The 167U7 is a low voltage, filament-type power transformer from the 167 Series, in an enclosed, chassis mount package with a 115 VAC, 60 Hz primary. It is rated 112.5 VA and delivers a 7.5 V centre-tapped secondary (RMS) at 15 A, for OEM engineers, equipment builders and repair technicians who need a fixed low-voltage AC secondary from a 115 V line. The 167U7 delivers 7.5 V centre-tapped at 15 A, rated 112.5 VA (113VA in its short description).
The 167 Series uses a dual bobbin design, so no electrostatic shield is required. Insulation is Class B (130 degrees C), units are hi-pot tested at 2,000 V RMS, and every secondary in the series is centre tapped. Leads are a minimum of 6 in long, and the series is UL listed (# E50394) and CSA certified (209651).
Per the series ordering table, the 167U7 measures A 2.50 in (64 mm), B 3.25 in (83 mm) and C 3.06 in (78 mm), with D 2.00 in (51 mm) and E 2.19 in (56 mm). Its mounting slots (G) are 0.20 in (5 mm) x 0.38 in (10 mm), used with the enclosed four-hole chassis mount. Shipping weight is 3.7 lbs (1.68 kg).
The 167U7 is listed as RoHS compliant and REACH compliant, with UPC 623980237701 and UNSPSC 39121301.
