The solid state switches IS.../…SF “PLUS” exceed the limitations of electromechanical switches for many difficult and demanding applications, such as the control of high power motors, transformers, tungsten lamps, heating elements, electric furnaces, etc.
The IS.../…SF switches of the “PLUS” series have an extremely long service life since they have no contacts subject to wear, are silent and generate almost negligible radio-frequency interferences. For this reason, they are suitable for use in applications where acoustic or electric noises represent a problem.
Thanks to the total absence of moving parts, they can operate in very dirty atmospheres without being altered and/or damaged.
The IS…/…SF switches of the “PLUS” series range between 100A and 460A and are suitable for all types of power supply lines. Protection fuses and RC groups provided.
The three-phase execution is implemented using no. 2 or 3 single-phase static switches; compact executions are also available with 2 or 3 static switches.
Every standard model is made of modules in an insulated box, mounted on heat sink with or without fan, according to the flow rates.
