VFD300-4 AC Motor Control

VFD300-4 AC Motor Control

VFD Series

The Volts/Hertz VFD Series has several models in the 1/16 - 1 HP range that accept 115 VAC and 230 VAC power. VFD600 models have a jumper that causes the drive to double the output voltage, allowing the use of 230 VAC motors when only a 115 VAC power is available. The VFD Series was designed to “look and feel” like a DC drive. This means quick and easy setup with no programming required. With its compact size, standard features, and application flexibility, the VFD Series is an excellent choice for most 1 HP and under AC applications. The VFD Series can also run single phase permanent split capacitor (PSC), shaded pole, and synchronous motors.


Potentiometer Kit 202-0101 is included with a purchase of the VFD300-4

Variety of Motors: Permanent Split Capacitor (PSC), Shaded Pole, Synchronous, and 3Ø Induction

Torque Foldback: Allows up to 200% torque for short periods to overcome intermittent peak loads, then reduces the torque to a (preset) safe level

Adjustable Switching Frequency: Default 16kHz frequency can be changed to 4k, 8k, 10k, or 12k Hz using kit 202-0108. Higher frequencies result in audibly quieter motor operation, but lower frequencies produce less electrical noise and may prevent GFI tripping.

Diagnostic LEDs: Power, Torque Limit, Fault (Undervoltage, Overvoltage, 250% Current Limit Trip)

User Adjustable Calibration Trim Pots: Maximum Speed, Torque Limit, Boost, Acceleration and Deceleration
