Hammond 269GX 48 VA Plate & Filament Transformer, 450V C.T.

The 269GX is a compact 48 VA high voltage (plate) and filament transformer from the 200 Series, built for a North American 115 VAC, 60 Hz primary. It pairs a 450V center-tapped high voltage secondary rated at 75 mA with a single 6.3V filament winding rated at 2.5A, which makes it a fit for builders and OEM engineers who need a modest plate supply and one filament rail from one small chassis-mount part.

Electrically, the 269GX is rated 48 VA with a 115 VAC, 60 Hz primary, a high voltage secondary rated 450V C.T. @ 75mA (RMS), and a single filament winding of 6.3V @ 2.5A. As with every 200 Series unit, it can be run full wave bridge or full wave C.T. Among the single-filament 269 models it sits between the 380V 269EX and the 500V 269JX, sharing their 2.19 in x 2.63 in footprint class.

The case is an enclosed, 4 hole, chassis mount design in the vertical (X) mounting style, with minimum 6 in long leads. Listed dimensions are A 2.19 in (56 mm), B 2.63 in (67 mm), C 2.63 in (67 mm), D 1.75 in (44 mm), F 1.56 in (40 mm), with 0.19 in (5 mm) x 0.25 in (6 mm) mounting slots. Shipping weight is 1.9 lbs (0.86 kg).

For the primary, the 200 Series wiring notes describe two choices: use the white and gray wires and tape the black wire for 115 VAC input, or use the white and black wires and tape the gray wire where roughly 125V line voltage is producing too high a secondary voltage. Never connect power to both the gray and black wires at once. Insulation is Class A (105 degrees C), units are hi-pot tested at 2,000V RMS, the design is CSA certified (209651), and the part is RoHS and REACH compliant.
