Product Description
AHR Series Class 2 UL 1585 Transformers
The AHR Series transformers are designed for reliable power conversion, offering a range of VA ratings from 30 VA to 75 VA. These Class 2 transformers are UL 1585 recognized and feature a split bobbin design for improved safety and performance. They are suitable for various applications requiring input voltages from 120V to 575V and a 24V output. Key advantages include compact frame size, low heat rise, and options for screw, quick-connect, or wire lead terminations. For 75 VA models, an integrated resettable circuit breaker is included.
