An Example of Device Selection for Motor Transmission Control (soft starter)
A three-phase thyristor rectifier bridge is required to control a DC motor. The suitable device is important to ensure the stable operation of the soft starter to control the motor and it must selected to coincide with the property of motor and requirement of system. The selection principle provi...Read more -
Precautions of Replacing the Thyristor or Rectifier
When we replacing the disc type thyristor or rectifier, the following issues should be noted: 1. The first thing should pay attention to is the contact areas of the device two sides as well as the top and bottom contact area of the heatsink. Any pits, burrs or articles…etc on the surface which wi...Read more -
