Hammond 273CZ 159 VA Horizontal Plate Transformer, 650V C.T. 172mA

The 273CZ is a 159 VA high voltage (plate) and filament transformer in the horizontal (Z) mounting style, with a 117 VAC primary rated for 50/60 Hz. It provides a 650V center-tapped secondary (325-0-325) at 172 mA, a 5V @ 3A winding and a center-tapped 6.3V filament winding at 5A.

Electrically, the 273CZ is rated 159 VA with a 117 VAC, 50/60 Hz primary, a high voltage secondary rated 650V C.T. @ 172mA (RMS), and filament windings of 5V @ 3A (#1) and 6.3V C.T. @ 5A (#2). As with every 200 Series unit, it can be run full wave bridge or full wave C.T. It is the higher-power 650V C.T. horizontal option; the 273AZ offers the same 650V C.T. rating at 49 VA and 46 mA.

The case is an enclosed, 4 hole, chassis mount design in the horizontal (Z) mounting style, with minimum 6 in long leads. Listed dimensions are A 2.50 in (64 mm), B 3.13 in (80 mm), C 3.81 in (97 mm), D 2.00 in (51 mm), F 2.69 in (68 mm), G 1.33 in (34 mm), H 3.75 in (95 mm), J 3.13 in (80 mm). Shipping weight is 5.9 lbs (2.68 kg).

The 273CZ is a Z-mount part, and the series notes state that most Z mounts do not use the 115V/125V primary choices offered on other 200 Series units, so check the part drawing for its available primary voltages; the listed primary is 117 VAC at 50/60 Hz. 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.
