Hammond 266P24 120VA 24V CT Dual-Secondary Power Transformer

The 266P24 is a 120VA chassis mount power transformer with dual secondaries rated 24V @ 5A in series with a center tap, or 12V @ 10A in parallel. Its dual primary is wired for 117V or 234V, 50/60 Hz, and it is built open style like the rest of the 266 Series.

The 266P24 steps up from the 96VA 266N24 to 120VA at the same 24V/12V voltages, giving 5A and 10A respectively; it weighs 5.2 lbs (2.36 kg).

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 266P24 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 2.86 in (73 mm), C 3.81 in (97 mm), D 2.50 in (64 mm), E 2.50 in (64 mm). Unit weight is 5.2 lbs (2.36 kg), with a shipping weight of 4.2 lbs (1.91 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.
