- 7.5 V center-tapped RMS secondary rated 21 A
- 157.5 VA power rating from a 115 VAC, 60 Hz single primary
- Open-style four-hole frame for chassis mounting
- Dual bobbin design; no electrostatic shield required
- Class B insulation (130 degrees C) and 2,000 V RMS Hi-Pot test

- UL listed (E207860) Type 3AH and CSA certified (LR209651)
- RoHS and REACH compliant
The 165V7 is a 157.5 VA chassis-mount power transformer that converts a 115 VAC, 60 Hz single primary into 7.5 V center-tapped RMS at 21 A. It fills the gap between the 5 V and 10 V models in the 165 Series for engineers who need a 7.5 V C.T. winding at more than 20 A.
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.
Hammond's short description for the 165V7 rounds the rating to 158 VA (FIL RECT 158VA 115 7.5CT), while the part page and ordering table list the exact 157.5 VA. The frame measures 3.75 in (95 mm) at dimension A and 2.63 in (67 mm) at dimension B, and the unit ships at 5.5 lbs (2.49 kg).
- Power rating: 157.5 VA
- Secondary: 7.5 V C.T. (RMS) at 21 A
- Primary: 115 VAC, 60 Hz single primary
- Mounting slot: 0.22 in x 0.56 in
The 165 Series is UL listed (file E207860, Type 3AH) and CSA certified (LR209651). The 165V7 is also listed as RoHS compliant and REACH compliant, and is identified by UPC 623980215907 and UNSPSC code 39121301.
