CU300AU

H-MoSS ® H-MOSS® Occupancy Sensors Hubbell Motion Sensing Switches Control Units - CU300AU Universal Control Unit H-MoSS ® Hu bbe ll M otion Sensing Switc he s The CU300AU Universal Control Unit automatically detects the line voltage input within the 120-277V range, eliminating the need for voltage specific control units. It contains an internal relay for the control of an external lighting load and is designed for use with low voltage 24V DC occupancy sensors. This control unit features Zero Arc Point Switching, which minimizes relay-contact wear from high inrush loads, and is capable of switching 20A loads. The CU300AU can power 1-4 sensors or 3 sensors and 1 AAR (Add-A-Relay) for multiple circuits. It is plenum rated and mounts inside or outside a junction box or inside a fluorescent fixture ballast cavity. Key Features • Universal Voltage- 120V-277V AC, 50/60Hz • Regulated 24V DC, 150mA Output Current Short Circuit Protected • Zero Arc Point Switching • Plenum Rated • Works with Complete Line of Hubbell H-MOSS® Ceiling and Wall Mount Sensors • UL and cUL Listed • 5 Year Limited Warranty Features and Benefits Features Benefits Universal Voltage- 120-277V AC One control unit for all your needs. Allows you to service multiple applications with one control unit. Automatic Voltage Detection Eliminates the need for specialized wiring, wiring is the same for all applications. The CU300AU automatically detects which voltage is being used. Zero Arc Point Switching Minimizes relay contact wear associated with high inrush loads. Plenum Rated Complies with requirements for use in a compartment handling conditioned air (plenum). Mounting Options Easily mounts inside or outside a junction box or inside a fluorescent fixture ballast cavity. www.hubbell-wiring.com H-MOSS® Occupancy Sensors Control Units - CU300AU Universal Control Unit Control Units Hubbell CU300AU provides a 24V DC power supply for 1 to 4 sensors or sensor/ Add-A-Relay combinations.
