The 273DX is a 101 VA high voltage (plate) and filament transformer with a 117 VAC primary rated for 50/60 Hz. It supplies a 700V center-tapped high voltage secondary (350-0-350) at 103 mA, a 5V @ 2A winding and a center-tapped 6.3V filament winding at 3A, in the vertical (X) mounting style.
Electrically, the 273DX is rated 101 VA with a 117 VAC, 50/60 Hz primary, a high voltage secondary rated 700V C.T. @ 103mA (RMS), and filament windings of 5V @ 2A (#1) and 6.3V C.T. @ 3A (#2). As with every 200 Series unit, it can be run full wave bridge or full wave C.T. The 273DZ carries the same winding ratings in a horizontal (Z) mount; the 273DX case is 2.88 in by 3.50 in, a size listed for no other part in this group.
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 2.88 in (73 mm), B 3.50 in (89 mm), C 3.50 in (89 mm), D 2.25 in (57 mm), F 2.44 in (62 mm), with 0.20 in (5 mm) x 0.38 in (10 mm) mounting slots. Shipping weight is 4.6 lbs (2.09 kg).
Its primary is listed at 117 VAC, 50/60 Hz, so it is one of the 200 Series parts suited to both 50 Hz and 60 Hz supplies. 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.
