SP SERIES CONTROL PANELS WITH INVERTER Control panels with inverter SP series modulate the operation of electro pumps responding to the pressure trasducer control (measured by flow rate or other external signal 4-20 mA passive) adjusting the speed of the electric pumps to maintain constant the system demand. TECHNICAL DATA • Power supply voltage: 400V ±10%, • Three phases without aid of the neutral • Power supply frequency: 50Hz or 60Hz • Power for every motor: from 0.75 kW and above • Type of start-up and power supply for all pumps: - during the start-up phase, the inverter powers the pump with a voltage ramp, the other pumps have direct or star/delta start-up according to the electric power - during emergency functioning (controlled by pressure switches) all of the pumps function according to the power size at direct or delta/ triangle start-up • Limits of use (environment temperature): from -10°C to +40°C • Protection rating: IP55 up to 3 kW IP44 for greater powers Conformity to the CE mark, EN 60204-1; Security electrical equipment. - EN 60439-1; Switchgear and controlgear assemblies.
