Frequency converters for three-phase pumps - CUE
/ Motors, Controls And Accessories / Frequency converters for three-phase pumps – CUE
UP, UPS Series 100
Technical data:-
Mains voltage:
- 1 x 200-240 V
- 2 x 200-240 V
- 3 x 380-500 V
- 3 x 525-600 V
- 3 x 575-690 V
Applications :-
Adjustment of the pump performance to the
demand. Together with sensors, the CUE
offers these control modes:
- proportional differential pressure
- constant differential pressure
- constant differential pressure
- constant pressure with stop function
- constant level
- constant level with stop function
- constant flow rate
- constant temperature
The CUE can also be controlled by an external signal or via GENIbus
Features and benefits :-
- Adjustment of the pump performance to the demand, thus saving energy.
- Easy installation, as the CUE is designed for Grundfos pumps.
- Short-circuit-protected output; no motor-protective circuit breaker required.
- Fault indication via display and a relay, if fitted.
- External setpoint influence via three programmable inputs.
