The 270DAX is a 76 VA high voltage (plate) and filament transformer with a 117 VAC primary rated for 50/60 Hz operation. It supplies a 520V center-tapped high voltage secondary at 104 mA and a single 6.3V filament winding at 3.5A, in the vertical (X) mounting style.
Electrically, the 270DAX is rated 76 VA with a 117 VAC, 50/60 Hz primary, a high voltage secondary rated 520V C.T. @ 104mA (RMS), and a single filament winding of 6.3V @ 3.5A. As with every 200 Series unit, it can be run full wave bridge or full wave C.T. A horizontal (Z) version with the same 76 VA, 520V C.T. @ 104 mA and 6.3V @ 3.5A ratings is listed as the 270DAZ.
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 2.50 in (64 mm), B 3.00 in (76 mm), C 3.13 in (80 mm), D 2.00 in (51 mm), F 2.19 in (56 mm), with 0.20 in (5 mm) x 0.38 in (10 mm) mounting slots. Shipping weight is 3.5 lbs (1.59 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.
