Description

The AS-XFR Series Transformer Module is a UL Class 2 device used to power digital controllers and input/output loads. It provides 120 VAC to 24 VAC isolation. Three different models are available (see selection chart below), all of which include a split-bobbin for added noise immunity and a manually resetable breaker on the secondary connection. The secondary connection includes a modular connector for use with AHU controllers and Companion products. Ground wires are electrically and mechanically connected to the transformer frame.

The XFR100 is a 100 VA transformer pre-mounted in an EN-ENC100 enclosure. It includes a power switch and a utility outlet. The enclosure can be vertically mounted with a DIN rail or directly mounted to a wall, and supports multiple 3/4 in. and 1-1/2 in. conduit connections.

The XFR010 is a 100 VA transformer without an enclosure. It can be used in any appropriate UL-listed enclosure and is used as a replacement transformer for the XFR100 or in EWC35/45 Series enclosures.

The XFR050 is a 50 VA transformer without an enclosure. It can be used in any appropriate UL-listed enclosure and is used as a replacement transformer for the EWC15/25 Series enclosures.

Features

•choice of 50 VA or 100 VA power rating

•color-coded wire leads for simple installation

•split-bobbin design for better noise immunity
