Talkaphone PCS-SD-277-350 PCS-SD Series 350VA Step-Down Transformer, 308/277/208VAC to 120VAC

Keep critical security and surveillance systems powered and dependable with the Talkaphone PCS-SD Series Step-Down Transformer (model PCS-SD-277-350). Designed for integrators and facilities managers, this 350VA transformer converts higher building voltages — 308VAC, 277VAC, or 208VAC — down to a reliable 120VAC output so intercoms, access control modules, and monitoring devices receive consistent power. The wide input range and 350VA capacity minimize the need for multiple transformer models on mixed-voltage sites, simplifying inventory and installation.

Built for continuous operation in security, emergency communications, and surveillance installations, the PCS-SD step-down transformer helps reduce downtime and supports clean, stable power for sensitive electronics. Its compact footprint fits neatly in equipment closets and service panels, making it easy to integrate into new builds or retrofit projects. Specify the Talkaphone PCS-SD-277-350 when you need a dependable, space-saving power solution for cameras, control panels, and audio/video monitoring equipment. Contact our team or add to your project BOM to ensure consistent 120VAC power for your next security deployment.
