Crestron Lighting Control System
The PAC2 processor provides 50W of power for keypads and touchpanels. Each
keypad in the CNX-B series uses 3-watts, therefore only 15 keypads can be
connected without adding another power supply. Make sure there is sufficient power
in the system design to accommodate all the keypads, touchpanels, voltage drops,
and wire runs. Additional power supplies should not be mounted on CAEN-UMP
plates in an enclosure that contains dimmer units because this introduces low-voltage
in the high-voltage section of the enclosure. If required, an extra power supply,
attached to a CAEN-UMP plate, can be added to a separate CAEN enclosure.
Crestron recommends the C2N-SPWS300 Power Supply; a 300-watt system power
supply designed for large Cresnet control systems. 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.
The PAC2 connects all the user interfaces:
•
Keypads and wall switches
•
touchpanels
•
contact closures
•
emergency switches
•
override switches
•
backup Cresnet controller input
•
output relays
•
fault indicator
•
computer data port
The PAC2 enables the customer to efficiently control not only the lighting in their
home, but also other systems such as HVAC and security.
