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.

: 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
