on a double-sided printed circuit board, which is located at the bottom of the case. The inverter operates on two transistors assembled using a high-frequency circuit. Power transistors are installed on large radiators. There is no automatic voltage regulator provided here. The UPS switches to battery power when the input voltage is less than 165 V, and before this it emits a corresponding sound signal. If the battery is almost discharged, the signal frequency increases and is 1 time per 0.4 seconds.

Advantages:

• Reasonable cost;
• Small overall dimensions;
• Protection of sockets from accidental objects;
• It works silently.

Flaws:

• In offline mode it is not able to work for too long, but it is quite enough for the correct shutdown of the equipment.

Which UPS is better to buy?

To choose the most suitable UPS, you should decide on the initial data: the quality of the current in the electrical network used, the number and type of devices that will be connected to the UPS, the expected cost of the device, etc.

All uninterruptible power supplies are divided into:

• reserve;
• interactive;
• inverter

A backup UPS will be a good solution when power surges are rare and only 1-2 devices need protection. When purchasing such a device to protect a PC, you need to check the compliance of the minimum and maximum voltage values ​​of the device and the consumer in order to prevent unnecessary UPS operations in situations where the connected device can still work.

If the network is unstable, the voltage drops to 180-190 V, and a large number of devices need to ensure uninterrupted operation, it is better to use an interactive UPS. It has full functionality of backup devices and, in addition, allows you to regulate the voltage at the network output. A device of this type essentially consists of a backup UPS and a stabilizer.

The best quality power supply can be obtained using inverter (on-line) UPSs, the battery of which is constantly connected to the network. Due to this, any voltage dips during transitions to autonomous mode are excluded.

The most important technical characteristics that can influence the choice of UPS are:

• Output power, which determines the total power of all consumers connected to the device.
• Battery life - the higher this indicator, the more time the user has to, for example, shut down work on the computer without losing data.
• Type of output connectors - these can be sockets of the older IEC-320-C14 type or the Euro standard CEE 7/4.
• Control interface – USB, LAN, RS-232, SmartSlot.

Equipping with additional functions also plays an important role. These include:

• Possibility of voltage adjustment;
• Cold start;
• Connecting an external battery;
• Bypass (direct connection);
• Display, etc.

Based on the installation method, UPSs are divided into conventional (floor-standing), wall-mounted, and server (rack-mounted). For some consumers, an important parameter is the voltage shape at the output of the device, which can be sinusoidal or stepped.
