The Iso-Care and NRT (Noise Reduction Transformer) are three-phase, delta to wye isolation transformers designed for
isolation with optional distribution of AC power.
The Iso-Care and NRT can accommodate input voltages 208 or 480 VAC +5% and -10%, and output voltages 208Y/120 or
480Y/277. The input frequency range of the Iso-Care is 50 to 60 Hz. The NRT is designed for 60 Hz only.
The model number along with the input and output voltages are provided on the label plate located on the front of the unit.
All components used are of the highest quality and specifically selected to achieve the highest level of performance. The Iso-
Care and NRT transformers are UL listed and the units are certified by UL Laboratory Inc. in accordance with IEC Pub 601-
1. The Iso-Care and NRT conforms to National Electric Code (NEC) and Occupational Safety and Health Act (OSHA)
