Product Description:

The Pacific Scientific SC105-010-T4 controller features a shunt regulator, 3 input phases and 320 V nominal bus input voltage. It is designed to run demanding industrial tasks with extreme efficiency and accuracy. A servo controller is typically built with a shunt regulator, a circuit element that protects the power supply against transient overcurrent.

When the servo motor slows down or a brake occurs, too much electrical energy is produced and retransmitted back to the controller. Without proper management, the power of this energy may result in a high voltage that may damage the controller or other parts. This is overcome using the shunt regulator, which redirects (or shunts) the excess energy to a resistor, where it is harmlessly dissipated as heat. This automatically switches on when the bus voltage is more than a safe level, and this keeps the system within the safe operating range. In conclusion, the shunt regulator ensures that both the controller and the entire drive system are safe. It is reliable against sudden stops, and load changes of the motor are amplified by the shunt regulator.

The controller works with a 3-phase 230 VAC input and gives a 320 VDC nominal bus voltage that evenly and efficiently powers servo motors. The continuous power of the shunt regulator is 60 W, and 15 kW is the peak power that can be supplied for almost 300 milliseconds. The SC105-010-T4 has a switching frequency of 5 kHz and efficiency greater than 95%. This makes it more economical and guarantees the reliable performance of the motor. All in all, this controller is perfect for industries that require robust, stable, and effective motor control in a harsh industrial environment.
