277 VAC INPUT AC‑DC POWER SUPPLIES

Wide Input Models from 1 ~ 500 W

Wide Input Voltage Range Power Supplies

CUI's wide input (85 ~ 305 Vac) ac-dc power supplies are designed to support 277 Vac input voltages. 277 Vac is a product of 480 Vac three-phase power and these wide input range capable power supplies offer the convenience of tying directly into 277 Vac circuits without any additional power transformation minimizing both cost and complexity. This is useful for a variety of industrial, smart building, sensing, and lighting applications. This line of power supplies offers open frame, encapsulated, and metal case models ranging from 1 W to 500 W. Featuring efficiency levels as high as 90% and board mount, DIN rail, and chassis mounting options.
