Hammond 270DAZ 76 VA Horizontal Plate Transformer, 520V C.T. 104mA

The 270DAZ is the horizontal (Z) mounting version of a 76 VA high voltage (plate) and filament transformer. It takes a 117 VAC primary, listed at 60 Hz on the part page, and delivers a 520V center-tapped secondary at 104 mA plus a single 6.3V filament winding at 3.5A, for chassis layouts that call for a low, horizontally mounted part.

Electrically, the 270DAZ is rated 76 VA with a 117 VAC, 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. Its vertical-mount counterpart with the same winding ratings is the 270DAX; this Z-mount version has its own dimension set (A through J).

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 2.25 in (57 mm), B 2.88 in (73 mm), C 3.25 in (83 mm), D 1.88 in (48 mm), F 2.38 in (60 mm), G 1.25 in (32 mm), H 3.38 in (86 mm), J 2.81 in (71 mm). Shipping weight is 3.9 lbs (1.77 kg).

The 270DAZ 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 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.
