Linear DC Chokes
We manufacture, to order, linear DC chokes, suitable for the elevator industry.
In many applications it is essential that the choke exhibits a constant inductance up to and beyond a specified overload current limit.
In order that a guarantee of the inductance values obtained under these conditions can be given, we have designed and built our own DC choke tester. A curve showing the variation of inductance against current can be supplied with any choke ordered from us.
