Step-Down Transformers - 347/480V to 277V
Step-down transformers are designed to utilize standard universal voltage (120-277V) electronic drivers and ballasts in applications where the main facility power is either 347V or 480V. These transformers can be used to operate multiple luminaires up to the rated maximum power, which is rated in volt-amps (VA).
▪ Operates at input voltage of either 347V or 480V (+ 10% voltage variations) at 60Hz.
▪ Output voltage is 277V (single phase).
▪ Non-isolated autotransformer.
▪ Sound rated A.
▪ Thermally protected.
▪ Lead lengths are 8” (30 & 70VA models) & 14” (250 & 375VA models.
