Filters (rectifiers) of the electrical type are used in various devices to stabilize the input voltage. The principle of operation of the devices is based on lowering the operating frequency.
Standard model includes controller, resistors and also tetrodes. Connection of modifications is carried out through contact adapters. The main parameters of the modifications include the maximum overload, operating voltage and output resistance.
Device types
Today, there are various types of electrical filters. First of all, they are divided by operating frequency. Low-frequency devices are made with several resistors and have low conductivity. Controllers are most often used of the wave type and are installed with capacitors. High-frequency modifications are made with collector adapters.
The voltage indicator for models of this type is on average 200 V. By design, filters are ceramic, piezoelectric and bandpass. Additionally, there are notch modifications. By security, active and anti-jamming devices are distinguished.
Assignment of models
Electrical low-pass filter, usually used in AC networks. For power equipment, it is not suitable. High-frequency filters are installed on conveyors and machine tools. They can be used in a network with alternating current.
Ceramic and band devices are fixed to toggle switches. They can also be found in ventilation systems. It is also important to note that active devices are used for pumping stations. An electric noise filter is used in drive mechanisms.
Low frequency models
Low-pass type filters have recently been often stared at conveyor devices. Direct connection of modifications is carried out through an adapter. The transistors of the models are set to 120 and 200 V. The direct operating frequency of the filters fluctuates around 20 Hz. Models are not suitable for drive mechanisms.
It is also important to note that different types of capacitors are used in devices. On average, their maximum capacitance is 5 pF. If you trust the reviews of experts, then the model is not suitable for toggle switches. The conductivity index of low-frequency modifications is not very high. They are produced in a steel case. Modifications with two-pin outputs are very rare.

Models are poorly suited for ventilation systems. It is forbidden to install filters in an alternating current circuit. Devices with 3 pF capacitors are very rare. The output connectors are most commonly used three-pin type.
Triggers are found only in the distribution type. Connection of models to drives is carried out through comparators. The output voltage of the filters is on average 230 V. The sensitivity indicator in this case depends on the resistors. The connection to the drive conveyors is via a varistor. The specified element is most often used with several adapters. To increase the voltage, the high-pass filter has a stabilizer.

Stabilizers are installed to lower the voltage. Many filters of this series have an adjustable contactor. Models are not suitable for pumping stations due to low sensitivity to impulse noise.
Pilot series devices
The Pilot filter is used for conveyor devices. The modification consists of field-effect transistors, as well as one linear controller. It is connected to the block through a channel adapter. If you believe the reviews of experts, then the filters of this series are not suitable for contact toggle switches. The triggers are set directly to the active type.
