Hammond 270CAX 65 VA 50/60 Hz Plate Transformer, 500V C.T. 81mA

The 270CAX is a 65 VA high voltage (plate) and filament transformer with a 117 VAC primary rated for 50/60 Hz, one of the few 200 Series parts listed for both line frequencies. Its 500V center-tapped secondary is rated at 81 mA (listed in the short description as 250-0-250), and it adds a 5V @ 2A winding and a 6.3V @ 2.5A filament winding.

Electrically, the 270CAX is rated 65 VA with a 117 VAC, 50/60 Hz primary, a high voltage secondary rated 500V C.T. @ 81mA (RMS), and filament windings of 5V @ 2A (#1) and 6.3V @ 2.5A (#2). As with every 200 Series unit, it can be run full wave bridge or full wave C.T. The manufacturer's short description identifies the 6.3V winding as center-tapped (6.3VCT@2.5A).

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 2.06 in (52 mm), with 0.20 in (5 mm) x 0.38 in (10 mm) mounting slots. Shipping weight is 3.2 lbs (1.45 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.
