The CFW501 inverter line has been developed with dedicated features for HVAC-R applications. With compact size and special functions for this market, it is the ideal solution for pumps and fans, and can be used in shopping centers, hospitals, hotels, airports or similar.
Main characteristics:
- Built-in RFI Filter: reduces signals of high frequency electromagnetic interference;
- Low harmonic distortion: meets IEC61000-3-12 standard;
- SoftPLC: adds the features of a PLC to the CFW501;
- 2 control loops with PID: cost reduction and increased reliability, eliminating external drivers for fan coils;
- Communications protocols on the interface RS485: BACnet MS/TP, Metasys N2 y Modbus-RTU;
- Conformal coating in all versions.
Function:
1. Fire Mode
- Function that inhibits internal faults, keeping the motor runing even in adverse conditions
2. Sleep/Wake up Function
- It optimizes the use of the motor and pprovides electric energy savings
3. Broken Belt
- It monitors the motor torque and prevents the operation with no load in case the belt breaks
4. Energy Saving Function
- Depending on the motor speed and load conditions, the flux is reduced, decreasing the losses and improving the performance
5. Bypass
- By mean of one of its relay outputs, the CFW501 allows the motor to the switched to the main power supply, using an external contractor
6. Short Cycle Protection
- It avoids loads such as compressors to be turned on and off successively in short periods, increasing the equipment service life
7. Dry pump
- It protects the pump in case of lack of water and indicates the fault
Applications:
- Pump and fan
- Convention centers
- Hospitals
- Airports
- Commecial buildings
- Hotels
- Shoppings
