It is fitted with the advanced MG Flex variable frequency driven motor that offers the following features: • Runs at varying speeds depending upon the energy input available. • Can be used for DC or AC power supply and can therefore be connected to either PV solar modules, a standby AC generator or mains power supply as required. • Built in protection for under and over voltage and system overload. No additional protection is therefore required. • One set of terminals is included for either high or low-level control functions. Product image Informações técnicas importantes 4 Multiple models are available, all powered by the same 1250 W motor providing a selection of head and flow outputs depending on the application.
