Alpha SS105B Intercom Plug-in Power Transformer, 16VAC, 20VA, U.L. Listed Class II, White Plastic Housing

Deliver dependable power to your entry, intercom and security devices with the Alpha Communications SS105B Intercom Plug-in Power Transformer. Built for installers and facilities managers who need a compact, attractive power solution, this plug-in transformer supplies a steady 16VAC at 20VA to drive door stations, intercom panels and small surveillance accessories. The SS105B installs quickly where pigtail-type transformers are impractical or unsightly, making it ideal for visible residential and office deployments.

Safety and code compliance are built in: the unit is UL-listed as a Class II indoor transformer and includes an internal thermal fuse to protect against overheating. That means fewer callbacks and easier integration into security, monitoring and access control projects. The clean white housing keeps installations neat in lobbies, reception areas and equipment closets, while the reliable output reduces voice/failures and power-related troubleshooting.
