PML Series

Model: PML703-5

American Control Electronics

The PML series is a general purpose drive for a wide variety of trapezoidal-wound brushless motors. With either a 115 VAC or 230 VAC line source, our drive can control motors that vary in the 90 to 280 VDC range, up to 5 amps or 1.5 HP. With the use of on-board trim pots, you can quickly set the maximum and minimum speeds, acceleration and deceleration rates, motoring and regening current limits, and the proportional and integral feedback gains. Each drive is designed for feedback from 120° hall effect sensors, and can be commanded with a wide range of analog inputs with our built-in isolation. The drive is a 4Q PWM controller, allowing the unit to be used as a unidirectional or bidirectional controller. The microprocessor based design means it can be modified to fit OEM specific applications.


  • Microprocessor Based: Allows custom programming for OEMs
  • Auto Ranging Input: No input voltage switches to set. Accepts AC or DC input: Can accept 80-340 VDC or 90-240 VAC input
  • Doubler Mode: Drive can double the internal voltage to allow for 240 VDC output with only a 115 VAC input
  • Stopping Modes: Enable (N.C.) can be set for coast or brake. Can be used for rapid starting and stopping
  • Thermally Protects: Drive recognizes when overheated as a result of frequent overload. It first flashes a warning code and will trip if condition persists
  • Diagnostic LEDs: Power, Status (Undervoltage, Overvoltage, Short Circuit / Current trip, Overheat Warning, Overheat Trip)
  • 4Q Reversing: Regenerative / 4-Quadrant drives have the ability to perform quick and contactorless braking and/or reversing-on-the-fly
