MA 2705 Decade inductance is intended for all application areas where inductance variation/selection by hand is required. It is passive electric device housed in metallic case. It consists of 3 decades for selection of the inductance in range of 0 mH up to 999 mH. Set value is directly visible on decade’s dials. MA 2705 Decade inductance uses ferrite chokes providing accuracy of 5 % at 50% of rated current.
