The 1182U110P is a 1500 VA potted-center toroid power transformer with two 110 V secondaries. Series connection gives 220V C.T. @ 6.8A and parallel connection 110V @ 13.6A. With 1.90% listed regulation it is intended for high-power 110 V or 220 V outputs derived from 117 VAC or 234 VAC mains.
The drawing shows each secondary as 110V @ 6.80 A and specifies #12 TEW primary and secondary leads, 8"-9" long and stripped 0.5" minimum. The epoxy center is filled 0.50" from the top and drilled 13/32" for a 3/8 bolt; supplied hardware is one 0.125" x 6.00" OD rubber washer and one 3/8-16 bolt 4.00" long with lock washer and hex nut. Dimension reference is M. Shipping weight is 23 lbs (10.43 kg); the drawing lists 24.75 lbs +/- 4%.
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.
Ideal For
- 110 V or 220 V center-tapped outputs at 1500 VA
- Line-voltage isolation where a potted-center toroid is preferred
- Equipment for both 117 VAC and 234 VAC supplies (global use)
- Designs needing low stray magnetic flux (low EMI) in a low-profile package

Frequently Asked Questions
What outputs does the 1182U110P provide?▾
220V C.T. @ 6.8A with the secondaries in series or 110V @ 13.6A in parallel, at 1500 VA.
How is the 1182U110P mounted?▾
Through its potted epoxy center, drilled 13/32" for a 3/8 bolt, with the supplied 3/8-16 x 4.00" bolt, lock washer, hex nut and 0.125" x 6.00" OD rubber washer.
Why might the 1182U110P trip a breaker when switched on?▾
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 circuit breaker or soft-start circuitry is recommended on the supply line.
Is it UL and CSA approved?▾
The 1182 series is UL recognized to UL 5085-1 and UL 5085-2 (file #E207860) and CSA certified to C22.2 #66.1-6 and C22.2 #66.2-6 (file #209651).
How do I wire the primary for 117 V or 234 V?▾
Connect the two 117 V primaries (BLK-WHT and BRN-ORN) in parallel for 117 VAC or in series for 234 VAC, 50/60 Hz. A connection sheet is included with the transformer.
