The Dynasound’s DSSDT-12 step down transformer and junction box assembly is designed to provide localized power to 12-Volt equipment networks. When used in conjunction with Dynasound’s DS1082 self-contained sound masker, the complete DSSDT assembly can provide adequate power for network of up to twenty sound maskers. The DSSDT accepts standard 110VAC and steps down the voltage to operate 12-Volt devices, meeting all Class Two requirements. The DSSDT features an internal breaker that will protect the valuable speaker array from destructive power surges. The transformer is available by itself (model number DSSDT12), for attachment to an existing electrical box or as a complete transformer/junction box assembly (model number DSSDT12A).
