Cu 300 The Control Unit Cu 300 Is Developed for The SQE Submersible Pump with PPO Construction

CU 300 The control unit CU 300 is developed for the SQE submersible pumps. The CU 300 enables: setting of operating parameters, and monitoring of operation and alarm indication, if any. The CU 300 indicates the following alarms: Over voltage, Under voltage, Dry running, Speed reduction, Over temperature, Overload, Sensor alarm. The CU 300 receives alarm signals from the motor for the following parameters: Incipient pump/motor defect. Too high temperature in motor electronics. Supply failure. As standard, the CU 300 incorporates an alarm signal relay. The CU 300 enables the use of: Remote control R100: Wireless infrared remote control by means of the R100 enables change of factory settings External sensors: Reception of data from external sensors and control according to the data received, External potentiometer SPP 1: Manual speed control.
