PAC2 Application Example

PAC2 Power Management

When power requirements exceed 50 watts, additional power supplies may be added. For example, each keypad

in the CNX-B series uses 3 watts; therefore, only 15 keypads (allowing for a margin of safety) can be connected

without adding an additional power supply.

To ensure sufﬁcient power to accommodate all the Cresnet devices (keypads, touch screens, shade/drapery

controllers, thermostats, sensors, and other interfaces) and to include voltage drops and wire runs, Crestron

recommends the CLX-PWS75 75 watt Cresnet power supply module, or the C2N-SPWS300 300 watt system power

supply.

The 75 watt power supply is designed to mount in a CAEN Automation Enclosure. A single CLX-PWS75 can be

installed in any single-width enclosure, or up to two may be installed side-by-side in a double-width enclosure.

Four Cresnet power ports are provided on the CLX-PWS75, which may be used to supply power directly to Cresnet

devices or to connect to the external power input ports of a PAC2 or PAC2M.

The 300 watt power supply, speciﬁcally designed for large Cresnet

control systems, operates with an input of 100 to 240 Vac, 4 amps

(maximum), and a noise rating less than 150 mV. The C2N-SPWS300

provides regulated 24 Vdc, 300 watt to Cresnet system components.

The C2N-SPWS300 is capable of delivering a nominal 75 watts of

power at 24 Vdc on any of its eight channels.
