Standard Design De-buzzing Chokes
De-buzzing chokes are designed to reduce transformer noise caused by dimming low voltage Halogen lighting fixtures. Using most types of dimmers in conjunction with a low voltage toroidal transformer may cause the transformer to produce a noise best described as a buzzing sound. If the transformer is not in a remote location the noise may be annoying. Our de-buzzing chokes will smooth out the broken sinusoidal waveform to the transformer, significantly reducing the buzzing noise. The chokes come fully encapsulated in black epoxy with a 1/4" center hole for easy one-bolt mounting. Flexible multi-stranded lead wire simplifies termination. Call the factory for volume discount.
