Private converter FC-202P11KT4P55H1XGCXOXSXXXXXXXDX
The Danfoss VLT® AQUA Drive FC-202 frequency converter is designed for water supply and sanitation systems: water utilities, pumping stations, aeration blowers, pumps with constant and variable torque: reciprocating mixing, dosing, boosting and submersible, etc.
With a wide range of powerful standard and additional functions, the VLT® AQUA drive allows you to achieve a minimum cost of water supply and drainage systems. The modular design provides functional flexibility and a large selection of easily connected additional devices that expand functionality.
Danfoss VLT AQUA Drive FC 202 Frequency Converter
The main functionality of the Danfoss VLT AQUA Drive FC 202 frequency converter:
- built-in functions and algorithms for working with pumps
- up to 3 feedback signals
- Dry running protection (VLT® HVAC Drive prevents premature pump failure by constantly assessing its condition using frequency and power measurements).
- Pipe filling mode (Controlled (closed loop control) pipe filling occurs; prevents hydraulic shocks, damage to pipes and sprinklers).
- The extreme point of the working curve (The function of detecting damage and leaks in the system. When the pump moves to the extreme point of the working curve, the drive will give an alarm signal, turn off the pump or perform another preset action).
- Built-in standard cascade controller (The built-in cascade controller allows you to control three pumps, one of which is the constant master).
- Alternation of motors (A logical function that ensures the alternate operation of two pumps. The built-in timer ensures equal pump loading coefficients).
- Flow compensation (Depending on the flow value, the function reduces the pressure setpoint value, resulting in energy savings).
- Initial acceleration (The initial acceleration function provides rapid acceleration of the pump to the minimum speed, starting from which normal acceleration occurs. This acceleration prevents damage to the bearings).
- 4 PID controllers with the possibility of modeling a dependent PID controller
- Automatic optimization of energy consumption (AEO)
- Automatic adaptation to the engine
- Flying start (picking up a rotating engine)
- Electronic Thermal Relay (ETR)
- Intelligent Logic Controller
- Built-in electromagnetic interference filter
- Vector and scalar engine control
- Built-in 24V/10V power supply for sensors/logic
- Sleep mode
- Communication protocols (Modbus RTU, Profibus, DeviceNet, EtherNet IP)
