The Crestron CNPWS-75 is a 250V networked power supply designed to deliver reliable, centralized power to Cresnet devices within a Crestron control system. Cresnet is Crestron's proprietary control network that carries both power and data over a single cable, simplifying wiring for devices like keypads, sensors, and interface panels. This power supply serves as the central power hub, converting mains AC voltage (100-240VAC) to a regulated 24VDC output specifically for the Cresnet bus. Its 75-watt output capacity allows it to power a significant number of Cresnet devices from a single location, reducing the need for multiple, scattered wall transformers and contributing to a cleaner, more organized installation within equipment racks or electrical closets.

The unit is engineered for integration and reliability in commercial and residential automation systems. It features network connectivity, allowing it to be monitored and controlled via the same Cresnet bus it powers. This enables system diagnostics, such as remote power cycling of connected devices, and integration into the overall system management. The power supply is built with protection features including over-current, short-circuit, and over-temperature safeguards to ensure the safety and longevity of both the supply itself and the connected Cresnet devices. Its compact, rack-mountable design makes it suitable for professional installations where space and neatness are priorities.

By providing a robust, managed, and centralized power source for the Cresnet network, the CNPWS-75 forms a critical infrastructure component in a Crestron system. It ensures stable operation of all connected low-voltage control devices, contributing to the overall reliability and performance of the automation system. This is essential for maintaining uninterrupted control of lighting, AV, climate, and shading in demanding 24/7 environments.
