PMF703-3 AC Motor Control

PMF703-3 AC Motor Control

PMF Series

The PMF Series is the latest offering in a growing list of VFDs from American Control Electronics. Able to control 115 and 230 VAC, single and three phase motors, the PMF Series is designed to meet the market demands of VFD users who wish to simply run their motors without the complicated menu-driven setup typical of most VFDs today.

The onboard microprocessor allows for custom programming for OEMs. Whether it’s as simple as changing the purpose of a jumper, input, or trim pot, to programming entire routines and behaviors specific only to the OEMs application, the PMF is great for integrating PLC like functionality into your operation. Doing this can eliminate the need of a separate PLC altogether or enhance a system that currently does not have one.

The PMF Series has been tested to the 61800-5-1 Standard and is UL listed in the US and Canada, and includes isolation for remote control from an analog signal.

Potentiometer Kit 202-0177 is included with a purchase of the PMF703-3

  • UL 61800-5-1 Listed: Tested to the new UL standard to be implemented in 2020.
  • Microprocessor based: Allows custom programming for OEM’s.
  • Control a variety of motors: 3-phase induction motors, single-phase permanent split capacitor (PSC), shaded pole, and synchronous motors.
  • Doubler mode: Can double a 115 VAC line to run a 230 VAC motor.
  • Isolated inputs: Accepts floating or grounded signals 0 ± 5 VDC, 0 ± 10 VDC or 4-20 mA.
  • Diagnostic LED: LEDs for power and status (undervoltage, overvoltage, short circuit/current trip, overheating warning/trip).
  • Thermally protects: Drive recognizes when overheated as a result of overload. It first flashes a warning code on the status LED and will eventually trip if the condition persists.
  • Stopping modes: User can use DC Injection braking, decelerate, or coast the motor to a stop.
  • Dump circuitry: Internal circuitry for the hookup of an external dump resistor.
  • Quadrature encoder option: For OEM applications, the drive can be programmed to follow quadrature encoder feedback without any circuitry changes.
