Acuity Sensor Switch SP20 Power Pack contactor
Relay pack powers up to seven low-voltage occupancy sensors with a 20 A relay, accepting 120, 240 or 277 V AC input and delivering 15 V DC output while meeting UL2043 plenum.
- Powers up to seven sensors from a single pack
- Handles 120, 240 and 277 V AC inputs with 15 V DC output
- Delivers 20 A relay switching for reliable load control
- Meets Plenum UL2043, RoHS and Title 24 compliance standards
- Operates from 14 to 122 °F in a compact 3 × 2.25 × 1.88 in enclosure
Relay Pack for Low-Voltage Sensors
The Acuity Sensor Switch SP20 Power Pack is a relay module designed to work with Series Acuity low-voltage occupancy sensors. It provides a 20 A switching capacity for lighting or other loads. The unit operates on 120, 240, or 277 V AC input and delivers 15 V DC output to power connected sensors. It is plenum rated per UL2043 and meets Title 24 and RoHS requirements.
Hard-Wired Integration for Building Systems
The pack communicates with sensors through hard-wired connections and fits inside standard enclosures measuring 3 in high, 2.25 in wide, and 1.88 in deep. A single unit supports up to seven sensors, reducing the number of power packs required in a zone. The integrated 20 A relay switches line-voltage loads directly, freeing the low-voltage sensor network from carrying high current. Operating range spans 14 to 122 °F for indoor commercial environments.
Suited for Commercial Lighting Control Projects
This power pack suits contractors and facility managers adding occupancy-based control to new or retrofit installations where plenum-rated, hard-wired sensors are specified. It is not intended for wireless sensor protocols, line-voltage sensor inputs, or applications requiring more than seven sensors per pack. Buyers needing higher relay counts, different input voltages, or wireless communication should look at alternative control architectures.
