Chokes AC & DC

TMC manufacture a wide range of chokes, inductors & reactors generally designed for a specific application as explained below:-

• AC iron cored chokes Single & three Phase. Frequency range of 16Hz to 1500Hz. Voltages up to 690V & currents up to 1000A we can also design & manufacture swinging chokes that will give a change in inductance at a given change in current. Typical applications: inverter drives, welding, line reactors & conditioners, Neon Lighting.

• AC air cored inductors For filter & high stability applications, these can be toroidally wound.

• DC smoothing & drive chokes With dc currents from 10mA to 1000A. The photo shows a DC smoothing choke for a test rig. It has eight windings for series/parallel operation, to give a maximum inductance of 200mH @ 30A DC or a minimum inductance of 3.12mH @ 240A DC continuous.

• AC & DC ferrite chokes, Which can be wound on toroidal cores, rods, pot , ‘E’ & RM cores.

The above range of chokes can be open or enclosed types to various IP ratings. They may be varnish vacuum impregnated for low noise or where there is a high relative humidity, can be tropicalised.

Terminations may vary to suit the application, but these are typical:- Flying leads, busbar, stud terminals, ring crimps, pcb, solder tags, & terminal blocks.
