The PWDP13148 is the Palomar 300A power transformer, built from the Peter W. Dahl design files in the PWDAHL Series. It is intended for owners and repair technicians of Palomar 300A amateur radio equipment who need a replacement power transformer.
The primary is 117 VAC, 60 Hz, single phase. Two secondaries are listed: S1 delivers 310 VRMS at 1.0 A CCS, and S2 delivers 14 VRMS at 8 A CCS.
The transformer is wound on an EI-150 x 2 1/2 in. core and built in style 5 of the series style sheet. Its shipping weight is 14 lbs (6.35 kg). It is listed as REACH and RoHS compliant, with UPC 623980474632.
Because the PWDP13148 is specified for a 60 Hz primary, buyers on 50 Hz supplies should take note of the series guidance to select parts marked 50/60 Hz. PWDAHL transformers are usually built to order one at a time; the series notes recommend confirming availability by phone or e-mail before ordering. The two windings make the PWDP13148 a straightforward two-secondary design: one 310 VRMS supply winding and one 14 VRMS winding rated for 8 A continuous. Its UNSPSC code is 39121301.
