Description
CUE 3X525-690V IP21 200KW | CUE is a complete range of external frequency converters designed for speed control of a wide range of Grundfos pumps. CUE has a built-in PI controller and offers the same functionality and user-interface as Grundfos E-pumps. CUE solutions can thus be seen as an extension to the E-pump range. By choosing a CUE-solution, you will get the following benefits: Grundfos E-pump functionality and user-interface
application- and pump-family-related functions
increased comfort compared to fixed-speed pumps
very easy installation and commissioning compared to standard frequency converters
speed control of pumps up to 250 kW
speed control of pumps installed in potentially explosive environments. CUE offers the following inputs and output: RS-485 GENIbus
an analog 0-10 V input for external setpoint
an analog 0/4-20 mA input for sensor
four digital inputs for various functions, for instance external start/stop
two signal relays (C/NO/NC). Accessories: Input/output add-on boardProvides additional input: one 0/4-20 mA analog input for an additional sensor
one 0-20 mA analog output
two inputs for Pt100/Pt1000 temperature sensors, for instance for bearing monitoring. Motor filters: For reduction of dU/dt and peak voltages to the motor windings and for reduction of the acoustic noise generated in the motor, a number of motor filters are offered: dU/dt filters , 11-250 kW
Sine wave filters, 0. 55-250 kW.
