Hammond PWDP13003 National NCX-1000 Plate Power Transformer

The PWDP13003 is a power transformer for the National NCX-1000, supplying the plate, driver plate and screen voltages. It comes from the Peter W. Dahl files of magnetics for amateur radio products and suits NCX-1000 owners and restorers who need to replace the transformer feeding the high-voltage stages of the transceiver.

The primary is 117/234 VAC 60 Hz, single phase. The secondaries are S1 1100 VAC at 0.36A CCS and S2 0-240-480 VAC at 0.20A CCS.

PWDP13003 is built on an EI-175 x 2.5 lamination core in Style 2 of the series style sheet. The approximate weight is 17 lbs and the part page shipping weight is 17 lbs (7.71 kg). It is marked REACH compliant and RoHS compliant, with UNSPSC 39121301.

Because the primary is listed for 60 Hz only, buyers outside North America should heed the series note that a part must say 50/60 Hz for 50 Hz use. Dahl-series transformers are usually built to order one at a time, and units already built are shown with Hammond part numbers. The series recommends confirming availability by phone or e-mail; stock units can usually be shipped next business day.
