Hammond 266J36 36VA Transformer, 36V C.T. or 18V Parallel Output

The 266J36 is a 36 VA dual-primary, dual-secondary power transformer that gives a 36 V center-tapped output at 1 A or 18 V at 2 A in parallel, suited to chassis-mounted low-voltage supplies in OEM and repair work. It belongs to the Hammond 266 Series of low voltage/filament transformers and is aimed at OEM engineers, repair technicians and panel builders who mount the transformer directly to a chassis.

The primary is a dual 117/234 VAC, 50/60 Hz winding: connect the two primary halves in parallel for 117 V or in series for 234 V. The dual secondaries can be used as a center-tapped secondary (36V @ 1A), connected in parallel (18V @ 2A) or used individually, and the unit is designed for use with all windings engaged.

Construction is open style with a dual bobbin design, so no electrostatic shield is required. Hammond uses Class B (130 °C) insulation for extra protection, while the design is UL listed as Class A (105 °C). Every unit is hi-pot tested at 2,000V RMS, and all leads are a minimum of 6 in long. The transformer is UL listed (# E207860) Type 3AH, CSA certified (209651), and RoHS and REACH compliant.

The 266J36 uses mounting style A with 0.19 in (5 mm) mounting holes. Its listed dimensions are A 3.69 in (94 mm), B 1.97 in (50 mm), C 2.31 in (59 mm) and D 3.13 in (80 mm). It weighs 1.78 lbs (0.81 kg) and ships at 1.6 lbs (0.73 kg).
