AHR Series Class 2 UL 1585 Transformers
The AHR Series transformers are designed for efficient and reliable power conversion, offering a range of VA ratings from 30 VA to 75 VA. They are inherently energy-limited for 30-40 VA models and feature a compact frame size, low heat rise, and split bobbin design. These transformers are suitable for various input voltages (120-575 V) with a standard 24 V output, and offer flexible termination options including screw, quick-connect, or wire leads. Customization for wire length, color, and terminations is available. The 75 VA models include an integrated resettable circuit breaker and are non-inherently energy limited.
