The 165P25 is a 125VA 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 25.0 VAC (R.M.S.) center tapped at 5 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 165P25 measures A 3.00 in (76 mm), B 3.25 in (83 mm), C 2.56 in (65 mm), D 2.50 in (64 mm), E 3.25 in (83 mm) and F 4.00 in (102 mm), with 0.22 in x 0.56 in mounting slots. Shipping weight is 5 lbs (2.27 kg).
The series is UL listed (# E207860) Type 3AH and CSA certified (# LR209651), and the 165P25 is listed as RoHS and REACH compliant.
