Hammond 167L36 36V CT 2A Enclosed Chassis Transformer, 72 VA

The 167L36 is a 72 VA enclosed power transformer delivering 36 V centre-tapped at 2 A from a 115 VAC, 60 Hz primary. It suits split 18 V rectified supplies in amplifiers, control electronics and OEM products, and its drawing publishes electrical acceptance data for incoming inspection.

It follows the 167 Series construction: an enclosed housing, a dual bobbin design that needs no electrostatic shield, Class B insulation rated 130 °C, and a hi-pot test of 2,000V RMS. All secondaries in the series are centre tapped, and leads are a minimum of 6 in long (the drawing for this part specifies 8 in minimum, stripped 0.5 in). Per the drawing, secondary no-load voltage is 39.50 V ±2% across GRN - GRN (19.75 V ±2% to the GRN/YEL centre tap), and primary excitation current is 160 mA maximum.

The ordering table lists the 167L36 at A 2.50 in (64 mm), B 2.75 in (70 mm), C 3.06 in (78 mm), D 2.00 in (51 mm) and E 1.69 in (43 mm), with 0.20 x 0.38 in (5 x 10 mm) mounting slots for its 4 hole chassis mount. Shipping weight is 2.4 lbs (1.09 kg).

Drawing acceptance data at 20 °C gives a primary DC resistance of 5.861 ±20% (BLK - BLK) and a secondary DC resistance of 0.769 ±20% (GRN - GRN); the primary leads are black, the secondary leads green, and the centre tap green/yellow. The hi-pot test is 2000V, 60Hz for 1 second, primary to secondary.

The transformer is UL listed (# E50394) and CSA certified (209651), and it is declared RoHS and REACH compliant. Confirm your supply matches the 115 VAC, 60 Hz primary before installing.
