Thyristors, also known as solid-state relays, are semiconductor switches. TRIACs are a type of thyristor capable of controlling current in both directions. TMA104S-L is a thyristor module specifically designed for use in low voltage and medium voltage applications, such as lighting, heater control and motor control. This article will discuss the application field and working principle of TMA104S-L thyristor module.

TMA104S-L is a versatile thyristor module that can be used in a wide variety of applications, such as lighting, heater control, motor control, and more. These modules are designed for use in permanent magnet three-phase synchronous motor applications, and can be used to control AC or DC motor loads as high as 10A. The module also provides many protective functions, including over-temperature protection, over-current protection, automatic thermal shutdown, and over-voltage protection.

The working principle of TMA104S-L is based on the principle of a silicon controlled rectifier (SCR). The SCR consists of four terminals: an anode, a cathode, a gate, and a control. When the control terminal is open, theSCR will remain in an off state, regardless of the voltage applied to anode and cathode. When the control terminal is closed, electrons will flow from the anode to the cathode, and a conducting state is established. This is known as the “on state” of the SCR. TMA104S-L employs this principle to provide two-way power switching, allowing it to control current in both directions.

TMA104S-L thyristor modules also feature a built-in LED indicator for rapid operation confirmation. The LED will light up when the control terminal is opened, and it will turn off when the control terminal is closed. This allows for quick visual confirmation of correct operation. The module also features reverse polarity protection, so it will not be damaged by accidentally connecting it to a supply with reversed polarity.

TMA104S-L thyristor modules are highly reliable and have a wide range of applications. They are suitable for applications such as heaters, motor control, lighting, and more. In addition to providing over-temperature, over-current, and over-voltage protection, the LED indicator makes the device easy to diagnose. Thanks to its lightweight design, it is ideal for use in tight spaces, such as fuse boxes. TMA104S-L is an excellent choice for a wide range of controlling applications.
