Hammond PWDP13160 Johnson Viking II HV Transformer, 865-0-865 VAC

The PWDP13160 is the Johnson Viking II high-voltage (HV) transformer, cross-referenced to SNC P/N #1781 and EFJ P/N 23.1002-1. It comes from the Peter W. Dahl design files in the PWDAHL Series and is aimed at restorers of the E.F. Johnson Viking II transmitter and technicians sourcing a replacement HV transformer.

The primary is rated 115 VAC at 60 Hz. The single secondary, S1, is a center-tapped 865-0-865 VAC winding rated 250 mA CCS.

The transformer is built on an EI-150 x 2 core in style 5 of the series style sheet, with an approximate weight of 10 lb. It is listed as REACH and RoHS compliant and carries UPC 623980474779.

The PWDP13160 primary is listed for 60 Hz, so buyers outside North America should note the series caution to pick 50/60 Hz parts if they need 50 Hz. PWDAHL Series units are usually built to order one at a time, and the series notes recommend confirming availability by phone or e-mail before ordering. The single center-tapped winding keeps the PWDP13160 a focused high-voltage part, with UNSPSC code 39121301 for procurement.
