The TA10-D drive delivers the features and benefits of a microprocessor based drive, and the low cost of a triac control. This control is perfect to control speed of a single phase AC motor.
The industrial strength TA10-D has a continuous current rating of 10 Amps at 115 VAC and 9 Amps at 230 VAC. Other common triac drives are unable to maintain a steady voltage (speed) to the motor as the input AC line voltage sags or swells. However, the internal closed loop circuit on the TA10-D drive compensates for changing AC line voltages while maintaining a steady voltage to the motor, thereby maintaining speed.
The Minarik TA10-D drive takes advantage of single phase motor characteristics to provide approximately constant pressure in filtered fan applications. As the filter becomes clogged, the motor will speed up to maintain airflow.
The TA10-D is also capable of accepting a feedback signal. This feature is most commonly found in exhaust systems where a thermistor is used for feedback to maintain a set temperature. The drive can also take a set point voltage signal to create a PI closed loop system.
This unit contains Minimum Speed and Maximum Speed adjustable calibration trim pots. These pots allow calibration of the drive to prevent going below or above a certain speed, flow, or temperature.
Single phase permanent split capacitor (PSC), shaded pole, and synchronous motors can all be controlled by the TA10-D.
