Hammond PWDP13023 Swan 117-XC Power Transformer, 117 VAC Primary

PWDP13023 is a replacement Swan 117-XC power transformer built for the Swan 350 AC power supply. It comes from the Peter W. Dahl transformer files, a collection of magnetics for amateur radio products, and suits restorers and service technicians rebuilding the Swan 350 AC power supply.

The transformer has a single 117 VAC, 60 Hz, single-phase AC primary. Four secondaries are specified, all rated CCS: S1 is a tapped 0-9.6-14.4-19.2 VAC winding at 6 A (marked DC PRI in the listing), S2 delivers 427 VAC at 300 mA, S3 delivers 230 VAC at 300 mA and S4 delivers 90 VAC at 140 mA.

It is wound on an EI-150 X 2 laminated core and is listed as Style 4 on the series transformer style sheet. Approximate weight is 10 lbs, with a shipping weight of 10 lbs (4.54 kg).

The primary is listed for 60 Hz only, so buyers outside North America should check their mains frequency before selecting this part; a 117/234 VAC 50/60 Hz version of the Swan supply transformer is listed separately in the series as the 230-XC. The part is REACH and RoHS compliant.

Like most Peter W. Dahl designs, PWDP13023 is usually built to order one at a time, so it is recommended to confirm availability by phone or e-mail before planning a repair.
