Voltage stabilizer "Progress": field of application

Normal voltage is the usual household single-phase electrical network - 220V. At the same time, small deviations from the nominal value are permissible by 5% one and the other.

In other words, the voltage in the usual network for all ranges from 210V to 230V, and this is normal, since such fluctuations are not reflected negatively on the operation of household electrical appliances that are connected to a household electrical outlet. However, it is worth the effort to go beyond these permissible limits, as many devices will start to work incorrectly and may even completely fail.

In the event that the voltage was lower than normal, it is called reduced, and if it is higher, then increased. Both of these adversely affect electrical appliances, and with such jumps of tension, one must certainly fight without waiting for expensive equipment to fail and break down.

Models of stabilizers "Progress"

Voltage stabilizer "Progress" is produced by Energia LLC in Pskov. These devices are perfectly adapted to Russian household power networks. There are also domestic installations and special ones that are specially designed for interaction with high-precision equipment, which guarantees a voltage change in the network of no more than 1.5% in both directions.

For home needs, the voltage regulator "Progress" from the step-by-step series perfectly suits:

• T - series for use in normal conditions, which is designed to neutralize small voltage drops. It is controlled by a special autotransformer by switching its windings with special thyristor keys. There are single-phase - their power from 1 to 50 kVA - and three-phase, with a power of 9 to 150 kVA.
• The TR series is already a basic model, which has a wider amplitude of both working and limiting voltages. It is available for use in electrical networks where there are more significant voltage drops. They also switch between windings using thyristor switches. The modification for low voltage is above 100V and for high voltage up to 305V. Single-phase stabilizers with power from 3 to 12 kVA and three-phase with power from 9 to 36 kVA. The best in this series is the voltage regulator "Progress 8000".
• The L-series is a high-precision stabilization model, it features a fast response to voltage drops and a high overload threshold. In addition, it has a fairly wide range of operating and limiting voltages. Adjustment of the autotransformer is carried out with the help of a transformer, called a voltage-additive. Thyristor switches switch windings if necessary, as in the other models. Single-phase stabilizers with power from 3 to 50 kVA and three-phase from 9 to 150 kVA are produced.

The main distinguishing feature of all "Progress" voltage regulators is their completely silent operation, that's why they are perfectly suited for installation in rooms, which require high noise levels. So, they are often installed in residential apartments and private homes, where their work does not interfere with tenants. Those who installed the voltage regulator "Progress", reviews Leave the most positive, and most consumers are satisfied with his work.

For the convenience of the consumer, the stabilizers are available in a variety of designs: both for wall mounting and for floor installation.

Voltage stabilizers three-phase "Progress"

Before consumers, the question often arises of what to do if three phases are brought to the house, and not one. Is it possible to use a single-phase stabilizer in this case? The answer is unequivocal: "Yes." But only not for all household electricity. A conventional single-phase device can be installed only using one phase of the existing ones in the room. In this case, there is an option in which it is possible to install such stabilizers for each phase of the power grid.

Typically, a single-phase stabilizer is installed on the phase to which the most expensive and voltage-sensitive equipment is connected. The stability of its operation will depend on how correctly the load is distributed between the phases of the power grid. The load should be distributed approximately equally. Then they will perfectly cope with their functions and voltage regulators for the house "Progress".

Automatic control and rack units

Special racks, if equipped with a bypass, are used for the three-phase stabilizers of the Progress line, which are called Progress. Their power reaches 36 kVA. In addition, the delivery of automatic power supply control units - BCS is also possible.

BCS (network automatic control unit) with a power of 45 to 150 kVA is responsible for monitoring the network parameters in the case of three-phase connection. It controls all the load connected to it from all three phases. This unit is usually used to protect equipment that is particularly sensitive to voltage surges. Optionally, the network monitoring unit can be equipped with special "Work-By-Pass" switches to realize the operational shutdown of the "Progress" voltage regulator in order to pass current directly, bypassing the device. This is necessary in some cases to prevent power outages.

Characteristics of stabilizers "Progress"

1. The speed is greatly improved.
2. When overloaded, the shutdown occurs automatically.
3. Control is carried out by microprocessors.
4. The switching circuit is made on thyristors.
5. The presence of a series designed for operation at significant overloads (L).
6. The declared power is provided in the entire range.
7. Visual control on the LCD.
8. Control of the load and both the input and output voltage is fully automatic.
9. Switching off the power supply in case of exceeding the permissible values.
10. The output voltage is controlled in the range from 210V to 230V - the resolution is only 2V.
11. The efficiency of the stabilizer is more than 96%.

In fact, the voltage regulator "Progress" intended for operation in a three-phase network is equipped with three single-phase stabilizers. They are connected according to the "star" scheme.

The way of modular construction of three-phase stabilizers is more reliable, this structure is easier to transport, and its installation is much easier than using special three-phase stabilizers made in one housing.

terms of Use

• The temperature should not be below + 5 ° C and above + 40 ° C.
• Humidity of air up to 80% at + 25 ° С.
• UHL 4.2 - climatic performance.
• The environment should not be explosive, without conductive dust.

• Atmospheric pressure is up to 107 kPa.
• IP20 - protective class - unregistered.

Using a stabilizer with frequent power outages

Since the power outage is almost always accompanied by significant voltage drops, the voltage regulator will be very useful in this situation. It will help to protect the equipment connected to the network from breakage and, as a result, protect the owners from significant financial expenses for repair or purchase of a new one.

However, it should be borne in mind that the stabilizer can not serve as a source of electricity in the event of its shutdown. It only prevents the presence of unacceptably low or unacceptably high voltage in the network. To ensure that when power is cut off, there is still the possibility of using electrical appliances, you will have to buy a mini-power plant or an electric generator.

If such disconnections occur rarely and the period of lack of electricity is not too long, you can buy an uninterruptible power supply that will allow the technician to work after an overall power outage for an hour or two, depending on their total capacity.
