SensorWorx SWX-900 Power Pack 16A 120–277V

Product Overview

The SensorWorx SWX-900 is a line-voltage power pack controller designed to power low-voltage occupancy sensors and switch connected lighting loads in commercial lighting control systems. Operating on 120/277VAC, the SWX-900 converts incoming line voltage to Class 2 low-voltage power while providing relay-based switching for occupancy-based and automated lighting control application

Key Features & Design

• Functionality: Line-voltage power pack controller that powers low-voltage sensors and switches connected lighting loads through an integrated relay.
• Installation context: Designed for commercial lighting control applications requiring occupancy sensor integration, automated switching, manual-on functionality, or multi-zone lighting control.
• Notable specifications: 120/277VAC operation; Class 2 18VDC output; 20A general-purpose load rating; 16A electronic ballast and LED driver rating; zero-cross relay switching; plenum rated (UL 2043); integrated test/programming button; 1/2-inch knockout mounting; blue housing.
• Contractor-relevant details: Microprocessor-controlled switching helps extend relay life when controlling high-inrush LED and ballast loads, while optional auxiliary switch input configurations support manual-on, hold-on, hold-off, and partial-on and partial-off lighting strategies

Performance / Benefits

In commercial lighting control applications, the SWX-900 provides reliable switching performance for occupancy sensors and automated lighting systems. Zero-cross switching technology helps reduce relay wear and improve long-term reliability, while integrated low-voltage sensor power simplifies installation and supports scalable sensor-based lighting control configurations across offices, classrooms, retail spaces, and other commercial environments.
