The 182L30 is a 120 VA low-voltage toroidal power transformer from the 182 Series, built for chassis mounting in equipment where a low-profile, lightweight and cool-running transformer is needed. It suits OEM engineers, electronics designers and maintenance teams who need a dual 117/234 VAC primary for 50/60 Hz operation feeding dual secondaries that deliver 60V center-tapped at 2 A when wired in series, or 30V at 4 A when wired in parallel.
Both the primary and the secondary windings can be connected in series or parallel. Wire the primary in parallel for 117 VAC or in series for 234 VAC; wire the secondaries in series for 60V C.T. (center-tapped) or in parallel for 30V. The units are designed to have all windings engaged, and the flexible leads are a minimum of 8 in long.
The toroid measures 3.98 in (101 mm) in outside diameter and 1.68 in (43 mm) high, with a listed weight of 2.84 lb and a shipping weight of 2.8 lbs (1.27 kg). It has an open center and mounts through a single center hole using the included 10-24 hardware, 2.00 in (51 mm) long, supplied with two rubber insulating pads, one metal centering washer and all mounting hardware.
Each unit is Hi-Pot tested at 4,000 V RMS between primary and secondary. The series is CSA certified to C22.2 #66 (CSA file #209651), UL recognized to UL 506 (UL file #E207860) and CE certified to IEC 950, 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 recommends a slow-blow fuse, time-delayed circuit breaker or soft-start circuitry on the supply line.
Availability note: the 182 Series is being discontinued as a stocked series and is available while quantities last; it has been replaced by the 1182 Series, and the manufacturer lists 1182L30 as the replacement for the 182L30.

Wired in series, the dual secondaries give 60V C.T. (center-tapped) at 2 A; wired in parallel they give 30V at 4 A. The rating is 120 VA.
The primary is dual 117/234 VAC for 50/60 Hz operation: wire the primary windings in parallel for 117 VAC or in series for 234 VAC.
It mounts through a single center hole with included 10-24 hardware, 2.00 in (51 mm) long, and is supplied with two rubber insulating pads, one metal centering washer and all mounting hardware. The toroid has an open center.
It measures 3.98 in (101 mm) outside diameter by 1.68 in (43 mm) high and weighs 2.84 lb; the shipping weight is 2.8 lbs (1.27 kg).
Toroidal transformers can draw high magnetizing current when first energized, limited only by the primary's low DC resistance, usually for no longer than half a cycle. A slow-blow fuse, time delayed circuit breaker or soft-start circuit is recommended.
The 182 Series is being discontinued as a stocked series and is available while quantities last. It has been replaced with the 1182 Series; the listed replacement for this part is 1182L30.
