In the modern power system, the digital energy meter has become an indispensable device. This article will introduce the characteristics, applications and working principles of digital energy meters.

With the development of electronic technology, the standard energy meter has also realized the transformation to digital and intelligent. Compared with traditional mechanical energy meters, electronic energy meters have various advantages such as high measurement accuracy, low power consumption, and strong anti-stealing capabilities. So, what is the working principle of the digital energy meter? What function does it have?

A terminal block is actually a connector that can be used for the interconnection of a large number of wires. There are single-layer and double-layer terminal blocks, which can be used for current, voltage, etc. A certain crimping area can ensure the reliability of the terminal connector and at the same time ensure that sufficient current can pass. The following article introduces the application of terminal blocks and the functions of different terminal blocks.

The pressure switch is a device combined with an electrical switch. When the preset fluid pressure is reached, it will perform a switch contact action to control the pressure. The pressure switch adopts high-precision, high-stability pressure sensor and transmission circuit, and realizes the functions of detection, display, alarm and control signal output of medium pressure signal through special CPU modular signal processing technology.

Rotary switches can be used to replace the rotary pulse generators of traditional resistive potentiometer analog functions. These rotary switches are usually used in the front panel of the instrument and the man-machine interface of the audio-visual control panel. The rotary switch uses a quadrature optical encoder as a purely digital device instead of an analog potentiometer, which is similar in appearance to a traditional or resistive potentiometer, and its internal structure is fully digital and uses optical technology. Below is the rotary switch price list.

A toggle switch is an electrical switch that is turned on or off using a lever or handle that moves back and forth. Toggle power switches and joystick switches are other names for this switch. This switch can be used in any electrical application as they are flexible devices. Since switches are usually manually operated, a toggle switch is essential as a simple switch in many circuits. So how much do you know about the wiring of the toggle switch? Next, ATO will lead you to learn the wiring knowledge of the toggle switch.

Electronic switches are an integral part of modern electronic equipment, used to control parameters such as on-off, direction and power of circuits. Among them, the rocker switch, as a common electronic switch, has a simple structure, easy operation and installation, and has been widely used in home appliances, automobiles, aerospace, industrial control and other fields. This article will introduce the applicable scenarios and structure of the rocker switch.

A resistor is a current-limiting element. After the resistor is connected to the circuit, it can limit the amount of current passing through the branch it is connected to. Nowadays, resistors play a huge role in controlling current and voltage. Next, we will introduce how resistors work and the maintenance of resistors.

The rocker switch is widely used in life and brings a lot of convenience to people's life. So do you know how to wire the rocker switch? Next, ATO will bring you knowledge about how to wire and select the rocker switch.

A toggle switch is a switch that performs opening and closing functions by toggling. Generally, we use it for the operation of some low-voltage circuits.
