The RTS PS-15 is a dedicated power supply unit designed to provide stable, low-voltage DC power to RTS (now part of Bosch Communications Systems) wired party-line intercom systems and related peripherals. This unit serves as the central power hub for an intercom network, converting standard AC mains voltage (typically 100-240V) to the regulated DC voltage required by the system's main stations, key panels, and beltpacks. Its primary function is to ensure reliable and consistent operation of all connected intercom components, which is critical for clear, uninterrupted communication in broadcast, live production, and theatrical environments. The PS-15 is engineered for 24/7 reliability, with robust construction and protection against over-current and short-circuit conditions.

A key feature of the PS-15 is its ability to power multiple intercom lines and devices from a single unit. It typically provides multiple output channels or a single high-current output that is distributed through the system's cabling. The power supply often includes status indicators, such as LED lights for power and fault conditions, allowing for quick visual diagnostics. It is designed for rack-mount installation, integrating neatly into technical equipment racks alongside the intercom mainframes and other production gear. The unit's output is precisely matched to the voltage and current specifications of RTS intercom equipment, ensuring optimal performance and preventing damage to sensitive audio circuits.

Installation is straightforward for qualified technicians, involving connecting the AC input and routing the DC output to the intercom system's distribution points. The RTS PS-15 Power Supply exemplifies a critical, yet often overlooked, component in professional intercom infrastructure. By providing clean, regulated power, it forms the foundation for a stable and dependable communication network, enabling production teams to coordinate effectively under the demanding conditions of live events and broadcasts.
