The 165U18 is a 270 VA low-voltage, high-current transformer that steps a 115 VAC, 60 Hz single primary down to 18.0 V center-tapped RMS at 15 A. It serves OEM engineers and technicians who need an 18 V C.T. winding with more current than the 10 A 165S18 but less than the 20 A 165V18.
Construction follows the 165 Series design: an open-style, four-hole frame for chassis mounting, a dual bobbin winding arrangement that needs no electrostatic shield, and Class B insulation rated 130 degrees C. Connections are made through minimum 6 in long leads or copper tabs with holes, and every unit is Hi-Pot tested at 2,000 V RMS.
The 165U18 moves up to the larger 165 Series frame: dimension A is 4.50 in (114 mm), B is 3.88 in (99 mm), C and D are 3.75 in (95 mm), E is 2.75 in (70 mm) and F is 3.50 in (89 mm). The mounting slot is 0.28 in x 0.56 in, and the unit ships at 9 lbs (4.08 kg).
- Power rating: 270 VA
- Secondary: 18.0 V C.T. (RMS) at 15 A
- Primary: 115 VAC, 60 Hz single primary
- Mounting slot: 0.28 in x 0.56 in
The 165 Series is UL listed (file E207860, Type 3AH) and CSA certified (LR209651). The 165U18 is also listed as RoHS compliant and REACH compliant, and is identified by UPC 623980218601 and UNSPSC code 39121301.
