Thyristors, commonly nicknamed SCRs (Silicon Controlled Rectifiers), can be used to switch electrical current using a simple on/off concept. The TD190N18SOFHPSA1 is a three phase AC motor controller module designed to switch power stages quickly and accurately to accurately control motor speed. This module is ideal for applications requiring precise motor speed control such as AC speed drives, servo motors, and adjustable speed starters.

The TD190N18SOFHPSA1 module is comprised of three SCRs, a current transformer and diodes mounted onto a single heatsink for heat dissipation. Each SCR is rated for up to 1200 volts and 20 amperes continuous and the current transformer can handle up to 20 amps. This module is available in both two- and three-phase versions and can be used to control single-phase or multiple-phase motors.

The modulator utilizes a patented vibration control system that regulates motor speed based on input frequency. This allows for precise control of a motor’s speed as frequency changes and eliminates the need for controller resets when frequency changes occur. This also reduces motor noise, helping to reduce wear and tear on the motor.

The TD190N18SOFHPSA1 modulator operates using an “open-loop” method of motor control. This allows it to quickly switch power stages based on input frequency, allowing the motor to be accurately controlled without any need for feedback or complicated tuning. This open-loop operation also eliminates the need for complex sensing or feedback paths.

The TD190N18SOFHPSA1 module works in conjunction with an external power source, such as a variable frequency drive. The power source provides energy to the modulator, which is then used to regulate motor speed. The modulator can control both single and multiple-phase motors, with a maximum current rating of 20 amperes. The module is available in both two- and three-phase versions, allowing for compatibility with a variety of different motor types.

The TD190N18SOFHPSA1 module has many advantages over traditional motor control platforms. Its open-loop method of operation provides precise speed control without the need for feedback or tuning, while its vibration control system reduces motor noise. Additionally, the module is available in both two- and three-phase versions and can control a wide range of motor types. This makes the TD190N18SOFHPSA1 a versatile, reliable, and cost-effective motor controller.
