CAREL presents variable frequency drives

CAREL has presented the range of variable frequency drives (VFD), the NXL series, compact inverters designed specifically for applications. Offering IP54 protection rating, the NXL Series Inverters feature single/3-phase power supply and 3-phase output. Control can be performed using 0-10 V or 4-20 mA analog signal or Modbus standard via serial communication. Units are suited for applications such as variable speed of fans in air handling systems, modulation of compressor operation, variable flow rate of system supply pumps, and control of condensing pressure in fan assemblies.
