four high-power iron-core chokes 3mH

[cocolino]

manufactorer: Hans-Kull AG, Switzerland
inductivity: 3mH

rated current: 30A / 725Hz
the chokes are rated at 725Hz but they have an adjustable airgap (about 0-5mm), so I guess at DC they should take still a few amperes though (for example as LC filter-network in power supplies for audio amplifiers).

Edgewound copper coil
DC-restistance: 50 milli-Ohm (mOhm)

w120mm x d107mm x h150mm (with connectors 185mm height)
6,3 kg / each (4 pcs. together 25,2kg!)

These chokes are old and the grey paint is worn off partly.
Also some of the plastic connectors on top are broken or missing but it should be no problem to replace them.


My asking price is Euro 15 each + shipping (Euro 12 inside Germany). I only sell all 4 together.

I ship anywhere but due to the weight the costs to ship outside Germany are probably prohibitive. I can accept PayPal with a 4% surcharge on the total to cover my fees.
