Variable Frequency Drives range from 0.37-30 kW.October 3, 2008 -
Offering IP54 protection rating, 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.

Compact Dimensions and High Performance: the Range of CAREL Inverters
CAREL presents the new range of variable frequency drives (VFD), the NXL series, compact inverters designed specifically for applications such as:
o variable speed of fans in air handling systems
o modulation of compressor operation
o variable flow-rate of system supply pumps and evaporator pumps on chillers
o control of condensing pressure in fan assemblies
Inverters are used on the electric motors that drive water pumps or fans to modulate the load and achieve precise and energy efficient process control. The variation in compressor speed by inverter, as well as ensuring extensive modularity in relation to the load, allows the continuous operation of the compressor, bringing benefits in terms of cooling efficiency and considerable overall energy savings.
The NXL series is available in power ratings from 0.37 to 30 kW, with single/three-phase power supply and three-phase output, index of protection up to IP54, for all variable flow-rate applications. Control can be performed using a 0 to 10 V or 4 to 20 mA analogue signal or Modbus® standard via serial communication, thus integrating the functions of the device with the software for managing the pCO series controllers or the PlantVisor PRO supervisor. The range can also be used with a removable control panel with remote RS232 seraial connection. A PC can be used as an alternative to the control panel for managing the inverter.
Other advantages include:
o wide operating range
o easy installation and use
o low noise levels
o high index of protection against electromagnetic disturbance
o compact and thin "book-style" design
The NXL series is the ideal solution for all environments, completing and enhancing the range of CAREL products for maximum efficiency and energy svings in HVAC/R systems.
