Hammond PWDP13019 ARRL-003 Power Transformer, 46 lb

The PWDP13019 is listed on the manufacturer's part page under the short description ARRL-003. It is part of the PWDAHL Series, a listing of transformers and chokes taken directly from the Peter W. Dahl files of magnetics for amateur radio products, and its PWDP prefix places it with the power transformers in that listing.

The part page gives a shipping weight of 46 lbs (20.87 kg). PWDP13019 is marked REACH compliant and RoHS compliant, and is identified by UPC 623980240015 and UNSPSC 39121301.

Winding voltages, current ratings, primary frequency, core and style are not published on the part page for this part number. Builders following an ARRL-003 design, or anyone replacing this transformer, should confirm the electrical details with the manufacturer before ordering.

Buyers outside North America should also confirm the supply frequency, because the series notes that most Dahl parts are only listed for 60 Hz and a part must say 50/60 Hz for 50 Hz use. Dahl transformers are usually built to order one at a time, and units already built are shown with Hammond part numbers. The series recommends confirming availability by phone or e-mail; stock units can usually be shipped next business day.
