The Clear-Com PS-452 is a professional-grade intercom power supply that provides stable, regulated DC power to drive extensive two-channel intercom systems. Housed in a durable 1U rackmount chassis, it is engineered for demanding broadcast, theatrical, and production environments. Each of its two channels can power multiple user stations and beltpacks via standard 3-pin XLR connectors, which carry both the DC power and the audio signals. The PS-452 features built-in protection against short circuits and automatically resets once a fault is cleared, ensuring system reliability. Front-panel controls and status indicators allow operators to monitor system health, enable/disable channels, and detect faults instantly.
