U.L.® Listed Power Transformers for Heavy-Duty AC Power Requirements

Alpha Communications® model SS102A, SS104 and SS106 Class 1 (primary)/Class 2 (secondary) transformers offer compact, easy to install low voltage AC power sources for use with various Alpha Communications® intercom systems.

All three (3) models are U.L.® listed and will safely take themselves off-line when overheated. The transformers are constructed for easy installation in a standard 1/2" knockout, or for surface mount installations, and may be used in plastic or metal boxes.

Primary wire connections are made using the pre-stripped pigtails and ground wire; secondary connections are made using screw terminals. All models are for indoor use only.
