The 1182H18 is a toroidal power transformer constructed with class B material, featuring dual primary and dual secondary windings. It is compact, lightweight, and designed for efficient operation without excessive heating, resulting in high efficiency and low electromagnetic interference due to minimal magnetic flux diffusion. The transformer supports dual primary voltages of 117/234VAC at 50/60Hz, with flexible conductors at least 8 inches long. It has undergone dielectric testing at 4000VAC RMS between primary and secondary. This transformer complies with UL 506 (XPTQ2 Guide, No. E207860), CSA Standard C22.2 No. 66-209651, and conforms to IEC 61558-2-4 standards according to EC regulations. It is suitable for industrial applications and includes accessories such as rubber and steel mounting washers, a bolt with lockwasher, and a hex nut.
