Product Description:

The VACON0100-3L-0061-4-HVAC+SBF2+IP54+DLDE is an AC variable-frequency drive produced by Danfoss for the VACON 100 Industrial Drives series. It converts fixed utility power into a regulated output that allows controllers to vary induction motor speed in pumps, fans, or material-handling equipment, improving process accuracy and energy use in automated plants. The enclosure carries an IP54 / UL Type 12 rating, protecting the drive from dust and noncorrosive splashes without requiring a separate cabinet.

The drive connects directly to a three-phase AC mains supply and can be reenergized no more than once per minute, as limited by its maximum mains connection rate. Under continuous load, it delivers a nominal current of 61 A while maintaining a displacement power factor greater than 0.98. Internal DC-link filtering limits output voltage ripple to a maximum of 100 mVrms. Two isolated analog inputs provide ±1% accuracy with 0.1% resolution, allowing precise scaling of process feedback signals. The analog output channel provides ±2% accuracy and 0.1% resolution, and it can drive loads up to 500 Ω for signal transmission to supervisory systems. A single-pole, double-throw relay provides Form C signaling for fault or ready indications.

The control electronics are powered by an auxiliary bus at 24 VDC, which can supply a maximum of 250 mA to external sensors. The reference port supplies 10 VDC, simplifying the use of potentiometers for speed commands. Immunity to conducted and radiated disturbances complies with IEC 61800-3, allowing the unit to operate near sensitive PLC input and output modules. The isolated analog channels help prevent ground-loop interference from affecting process signals. The SPDT relay contact supports either a normally open or normally closed circuit without additional interface hardware. Its combination of analog inputs, an analog output, a reference supply, and relay signaling provides the connections needed for common pump and fan control arrangements.
