Hammond 1182T30P 750 VA Potted-Center Toroid, 60V CT or 30V Output

The 1182T30P is the potted-center version of the 750 VA, 30 V toroid in the 1182 series. Its dual secondaries deliver 60V C.T. @ 12.5A in series or 30V @ 25A in parallel, and its dual 117 V primaries accept 117 VAC or 234 VAC.

The series ordering table lists the 1182T30P with a potted toroid center, 3.10% regulation and dimension reference K; the part page rounds regulation to 3%. Shipping weight is 13 lbs (5.90 kg). Electrically it matches the open-center 1182T30, so the choice between the two comes down to the center construction your mounting approach needs. Leads are flexible and a minimum of 8" long, as across the series.

On compliance, the 1182 family carries UL recognition to UL 5085-1 and UL 5085-2 under file #E207860 and CSA certification to C22.2 #66.1-6 and #66.2-6 under file #209651, and is self-declared as evaluated to applicable sections of IEC/EN61558-1 and IEC/EN61558-2-4. Windings use Class B (130 degree C) materials, primary-to-secondary insulation is hi-pot tested at 4,000 VAC RMS, and the part is listed as RoHS and REACH compliant.

The dual primary accepts 117 VAC (parallel connection) or 234 VAC (series connection) at 50/60 Hz, with a connection sheet included. Units are designed to run with every winding engaged, in series or parallel, or as an autotransformer. Plan the supply protection for toroidal inrush: the magnetizing current at energization is limited only by the primary's low DC resistance, so a slow-blow fuse, time-delayed breaker or soft-start is recommended.
