American Control Electronics ACT400-10

The ACT Series drive, specifically model ACT400-10, offers a cost-effective solution for controlling single-phase AC motors such as permanent split capacitor (PSC), shaded pole, synchronous, and universal motors. This drive utilizes variable voltage with a constant frequency, which is particularly suitable for applications with a limited speed range.

One notable feature of this drive is its ability to maintain approximately constant pressure in filtered fan applications. As filters become obstructed, the motor dynamically adjusts its speed to uphold airflow, ensuring optimal performance. Additionally, the ACT400-10 incorporates an internal closed-loop circuit that stabilizes motor voltage during fluctuations in AC line conditions, such as sags or swells.

This model also accepts feedback through a thermistor or voltage signal, enabling the creation of a PI loop for enhanced control. The ACT Series drive is equipped with a chassis enclosure and supports input voltages of 115 and 230 VAC, with a maximum current of 10 AAC.
