The 1391-T100DT isolation transformer from Allen Bradley serves a critical role in protecting servo drive systems. This unit converts primary voltages ranging from 240 VAC to 480 VAC, providing flexibility for different installation environments. Rated for 10 kVA apparent power, it is designed to handle significant loads. The transformer features a secondary output voltage of 230 VAC delivered through single-phase CT windings.

Dissipation of power is capped at 500 W when operating under full load conditions, ensuring thermal management is adequate to prevent overheating. With an operating temperature range extending from 0 to 60 degrees Celsius, this transformer can function effectively in a variety of settings and applications. Furthermore, its storage temperature tolerance extends from 0 to 65 degrees Celsius, making it adaptable to various conditions when not in use.

In its core functionality, the 1391-T100DT acts as a safety barrier, mitigating risks associated with connecting the power source directly to a servo drive. This crucial feature enhances operational safety and efficiency, ensuring the drive receives stable power while protecting it from electrical disturbances.
