Hammond PWDF13181 Central Electronics 600L Multiple Filament Transformer

PWDF13181 is a multiple-winding filament transformer for the Central Electronics 600L, cross-referenced in the ordering table to Chicago 25077. It is catalogued in Hammond's PWDAHL Series of magnetics for amateur radio products, reproduced directly from the Peter W. Dahl files, and is aimed at 600L owners and restoration technicians.

From a 120 VAC, 60 Hz, single-phase primary, it provides six secondaries:

• S1: 240 VAC @ 0.015 A
• S2: 10 VCT @ 5 A CCS
• S3: 6.3 VAC @ 0.45 A CCS
• S4: 6.3 VAC @ 0.3 A CCS
• S5: 2.5 VCT @ 4 A CCS (2,500 VDC insulation)
• S6: 6.3 VCT @ 4 A CC

The S5 winding carries 2,500 VDC insulation. As a 60 Hz part, it is covered by the series advice that buyers needing 50 Hz should choose a part marked 50/60 Hz.

The transformer uses an EI core and is Style 4 on the series style sheet. The approximate weight is 10 lbs and the shipping weight is 10 lbs (4.54 kg). PWDF13181 is REACH compliant and RoHS compliant, with UPC 623980436050 and UNSPSC 39121301. PWDAHL units are usually built to order one at a time, so Hammond recommends confirming availability by phone or e-mail.
