The VFD603 Series have all the features of the original VFD Series with several enhancements. They include a rugged steel or plastic NEMA 4X enclosure, an isolated front end, minimum speed adjustment potentiometer (pot), output voltage doubling, DC injection braking, and automatic or manual restart when power is restored. The VFD603 Series accepts reference signals that are 0-5 VDC, 0-10 VDC or 4-20 mA without an additional isolation card. The DC injection braking feature comes with two additional calibration potentiometers (Braking Current and Braking Time) for easy set up. There is never a need to program the VFD603 Series. The dual voltage VFD603 Series has a “doubling” jumper that can be set to output 230 VAC to the motor when only 115 VAC is available. Another jumper selectable option is for choosing automatic or manual restarting. The features, fl exibility and compact size of the VFD603 Series make it the ideal choice for AC motor applications under 1.5 HP in adverse surroundings.
