In some cases, the capacitors overheat. The rated voltage of the meter is 230 V. The deviation factor is relatively low. You should also consider the high cost of the goods. The price for this meter fluctuates around 3600 rubles.
The specified counter refers to one-tariffmodels. The threshold sensitivity parameter of the modification is 0.3 A. In this case, the accuracy class is only of the third degree. Some buyers complain about the complex installation of the device. Adapters on two terminals for the model are not suitable.
Condensers overheat quite often. It is also important to note that this model should often be worn for verification. The nominal frequency of the device is 58 Hz. On this electricity meter (single-phase) the price fluctuates around 2800 r.
This counter belongs to two-tariff models. Among the advantages of the device is its compactness. In this case, the resistors are of a through type. Thus, with the accuracy of measurements, problems are rare. In the installation, the device is quite simple and convenient. Adapter for three terminals for the model is suitable. In this case, the instrument reading is clearly visible. The atmospheric pressure of the device is 90 mm Hg. Art. If you believe consumer reviews, then problems with failures are rare. You can buy the specified meter for only 2700 rubles.
Presented electricity meter(single-phase) is sold with quality pass-through resistors. The nominal voltage of the device is 250 V. The meter is not afraid of overloads from the network. However, it is important to note that it is not particularly compact in dimensions. To install the model is allowed only with adapters on two terminals.
The sensitivity threshold of the device is 0.2 A. In the current circuit, the power of the meter is 10 W. The minimum permissible temperature of a one-rate counter is -20 degrees. Check the product every five years. In the store, the counter can be found at a price not more than 3400 rubles.
Presented electricity meter(single-phase) is produced with a field effect transistor. In total, the model has two capacitors. The threshold sensitivity of the device is 0.3 A. The directly rated voltage does not exceed 230 V. The atmospheric pressure of the meter is 80 mm Hg. Art.
Having listened to the customers' feedback, you canunderstand that the model is installed quite simply. In size it is not compact. The indications are noticeable quite distinctly. The relative humidity of the meter is 60%. It is necessary to check the presented device every five years. The minimum permissible temperature of this counter is -25 degrees. The operating frequency of the device is 55 Hz. The price for such a meter fluctuates around 3100 rubles.
This electricity meter (single-phase)is sold with a high class of accuracy. In total, the model uses two through capacitors. Take the device to two-rate modifications. For adapters on three terminals, the device is not suitable. If you believe the reviews of buyers, the glitches are rare. It is also important to note that the readings on the panel are seen well.
The sensitivity threshold for the model is 0.3 A. The relative humidity of the modification is 55%. You need to check the counter every three years. Problems with overheating of capacitors are rare. The operating frequency of the modification is 58 Hz. The minimum permissible temperature of the meter is -23 degrees. The model is sold at a price of 2900 rubles.
The specified electricity meter (single-phase)is in great demand. First of all, it is chosen for compactness. For adapters on two terminals it fits well. The data in the panel is clearly visible. Speaking of the indicators, the power in the current circuit is 4W. In this case, the minimum temperature of the counter is not more than -20 degrees.
Problems with turning off the device are rare. This is largely due to the presence of a protection system. The atmospheric pressure of the device is 80 mm Hg. Art. Its relative humidity does not exceed 55%. The maximum current in the circuit is 5 A.
For adapters to four terminals, the device does notis suitable. The dimensions of the counter are quite compact. Capacitors in the model are used with high throughput. The maximum permissible temperature of this counter is 55 degrees. Buy the device in the store can be for 3400 rubles.
