This product has been discontinued. Please contact Crestron True Blue Support at 1-888-CRESTRON for a replacement solution or more information.
- 300 Watt regulated power supply
- 8 independently managed outputs
- 16 Cresnet distribution ports
The C2N‑SPWS300 provides a convenient and compact centralized power and termination solution to support the myriad touch screens, keypads, and other peripherals that make up a Crestron® system.
Intelligent Power Distribution
The C2N‑SPWS300 is a 300 Watt regulated power supply designed for powering a large network of Cresnet® devices. Power is supplied through 8 individually managed outputs. Each output is rated for up to a maximum of 75 Watts, with a total system rating of 300 Watts. Electronic circuit breaker protection is provided on every output, which can be individually monitored and reset from the control system. The voltage level at each output can even be monitored along with the ambient temperature and fault status for the complete power supply system.
Sequential Switching
To minimize current inrush upon startup, the C2N‑SPWS300 implements sequential switching of its 8 outputs. The startup process may be activated automatically when AC power is applied, or when 24 VDC is sensed coming from the control system or another power supply.
Cresnet Distribution
Connected to the Cresnet port of any Crestron control system, the C2N‑SPWS300 provides a total Cresnet distribution solution. Carrying both data and power, the 16 Cresnet ports afford great flexibility for the termination of numerous Cresnet devices, with easy expansion using C2N‑HBLOCK termination blocks (sold separately). It is also ideally designed to enhance the built‑in Cresnet distribution capabilities of the Crestron control system.
Versatile Mounting Options
The C2N‑SPWS300 can be installed in a Crestron CAEN Automation Enclosure using the optional CAEN‑MK (sold separately), or it can be rack mounted using the optional C2N‑RMAK (sold separately). Alternately, the C2N‑SPWS300 can be placed on a shelf or mounted on any vertical surface using its built‑in mounting flanges.
