4812 - Aux (480-120 volt, 200 VA)
4812 - Aux (200 VA) - 480:120
This transformer is designed to provide auxiliary power where the application is 480V 3- wire delta, 480/240V 4-wire delta, or 480/277V 4-wire wye. Applications include, but are not limited to, external three-phase Landis+Gyr (Hunt) endpoints, modems, load management receivers, and other electronic equipment.

This transformer is similar in its basic design to the ones used in our 2:1 and 2.5:1 VT PacksTM (Cat. #s 6004824 & 6003012). The 4812-Aux provides the same protection against failure of the Landis+Gyr (Hunt) endpoint as the VT Pack™ provides against transient induced failure of wide voltage range solid state meters.
