The characteristics of the models from the review can be found in the comparative table of interactive UPSs with pure sinusoidal output voltage. The entire range of “uninterruptible power supplies” is presented in the UPS section. And “How to choose a UPS” is described in the article of the same name.

The Marsriva MR-UF600P-H UPS is tasked with providing redundancy for the connected load and equalizing the mains voltage to power sensitive electronic equipment.

The model is made in the common Tower form factor and can be placed on any flat horizontal surfaces. In addition, you will need to connect an external battery with a voltage of 12 V. The battery capacity is selected individually according to specific user needs. This is discussed in more detail in the material “How to choose a battery for a UPS”.

This UPS can operate at a network voltage of 175 - 275 V and a current frequency of 45 - 65 Hz. If these limits are violated, the connected load is transferred to power from the battery. “Bespereboynik” effectively smoothes out fluctuations in mains voltage, and during power outages it switches to battery operation in about 6 ms. The Marsriva MR-UF600P-H provides the stable sine wave output signal required by sensitive electronic devices.

The model is supposed to be loaded with a total connection power of up to 360 W in nominal operating mode. The highest apparent load power allowed by a UPS is 600 W on a short-term basis. As for the interface connectors, the UPS is equipped with one Schuko socket, and there is a built-in info screen to visualize the device’s operating parameters.

The linear-interactive uninterruptible power supply RITAR RTSW-600NL12 is designed to work together with external 12-volt batteries and is supplied without a battery included. It is assumed that the user will independently select a battery for the UPS, focusing on his own needs.

As already mentioned, the model belongs to the segment of “uninterruptible power supply” interactive type. Those. it not only functions as a backup power source, but also serves as a stabilizer - the UPS smoothes out voltage surges and sags in the range from 160 to 275 V. When the specified limits are exceeded, the operation of the connected equipment automatically switches to battery power. The device also provides noise filtering.

RITAR RTSW-600NL12 produces pure sinusoidal voltage of the correct shape. Such nutrition is absolutely necessary for sensitive equipment. The control electronics of a heating boiler, delicate computer equipment, etc. can be backed up from the UPS. The total power of the load connected to the uninterruptible power supply should not exceed 360 W in nominal operating mode and 600 W during peak power surges.

The UPS can be operated in a temperature range from 0 °C to +45 °C. The model has only one output connector - a standard F-type socket (Schuko). Additional assets of the UPS include a protection system against overloads and short circuits, which is responsible for the trouble-free operation of the device.

2E 2E-PS500L is a fairly advanced line-interactive UPS with a mains voltage stabilization function and an output signal in the form of a flat sine wave.

The model is supplied without a built-in battery, instead an external battery with a voltage of 12 V is used. The user must purchase an additional battery separately for the expected backup time of the connected load. The output connectors on board the UPS are represented by two Schuko sockets, one C13/C14 socket and a LAN interface - the UPS can be used to protect the data transmission line.

The device is designed to work with loads with a total power of up to 300 W. The UPS handles peak power surges at levels up to 500 W. From the settings here , you can select the output voltage (220/230/240 V) and finely adjust the charging current for the battery (ranging from 1 to 10 A). You can control all of these parameters using the data on the info screen. Error codes are also displayed on the display when failures occur.

The additional package of the UPS includes USB and RJ45 switching interfaces, which are used to control the operation of the device. The device also provides the possibility of a “cold start” - turning on equipment connected to the UPS when there is no voltage in the network. The only thing that upsets the 2E 2E-PS500L is its large dimensions (215x144x345 mm) and its considerable weight (about 7 kg). However, this is not a category of equipment that needs to be constantly moved from place to place. So you can safely close your eyes to this nuance.

An important share of profit for the Polish company Volt Polska comes from uninterruptible power supplies. One of these is the balanced interactive model Sinus PRO 500E.

The device is intended for use with 12 V batteries. The UPS is supplied without its own battery. “Uninterruptible power supply” is used to stabilize the mains voltage, and if there is no current in the outlet, it automatically switches the load to power from the battery (in about 4 ms). At the output of Volt Polska Sinus PRO 500E you can get a voltage of 230 V with a frequency of 50 Hz.

An important characteristic of the model is the output signal in the form of a flat sinusoid. It ensures proper operation of power tools, refrigerators, air conditioners, and central heating systems. In general, any load that places high demands on voltage quality. To control the input and output parameters, the UPS was equipped with an info screen. It also displays indicators of problems in the operation of the uninterruptible power supply.

In long-term operation, the device pulls a total load of up to 300 W, in the short term it can withstand power surges of up to 500 W. The rear panel of the UPS case has two sockets for connecting consumers. There you can also see the fan of the cooling system of the “internals” (and quite noisy). In addition, the model was equipped with a handle for easy carrying of the 3.9-kilogram case.

Uninterruptible power supplies and voltage stabilizers form the backbone of the products of the Ukrainian brand Logicpower. The advantages of both of these types of devices are harmoniously combined in the LPA-W-PSW-500VA model.

The device in question is used to stabilize voltage in electrical networks and back up the connected load during power outages. The UPS input can be supplied with voltage from 140 to 275 V. Outside the specified values, the operation of the uninterruptible power supply is automatically switched to power from the battery. By the way, the model is not equipped with a battery - a 12-volt battery of the required capacity is supposed to be purchased separately.

Logicpower LPA-W-PSW-500VA is equipped with one type F socket (Schuko), which is used to connect a rated load of up to 350 W. The pure sine wave output allows the UPS to be used to power sensitive electronics. The model is optimally suited for working with heating and water supply systems. In terms of placement options, it can be hung on a wall or installed on any flat horizontal surface (for this purpose, there are legs in the lower part of the case).

An LCD information screen is used to display the operating parameters of the UPS online. The model also impresses with the quiet operation of the on-board cooling system (within 40 dB) and the “cold start” option for connected equipment. The load can be started even in the absence of mains voltage. The picture is complemented by multi-level protection against short circuits, power surges, overloads, too deep discharge or overcharging of the battery.
