The PWDP13137 is a Peter W. Dahl design power transformer for the Drake AC-4 power supply, the supply used with the Drake "4" line including the T-4, T-4X and TR-4. It is intended for amateur radio operators and technicians keeping these stations on the air.
Unlike many parts in the series, the PWDP13137 primary is rated 120/240 VAC at 50/60 Hz, single phase, so the listing covers both 50 Hz and 60 Hz mains. Four secondaries are listed:
- S1: 265 VAC @ 750 mA CCS
- S2: 90 VAC @ 350 mA CCS
- S3: 95 VAC @ 100 mA CCS
- S4: 12.6 VAC @ 5.5 A CCS
The transformer is built on an EI-150 x 3 in. core of 29GAM6X laminations in style 2 of the series style sheet. Approximate weight is 14 lb, with a shipping weight of 14 lbs (6.35 kg). It is listed as REACH and RoHS compliant. Series units are usually built to order, so confirm availability before ordering. Because the primary is dual-voltage and dual-frequency, the same PWDP13137 can serve an AC-4 on 120 VAC or 240 VAC mains. Identifiers are UPC 623980436081 and UNSPSC 39121301.
