The 165S18 is a 180VA low voltage, high current power transformer for chassis mounting, from the 165 series of filament transformers. It runs from a single 115 VAC, 60 Hz primary and delivers 18.0 VAC (R.M.S.) center tapped at 10 amps, making it a fit for equipment builders, panel shops and repair technicians who need a heavy-current low voltage secondary with a center tap.
Construction is an open style, 4 hole frame chassis mount with a dual bobbin design, so no electrostatic shield is required. Connections are made through leads a minimum of 6 in long or copper tabs with holes. Insulation is Class B (130 degrees C) and the series is hi-pot tested at 2,000V RMS.
Per the series dimension table, the 165S18 measures A 3.75 in (95 mm), B 3.13 in (80 mm), C 3.13 in (80 mm), D 3.13 in (80 mm), E 2.75 in (70 mm) and F 3.50 in (89 mm), with 0.22 in x 0.56 in mounting slots. Shipping weight is 6 lbs (2.72 kg).
The part drawing identifies the primary as the two BLK leads and the 18VCT secondary as GRN - GRN with a GRN/YEL center tap. All leads come out at least 6 in and are stripped 0.5 in. Test data on the drawing lists a no-load secondary of 19.38V across the full winding.
The series is UL listed (# E207860) Type 3AH and CSA certified (# LR209651), and the 165S18 is listed as RoHS and REACH compliant.
Ideal For
