Hammond 266M24 72VA 24V Center-Tapped Open Style Transformer

The 266M24 is a 72VA chassis mount power transformer that turns a 117V or 234V, 50/60 Hz line into a 24V center-tapped secondary at 3A, or 12V at 6A. It belongs to the 266 Series of open style, dual primary and dual secondary low voltage transformers.

The 24V/12V pairing makes the 266M24 a flexible choice where a design may need either a 24V C.T. winding or a heavier 12V supply from the same footprint.

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 266M24 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 A with a 0.19 in (5 mm) mounting hole width. Listed dimensions are A 4.03 in (102 mm), B 2.50 in (64 mm), C 2.63 in (67 mm), D 3.56 in (90 mm). Unit weight is 2.68 lbs (1.22 kg), with a shipping weight of 2.6 lbs (1.18 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.
