Hammond PWDP13108 Modified Globe King 500B Plate Transformer

The PWDP13108 is a modified Peter W. Dahl plate transformer for the Globe King 500B transmitter. The ordering table lists it for a 1800 VDC @ 400 MA CCS supply with a full-wave bridge (FWB) and choke input.

The difference from the standard PWDP13074 is the primary: this modified version has a 120/240 VAC 60 Hz single-phase primary, rather than 115 VAC. The ordering table does not list a separate secondary rating for this part.

It uses an EI-175 X 5 lamination core in Style 5 and weighs approximately 31 lbs.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980930589. Shipping weight is 31 lbs (14.06 kg).

The PWDP13108 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.
