Dc Chokes

Transpower is globally acknowledged as trusted Dc Chokes manufacturer in India and in abroad as well. We manufactured Electric DC Chokes , and many other products in our housing, manufacturing facility so we are able to test the quality of the each and every product before handing over to the customer.

DC Line Chokes, also referred to as DC Link chokes, are used to of filter & control the DC bus voltage and current in variable speed drives.

They help reduce AC input line current harmonic distortion while absorbing DC bus voltage spikes and add protection and filtering but should not be considered a direct alternative to AC Input or Output Chokes.

They also offer the advantage of maximising the circuit inductance for power quality reasons, but without causing an AC input line voltage drop.

We are highly appreciated in the national and the international market for the best quality, competitive price and on time delivery of consignment. For any other information related to our products feel free to send enquiries.
