Three-phase common mode chokes WT range 3.5A to 70A

Almag three-phase common-mode choke standard range

Experience gained from working with customers for over twenty years, to find the best balance between performance and cost, allows us to offer standard ranges of chokes optimised for particular applications, all with well defined inductance and current handling capabilities. WT range chokes are low cost, open-construction chokes, with current ratings from up to 70A.

lc

Rated AC or DC current

Based on efficient natural convection cooling.

L0

Inductance per phase

Nominal figures in millihenries, at 10kHz

DCR

DC resistance per phase

Nominal figures in ohms, at 25 degree C For chokes with windings type D and type T the figure applies with the windings connected in parallel.
