Q217U-2 by Danaher

The Danaher Q217U-2 is a versatile variable transformer from the POWERSTAT Transformers series designed for industrial automation and power conditioning applications. Featuring a dual-input voltage configuration of 480V or 240V, it simplifies integration across multiple grid standards and reduces the need for external voltage converters. With an astonishing frequency range of 60-1500 Hz, the Q217U-2 accommodates both conventional utility supplies and high-frequency power sources, making it ideal for pulse-modulated AC systems and variable-frequency drives.

This transformer supports both single-phase and three-phase topologies through its #2 1-Phase Series and #2 3-Phase Open Delta connection types. The input is selectable between 480V and 240V, and the programmable output spans 0–480V (1-Phase) and 0–240V (3-Phase) via a precision winding tap system. It delivers a maximum constant current load output of 5.0 Amps for continuous operation, extending to 5.5 Amps at 480V or 7.0 Amps at 240V under constant impedance loads. Power ratings range from 2.1–3.4 kVA (constant current) and 2.9–3.5 kVA (constant impedance), ensuring reliable performance under varying load conditions.

Built for demanding industrial environments, the Q217U-2 sustains a maximum allowable output current of 6.3 Amps while maintaining thermal stability and controlled magnetic flux density. Its robust electromagnetic core construction minimizes hysteresis and eddy currents, enhancing efficiency across a broad frequency spectrum. The transformer’s advanced insulation system withstands rapid field cycling and voltage transients, promoting long service life with minimal maintenance. By offering precise, programmable voltage control and durable performance, the Q217U-2 delivers enhanced power quality, reduced downtime, and unmatched flexibility for global automation projects.
