AC Drives and Motor Controls

American Control Electronics offers two types of AC motor controls; Triacs and VFDs. All drives are designed to run on a single phase AC line with a single phase AC motor. However, some of our AC electronics models can run three phase motors as well. Power configurations consists of 115 in - 115 out, 115 in - 230 out, 230 in - 115 out, and 230 in - 230 out.

Triac

Triac

Triac drives output voltage while maintaining a constant frequency, making them perfect for single phase motors that a require a small speed range, such as fan applications. These units will run off a 115 VAC single phase line for a 115 VAC single phase motor, or a 230 VAC single phase line for a 230 VAC single phase motor. The output frequency is the same as the input frequency.

Variable Frequency

Variable Frequency

Our microprocessor-based variable frequency drives will output a voltage to the AC motor that varies the voltage and frequency proportionally. This allows the AC motor to be turned down to a much lower speed compared to a triac drive. The input can be 50/60 Hz single phase and the output is 60 Hz, single or three phase. Some models are design for a 115 VAC input with a 115 VAC output. Other models, called "doublers", are designed for 115 or 230 VAC in and only 230 VAC out.

The ACF group is a microprocessor structured Alternating current variable frequency build . The pieces of hardware appear and behave like DC pieces of hardware , meaning simple and highly effective setup without the technical skills . All of these pieces of hardware are combined with operator adjustable trim pots to establish Maximum . Speed , Min . Speed , Fail Comp , Enhancement , TQ Limit , Accel and additionally Decel / Injection Braking limitations . ACF700 pieces of hardware allow for a 115 or 230 VAC input with a 115 or 230 VAC output , autonomous of the input possibility . The reason being that the ACF700 benefits from an extraordinary voltage doubling capacity that will permit anyone to manage a 230 VAC generator while just a 115 VAC solitary phase force may be found .

The PMF Series is a adjustable frequency drives designed to run 115 or 230 VAC motors, whether single phase or three phase, at 50 or 60 Hz.  With our "Doubler Mode", the PMF Series will allow a 230 VAC output to be set with a base frequency of 50 or 60 Hz at 115 VAC.
