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. They are inherently energy-limited for 30-40 VA models and feature integrated resettable circuit breakers for 75 VA models. These transformers boast a compact frame size, low heat rise, and a split bobbin design for efficient operation. They are suitable for various input voltages (120-575 V) with a standard 24 V output and offer flexible termination options including screw, quick-connect, and wire leads. Customization for wire length, color, and terminations is available. Certified to UL/CUR standards, these transformers are ideal for applications requiring Class 2 safety and compliance with UL 1585.
