Hammond PWDP13078 1650/1515/1375 VAC C-Core Power Transformer

The PWDP13078 is a Peter W. Dahl power transformer designed for the 2000 volt supply described in the ARRL Handbook. It is intended for amateur radio builders constructing a high-voltage amplifier supply to that design.

The tapped secondary is rated 0-1375-1515-1650 VAC @ 1.2A CCS, giving 1650, 1515 or 1375 V selections from one winding. The primary is 234 VAC 60 Hz single phase.

It is wound on an A-0480 C-core in Style 10 and weighs approximately 46 lbs. The series notes that some Hipersil C-core models in Styles 8, 9 and 10 need to be quoted by the manufacturer's office, so pricing and lead time for this unit should be confirmed directly.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980186092. Shipping weight is 46 lbs (20.87 kg).

The PWDP13078 is listed in the PWDAHL Series of transformers and chokes taken directly from the Peter W. Dahl files, a range described as magnetics for amateur radio products. These transformers are usually built to order one at a time, and because many of the designs are decades old it is always best to confirm availability by phone or e-mail before planning a repair around it. Units that have already been built are shown with Hammond part numbers, as this one is, and stock units can usually be shipped the next business day.
