Crestron control systems can put a friendly face on any complete integrated AV or
automation solution. To support the myriad touchpanels, keypads, and other
peripherals that make up a control system, the C2N-SPWS300 provides a
convenient and compact centralized power and termination solution.
Cresnet®—Cresnet is the communications backbone for Crestron touchpanels,
keypads, lighting dimmers, and more. The Cresnet bus is a simple, yet flexible
4-wire network that provides bidirectional communication and 24 Volt DC power
for up to 252 Cresnet devices. With cable lengths up to 5000 feet, the Cresnet
wiring topology allows almost limitless wiring configurations.
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 on eight individually managed outputs. Each output is rated for up to 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 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 eight outputs. The startup
process may be activated automatically when AC power is applied, or when 24
Volts DC is sensed coming from the control system or another power supply.
Cresnet Distribution—Connected to the Master port of any 2-Series 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. It is also ideally designed to enhance the built-in Cresnet
distribution capabilities of the PAC2 Professional Automation 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
rack mounted using the optional C2N-RMAK (sold separately). Alternately, the
C2N-SPWS300 may simply be placed on a shelf or mounted to any vertical surface
using its built-in mounting flanges.

SPECIFICATIONS
Load Ratings
Per Channel: 75 Watts (3.125 Amps) @ 24 Volts DC regulated
System Total: 300 Watts (12.5 Amps) @ 24 Volts DC regulated
Ripple / Noise: <150 mV
Load Protection: Electronic circuit breaker per channel, each rated at 75 watts nominal / 100
watts maximum; 4 Amp, 125V internal fuse; all channels shut off in case of total system
overload
Sequential Startup: Outputs activate sequentially when power supply system is enabled (see
PWR ON, PWR OFF/SLAVE control)
Power Requirements
4 Amps, 100-240 Volts AC, 50/60 Hz
Connections
1 – 8: (16) 4-pin 5mm detachable terminal blocks comprising (2) paralleled Cresnet ports
per each of (8) output channels;
24 Volt DC power outputs with Cresnet data pass-thru from NET port
NET: (1) 4-pin 5mm detachable terminal block
Ordinarily connects to the Master Cresnet port of a control system
Cresnet data ‘Y’ and ‘Z’ terminals pass through to ports 1 – 8
Applying 24V DC to the ‘24’ and ‘G’ terminals enables the power supply system when in
“SLAVE” mode
Power: (1) attached input power cable (~1 ft long) with inline IEC320 socket
Connects to grounded AC power source using 3-prong power cable or pigtail cable, both
provided
Controls
PWR ON, PWR OFF/SLAVE: (1) rocker switch; enables/disables the power supply system
if no external DC voltage is applied to the NET port, or selects “SLAVE” mode to allow
enabling the power supply system remotely by applying an external 24V DC signal to the
NET port
RESET 1 – 8: (8) miniature pushbuttons; each resets its respective output channel, or
momentarily disables the channel while held
SYSTEM RESET: (1) miniature pushbutton; resets all output channels sequentially, or
momentarily disables all channels while held
SETUP: (1) miniature pushbutton; used for touch-settable ID (TSID)
LED Indicators
PWR 1 – 8: (green) Indicate 24V DC power present at each channel output
OVRLD 1 – 8: (red) Indicate a load in excess of 75 watts on a given channel, channel
output disabled
SYSTEM OVRLD: (red) Indicates a total load in excess of 300 watts on the power supply
system, all channels disabled
PWR: (green) Indicates power supply system is enabled
NET: (yellow) Indicates communication with Cresnet system
SETUP: (red) Used for touch-settable ID (TSID)
Environmental
Temperature: 41° to 104°F (5° to 40°C)
Humidity: 10% to 90% RH (non-condensing)
Enclosure
Black anodized aluminum, surface mount box with (2) integral mounting flanges
Rack Mount: 3U 19” rack-mountable using C2N-RMAK (sold separately)
CAEN Automation Enclosure: Occupies 1 module space in a single-width enclosure, or
2 side-by-side module spaces in a double-width enclosure; requires CAEN-MK (sold
separately)
