The 182T30 is a 750 VA low-voltage toroidal power transformer for chassis mounting, from the 182 Series. Its dual secondary delivers 60V C.T. @ 12.5A when the windings are connected in series, or 30V @ 25A when they are connected in parallel, making it a fit for OEM engineers and equipment builders who need a 60V centre-tapped or 30V supply from a single core.
The primary is a dual 117/234 VAC winding for 50/60 Hz operation: wire the two primary halves in parallel for 117 VAC or in series for 234 VAC. The manufacturer's short description for this part reads "REPLACED WITH 1182T30". The toroidal design is described as low profile, lightweight and cool running thanks to its high efficiency, and the units are designed to have all windings engaged. Flexible leads are a minimum of 8" long, and every unit is Hi-Pot tested at 4,000V RMS between primary and secondary.
Physically, the 182T30 measures 6.40 in (163 mm) in outside diameter and 3.10 in (79 mm) high, with a table weight of 13.53 lbs and a listed shipping weight of 13.5 lbs (6.12 kg). It uses center single-hole mounting through a potted center for extra mounting strength, and ships with one bottom rubber insulating pad and mounting hardware: a 3/8-16 center bolt 3.50 in (89 mm) long (bottom rubber washer only, no top steel washer).
The series is CSA certified to C22.2 #66 (CSA file #209651), UL recognized to UL506 (UL file #E207860) and CE certified to IEC950, and this part is listed as RoHS and REACH compliant. Because toroidal transformers can draw a high magnetizing inrush current when first energized, the manufacturer advises a slow-blow fuse, time-delayed circuit breaker or other soft-start circuitry on the supply line.
Note: the 182 Series will soon be discontinued as a stocked series and is available while quantities last. The manufacturer lists 1182T30 as the replacement for the 182T30, within the 1182 Series.

With the two secondary windings in series it provides 60V C.T. @ 12.5A; with them in parallel it provides 30V @ 25A.
Yes. It has a dual 117/234 VAC primary for 50/60 Hz operation: connect the primary windings in parallel for 117 VAC or in series for 234 VAC.
It uses center single-hole mounting through a potted center. It is supplied with one bottom rubber insulating pad and mounting hardware, a 3/8-16 bolt 3.50 in (89 mm) long.
Outside diameter is 6.40 in (163 mm) and height is 3.10 in (79 mm). The ordering table lists 13.53 lbs and the shipping weight is 13.5 lbs (6.12 kg).
Toroidal transformers can draw high magnetizing current when first energized, limited only by the primary's low DC resistance; the overload rarely lasts longer than half a cycle. A slow-blow fuse, time delayed breaker or soft start circuit is recommended.
The 182 Series will soon be discontinued as a stocked series and is available while quantities last. The manufacturer lists 1182T30 as the replacement.
