System Power Supply:
C2N-SPWS300
Introduction
NOTE: If all eight channels
rovide the maximum rating
(75W), the unit would have to
supply 600 watts total. That
exceeds the C2N-SPWS300’s
300W capability. Therefore, a
channel can deliver up to 75W,
but every channel may not be
ully utilized. Some channels
may not be used at all.
Features and Functions
The C2N-SPWS300 is a 300-watt system power supply designed for large Cresnet
control systems (herein referred to as Cresnet system). It operates with an input of
100 to 240 VAC, 4A (maximum) and a noise rating less than 150mV.
The C2N-SPWS300 provides regulated 24 VDC, 300 W to Cresnet system
components. The C2N-SPWS300 is capable of delivering a nominal 75 watts of
power at 24 volts DC on any of its eight channels. Each channel is accessed at the
front panel of the unit via two black Cresnet type connectors per output. Outputs are
limited to 75 watts (3.125 amps typical) by an electronic circuit breaker. Each output
connector also has Cresnet Y-Z signals. All Cresnet signals are in parallel.
Functional Summary
• 24-volt, 300-watt Cresnet power supply
• Eight output channels (each with 75W rating) monitored and controlled by
a Cresnet port
• Power switch allows for single-point shutdown. Useful when unit is not
located at head end (refer to “Powering the Unit” on page 2 for details).
• Use Network Analyzer in SIMPL Windows to troubleshoot voltage levels.

System Power Supply Crestron C2N-SPWS300
Powering the Unit
NOTE: The C2N-SPWS300 is shipped with two power cable assemblies. One is
supplied for standard 120 VAC, 60 Hz as available in the United States. The other
has three un-terminated wires at one end and is supplied for international use or
installation within the Crestron CAEN.
Attach the correct cable assembly, connect it to AC power, and set the power switch
on the left side of the unit to either the PWR ON or PWR OFF SLAVE position.
Either position is capable of enabling the internal 300-watt power supply. Select one
position over the other based on the type of control required. For example, for a large
system with power supplies scattered throughout, it may be advantageous to
implement the PWR OFF SLAVE position so that a single switch at the head end can
execute a system-wide cold boot. Otherwise, one would have to turn off a switch at
each power supply in the PWR ON position.
PWR ON Position
In the PWR ON position, the C2N-SPWS300 acts as a stand-alone system. All of the
green LEDs illuminate successively as power is applied to each channel (1 through
8) until all eight channels are powered up.
NOTE: Successive start up minimizes load current inrush current strain on the
internal 300-watt supply.
If the green LEDs do not illuminate, press and release the system RESET button.
PWR OFF SLAVE Position
In the PWR OFF SLAVE position, 24 VDC must be applied across the outer two
pins (24 and G) of the NET connector located in the upper right corner to enable the
internal supply. Once enabled, the green LEDs illuminate successively as power is
applied to each channel (1 through 8) until all eight channels are powered up.
When the power switch is in this position, 24 VDC from the Cresnet network is used
to activate a relay, which in turn switches on the internal 24 VDC supply. If Cresnet
power is removed, the C2N-SPWS300 turns off.
Channel Details
Each channel contains an electronic circuit breaker that detects over current faults for
that channel. The electronic breakers are activated if the output power exceeds 75
watts nominally, but are guaranteed to always trip before output power reaches 100
watts. Each channel has 4-amp fuses to provide an additional means of limiting
current. The fuses are not accessible to the user.
When an over current fault has occurred on a channel, the red overload LED
(OVRLD) on the front panel illuminates. The micro-controller attempts to
automatically turn on each faulted channel twice before shutting off the channel and
illuminating the red LED. At this point only pressing the RESET button associated
with each channel allows the microcontroller to turn off the red OVRLD LED and to
attempt to turn on the channel. In the event that the over current fault has been
removed the channel powers up. If an overload is still present, the micro-controller
attempts to turn on the channel an additional two times before the red LED
illuminates again. Firmware continuously monitors all channels and all channel over
current faults are reported to Cresnet.

Crestron C2N-SPWS300 System Power Supply
Pressing a RESET button during normal operations shuts off a channel for as long as
the button is held down. If the button is released, the channel turns on.
System Details
In the event that the full 300 watts (12.5 amps) of the supply is exceeded, all eight
channels turn off simultaneously, the eight red channel overload LEDs (OVRLD)
illuminate, and the red system overload LED (OVRLD) illuminates. Pressing the
system RESET button causes the unit to reset each channel individually until all
channels are active (assuming the overload has been removed). Pressing the system
RESET button during normal operations causes the unit to shut down all channels
and turn them back on when the button is released.

System Power Supply Crestron C2N-SPWS300
Physical Description
The C2N-SPWS300, shown after this paragraph, is housed in a sturdy 1/8-inch black
anodized aluminum enclosure. A power selection switch and pigtail input power
cable with an IEC320 socket are located to the left side of the unit. A screened
overlay covers the front panel. The front panel has 17 four-pin network connectors.
The data lines (Y and Z pins) on all network connectors are internally wired in
parallel. One network connector in the upper right corner of the front panel must
connect to a Crestron
SLAVE position. Power and network LEDs support this connector. The other 16
network connectors are divided into eight pairs. Each pair is a channel used for
integration of the unit into the Cresnet system. Each of the eight channels also has an
overload and power LED as well as a reset button. In the lower right corner of the
front panel there is an overload LED and reset button for the system. A recessed
setup switch and LED are located above the system LED and button.
This power supply has been designed to mount horizontally on its back in a rack
cabinet or on a wall. At the shorter sides of the unit, the enclosure extends at a right
angle to provide mounting flanges equipped with screw holes (hardware supplied by
others).

Ports
With the exception of the IEC320 connector on a pigtail cord (for application of AC
power), all connections to the C2N-SPWS300 are made via the ports on the front
panel.
The single four-pin network connector in the upper right corner on the front panel is
used to accept 24 VDC when the power switch is set to the PWR OFF SLAVE
position. Data provided to this connector is made available to all other network
connectors since the data signals are in parallel. Refer to “Network Wiring” on page
7.
The eight pairs of four-pin network connectors centrally located on the front panel
are provided for distribution of power and data signals. Data and ground pins are
internally wired in parallel from channel to channel. Each pair or channel is capable
of delivering a nominal 75 watts of power at 24 VDC.
Indicators
A green LED (PWR) in the upper right corner of the front panel illuminates when the
internal 300-watt power supply is enabled. Refer to “Powering the Unit” on page 2
for details. The yellow LED (NET) located below the PWR LED illuminates when
the program running in the Crestron control system polls the unit.

Each power supply channel (1 through 8) has a green LED (PWR), which
illuminates when 24V is present at that output. A red LED (OVLD) for each channel
illuminates when there has been a short circuit or the load exceeds the nominal 75
watts for any channel.
A system-wide red LED (OVLD) illuminates when the full 300 watts (12.5 amps) of
the C2N-SPWS300 is exceeded.
Pushbuttons
A pushbutton (RESET) associated with each channel allows the user to reset the
circuit breaker for each channel and turn on that channel. Power is restored to an
overloaded channel if the excess load has been removed from the channel or the
channel was set into overload because of a system overload caused by another
channel.
A system-wide pushbutton (RESET) is available to reset all eight-channel circuit
breakers and turn on all channels assuming excessive loads have been removed.

SETUP LED and Pushbutton
The C2N-SPWS300 is TSID ready. The SETUP pushbutton and its associated LED
located on the front panel are used for setup of the unit’s network ID during the
initial configuration of a Cresnet system or when the device is being added/replaced.
Refer to “Method B (Touch Settable IDs)” on page 9 for detailed information.
Industry Compliance
As of the date of manufacture, the C2N-SPWS300 has been tested and found to
comply with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling (N11785)
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Setup
System Requirements
A C2N-SPWS300 is necessary to supply power to modular "card cage" control
systems (i.e., CNRACKX, CNRACKX-DP, and RACK2), since these units do not
employ internal power supplies. C2N-SPWS300s may also be required in a Cresnet
system managed by an integrated control system (i.e., AV2 or PRO2) if the power
requirements of the system components are greater than the internal 50-watt power
supply of the control system.
To determine the number of C2N-SPWS300s necessary to power all Cresnet
components in a particular Cresnet system, the total system power requirement must
be calculated. This is accomplished by adding the power requirements of all system
components. Refer to the leading specifications of each component for individual
power requirements. The total system power requirements should include the control
system, all cards in the control system, any expansion racks and associated cards,
and any network units. Once the total system power requirement is calculated, the
number of C2N-SPWS300s used should be selected such that their combined output
wattage meets or exceeds the total system power requirement.
Another important system factor to consider is the fact that a single network unit
cannot be powered by two different C2N-SPWS300s. In other words, one C2NSPWS300, which is not being used to its full capacity, cannot contribute its unused
power to 'help' another C2N-SPWS300 power the network units connected to it. For
example, suppose a system consists of a RACK2 (cards included) with a power
requirement of 20 watts, a CNX-DVP4 (50 watts required), five Crestron Isys™
touchpanels (each with a power requirement of 46 watts; including cards), and other
ancillary Cresnet devices with a combined power requirement total of 25 watts. The
total system power requirement is 325 watts. The first C2N-SPWS300 could power
everything, but the CNX-DVP4 on seven channels for a total of 275 watts. A second
power supply (C2N-SPWS3000 or CNPWS-75) could power the CNX-DVP4 for a
total of 50 watts.
