Thyristors - SCRs - Modules: M252515V Application Field and Working Principle

The M252515V Searching Controller (SCR), also known as a Thyristor, is a three-terminal, solid-state power switch that can control the flow of electric charge. It is a current-controlled device and is one of the most important components in switches, electric motors, power supply, UPS, and inverters. This article will discuss its application field, properties, characteristics, and working principle.

Application Field

The M252515V SCR is widely used in various electronic devices and equipments, such as UPS and electric power controlling relays. Additionally, they are used as phase control elements in circuits and as motor control elements. It can also be used as DC switching components, AC voltage stabilizers, soft start relays, and other circuits, making them quite versatile.

Properties and Characteristics

One of the main advantages of the M252515V SCR is its high voltage, low current, and surge current capabilities. It has a low on-state voltage drop of 0.45 to 0.50V, and its forward blocking voltage range is up to 600V or more. It also has a fast switching time. The M252515V SCR has a high insulation resistance which makes it very reliable and durable. Furthermore, it has an excellent temperature rise, extended life cycle and low noise.

Working Principle

The working principle of the M252515V SCR is based on the effect of controlling an electric current in a single direction. The device consists of two parts: a main control electrode such as a gate and two base electrodes, most commonly known as an anode and cathode. When a voltage is applied to the gate, it creates a reverse bias and silicon creleased from the gate enters the region between the anode and cathode and conduct an electric current. This current increases as the gate voltage increases, until it reaches a set cutoff point. After this point, the current will remain constant and will not increase any further. In conclusion, the M252515V SCR is a reliable and versatile device that is widely used in various electronic devices. Its application field includes UPS, electric power controlling relays, and motor control elements. Its working principle is based on the effect of controlling electric current in a single direction and allows for fast switching and a low on-state voltage drop. In addition, the device has a low noise level and excellent insulation resistance.
