Hammond 167V22 440VA Enclosed Transformer, 22V Center-Tap 20A

The 167V22 is a 440 VA member of the 167 Series of low voltage, filament and rectifier transformers, listed as FIL-RECT 440VA 115 22VCT. It takes a 115 VAC, 60 Hz primary and supplies 22 V center-tapped RMS at 20 A, suiting integrators and OEM designers who need a high-power, low voltage winding for rectified DC rails or heater circuits.

The enclosed body is secured with a four-hole chassis mount. Internally, a dual bobbin design separates windings so that no electrostatic shield is required; insulation is Class B (130 degrees C) and each unit is Hi-Pot tested at 2,000 V RMS. Leads are a minimum of 6 inches long.

• A: 3.75 in (95 mm)
• B: 5.00 in (127 mm)
• C: 4.56 in (116 mm)
• D: 3.00 in (76 mm)
• E: 3.81 in (97 mm)
• Mounting slot G: 0.20 in (5 mm) x 0.38 in (10 mm)

Shipping weight is 13.6 lbs (6.17 kg), so mount it to a rigid chassis panel. The lettered dimensions follow the 167 Series drawing, and the center tap on the 22 V winding provides a mid-point reference for full-wave centre-tapped rectifier circuits. The 167V22 is UL listed (E50394), CSA certified (209651), and listed as RoHS and REACH compliant.
