The EFD30/15/9 is a wetted non-inductive resistor manufactured by Feryster. It is a three-package component that consists of two channels of fixed resistances and a shunt resistor in between. The two channels are each rated a maximum of 30W at a resistance value of 15 ohms and the shunt resistor is rated a maximum of 9W at a resistance value of 9 ohms. The component is designed to regulate currents, dissipate breakdown voltages, smooth pulsed currents, and provide overload protection in various types of lighting, heating, and industrial control applications.
