Thyristors are a key part of any electrical system and are used extensively in both commercial and industrial applications. The MLO175-12IO7 is one particularly popular thyristor module from suppliers like the well known SCR Solutions Inc., and it can be used in a wide range of applications. This article outlines the MLO175-12IO7’s common application fields and its working principle.

Fields of Application

The MLO175-12IO7 is an ideal control element for power switching applications. It is suitable for controlling motors, incandescent light dimmers and other load applications. The assembly also provides impact-resistant and temperature resistant ceramic heatsinks to ensure safe operation. It is also used for frequency converters and inverters, as well as some soft starter systems. Moreover, thanks to its high peak current rating, it makes a good candidate for both linear and pulse width modulation (PWM) applications.

The MLO175-12IO7 is increasingly being used in the automation sector, especially in the field of rail transport. It is put to use in certain parts of the brake module, in the control of traction motors and in controlling other devices like wiper blades and air conditioning systems. It is also used in robotic applications, although the exact applications vary depending on the type of robot.

Industrial applications also often require a reliable and extremely mobile thyristor assembly, which is where the MLO175-12IO7 comes into its own. In the process of producing industrial machinery, a wide range of electrical processes occur and the MLO175-12IO7 is used for a variety of tasks. Examples include controlling valve actuators, steering, detecting circuit breakers and other switchgear.

Functionality

The MLO175-12IO7 is a three-phase thyristor module (as opposed to a single-phase device) of the SCR (silicon–controlled rectifier) type. It features three identical thyristors connected in just one compact space and the SCRs, or thyristors, switch on and off individually depending on the electrical flow through each one, meaning that all the modules are always in connection with one another.

The MLO175-12IO7 has gates on each thyristor. When the gate is opened, the thyristors switch on and conduct electric current in one direction. When the gate is closed, the thyristor stops conducting current. This process is what enables the module to be used with PWM applications, as the gate can be opened and closed very quickly in order to switch the current at the desired rate.

The MLO175-12IO7 is designed to work alongside other frequency-inverter-type components, meaning that it can increase or decrease the frequency of AC power as needed in order to adjust it for the required application. It also has positive temperature coefficient (PTC) thermistors included which will reduce the voltage of the three-phase circuit as the ambient temperature rises.

Conclusion

The MLO175-12IO7 is a reliable and versatile thyristor module which can be used in a variety of applications. It is especially useful for use in three-phase motor control, power switching applications and PWM applications. It is becoming increasingly popular in the railway and automation sectors, as well as in industrial manufacturing.
