The PWDP13135 is a Peter W. Dahl design power transformer for the Heath HP-23A or HP-23B power supply. Heath HP-23 supplies are common companions to vintage amateur transceivers, and this part gives restorers and technicians a new-build transformer to put one back in service.
The primary is dual-voltage 120/240 VAC, 60 Hz, single phase. Three secondaries are listed: S1 at 282 VAC @ 0.25 A CCS, S2 a tapped 0-95-125 VAC @ 0.1 A CCS winding, and S3 at 12.6 VCT @ 6 A CCS.
Construction uses an EI-137 x 2.5 in. core of 29GM6X laminations, built in style 6 of the series style sheet. The approximate weight is 10 lb and the shipping weight is 10 lbs (4.54 kg). The part is listed as REACH and RoHS compliant.
The PWDP13135 is listed for 60 Hz operation. The series notes remind buyers outside North America that most parts are 60 Hz only and to look for 50/60 Hz if needed. PWDAHL units are usually built to order one at a time, so confirm availability by phone or e-mail. Identifiers for ordering are UPC 623980284194 and UNSPSC 39121301.
