Hammond 266T6 75VA 6V CT / 3V @ 25A Filament Transformer

The 266T6 is a 75VA low voltage power transformer rated 6V @ 12.5A with a center tap, or 3V @ 25A with its secondaries in parallel. It is part of the 266 Series of open style, chassis mount transformers with a dual 117/234 VAC, 50/60 Hz primary.

The 25A parallel rating at 3V suits high-current, very low voltage loads; the 266T6 uses Style B mounting and weighs 6.4 lbs.

Each unit has a dual 117/234 VAC, 50/60 Hz primary (wired in parallel for 117V, in series for 234V) and dual secondaries that can be used as a center tapped secondary, connected in parallel, or used individually. The 266T6 is designed for use with all windings engaged. Primary leads are Blk, Wht, Brn and Orn; secondary leads are Red, Blu, Gry and Yel, all at least 6" long.

It uses Mounting Style B with mounting holes 0.20 in (5 mm) high by 0.38 in (10 mm) wide. Listed dimensions are A 3.13 in (80 mm), B 3.56 in (90 mm), C 3.81 in (97 mm), D 2.50 in (64 mm), E 3.00 in (76 mm). Unit weight is 6.4 lbs, with a shipping weight of 6.4 lbs (2.90 kg).

Construction uses a dual bobbin design, so no electrostatic shield is required, and Class B insulation (130 °C), while the unit is UL listed as a Class A (105 °C) design. It is hi-pot tested at 2,000V RMS, UL listed (# E207860) Type 3AH, CSA certified (209651), and RoHS and REACH compliant.
