FAQs
The transformer provides a three-phase 480 V primary and a 208Y/120 V secondary. This configuration supports standard industrial power distribution from medium-voltage mains to common low-voltage controls and machinery loads, simplifying panel design and reducing the need for additional voltage conversion gear.
The unit offers taps at +2.5% and -2.5%, enabling voltage adjustment to compensate for line drop, load variations, or long cable runs. This capability improves voltage stability for sensitive equipment and ensures consistent performance across changing facility conditions.
This transformer adheres to a low-noise NEMA TP-1 design with an approximate level of 47 dB, making it suitable for installation in or near control rooms, offices, and other noise-sensitive environments without compromising performance.
Warranty is Eaton’s Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. For installation, ensure proper mounting, ventilation, and compliance with listed voltage and cooling requirements to maximize reliability and service life.
With a 150 kVA three-phase rating, copper windings, 480 V to 208Y/120 V conversion, and a low-noise NEMA TP-1 profile, the transformer delivers reliable, efficient power with robust voltage regulation. It aligns with automation stack needs, supports drives and controls, and reduces the need for multiple step-down transformers.
