Anda Digital Potentiometer EDP2041

Potentiometer:

A potentiometer consists of a rotary resistive element inside a casing that is used to divide voltage in circuits. This resistive element can be wirewound, film, or carbon. Two terminals are connected to the two ends of this resistive element, and the resistance value between these two terminals is always fixed, representing the ohmic value of the resistive element. Between these two terminals, there is another terminal connected to a movable contact, and this movable contact can slide on the resistive element, changing the resistance between the middle terminal and each of the side terminals. To move the movable contact on the resistive element, one end of the resistive element is connected to a knob or to a slotted plate that can be adjusted with a screwdriver.

The change in resistance between the middle terminal and one of the side terminals can be linear or non-linear with respect to the rotation of the knob or slotted plate; based on this, the potentiometer is called linear or non-linear. In a linear potentiometer, for equal changes in the knob position, the resistance change between the middle terminal and each side terminal is equal. For example, in a linear potentiometer, if rotating the knob from zero to 90 degrees causes the resistance between the middle terminal and a side terminal to increase from zero ohms to 1kΩ, then rotating the knob from 90 to 180 degrees will increase the resistance from 1kΩ to 2kΩ. Usually, the resistance value between the side terminals (the ohmic value of the resistive element) is written on the potentiometer; if this value starts with the letter B, it indicates that the potentiometer is non-linear, meaning for equal knob changes, the resistance change between the movable terminal and each fixed terminal is not equal but follows a non-linear pattern. In other words, the resistance variation curve between fixed and movable terminals with respect to the movable contact rotation is non-linear.

What is the difference between a potentiometer and a rheostat:

Both potentiometers and rheostats are variable resistors, but the potentiometer is used to control voltage in part of the circuit, while the rheostat is used to control the current in the circuit. Also, if three rheostats are used in the circuit, their operation will be like a potentiometer and voltage control can be achieved.

Note: Today, to facilitate automation processes, instead of using a potentiometer (variable resistor), we can use a digital potentiometer, which easily allows scaling the desired information and obtaining an analog output from the digital potentiometer to connect to controllers such as inverters.

Points to know when buying a potentiometer (variable resistor):

Potentiometer resistance value
Number of turns of the potentiometer
Number of pins
Physical shape

Import of Various Inverters

Considering the needs of the electronics industries in Iran and the unavailability of some rare and specialized components, to compensate for this shortage, it is necessary to resolve the issue through imports from other countries such as China, Dubai, Turkey, or European countries. However, on the other hand, due to the emergence of intermediaries and profiteers, problems such as increased costs, delays in order deliveries to customers, occasional technical issues with components, and difficulties tracking orders from registration to product receipt have arisen. With the growing need for optimized energy management and the remarkable growth of industrial, construction, and solar system projects, the demand for inverters in the Iranian market has significantly increased; because inverters play a key role in converting and controlling electrical current, they have become one of the best-selling and strategic goods in the import sector. Meanwhile, imports from China and Dubai, as the two main sources for supplying these equipments, have increasingly attracted the attention of traders and sellers. China, as the main hub for producing electronic equipment, manufactures various inverters in diverse qualities and competitive prices. Although China is more economical in terms of price, importing from Dubai also has its specific advantages. For example, geographic proximity, faster shipping, the possibility of in-person evaluation of goods, and facilitation of customs clearance processes are among the reasons many traders import inverters from Dubai. Also, Dubai, as an intermediary market, offers a wide variety of Chinese, European, and Asian brands to importers. At Fartak Tejarat, with over ten years of experience in official, semi-official, and even small-ship imports, we have endeavored to make all stages of this complex process simple, fast, and profitable for our customers, and based on the weight, volume, and value of your goods, we suggest the best shipping method and provide delivery to your warehouse door so that traders can purchase with greater peace of mind.
