Leviton OPP20-0D0 20A Power Pack 24V Auto/Manual On

Product Overview

The Leviton OPP20-0D0 20A power pack provides line-voltage switching control for occupancy sensor-based lighting systems. Designed to interface low-voltage sensors with high-voltage lighting loads, it supports Auto-ON, Manual-ON, and local switch operation. This unit is used in commercial installations to manage lighting circuits while supplying 24VDC power to connected sensors.

Key Features & Design

• Functionality: 20A relay-based power pack that switches lighting loads while delivering 24VDC power to occupancy sensors.
• Installation context: Mounts inside or outside junction boxes or ballast cavities for flexible placement and retrofit opportunities.
• Notable specifications: Load Rating: 20A relay supporting lighting and general-purpose loads (fluorescent, LED, ballast, and resistive); Voltage Input: 120–230–277VAC, 50/60Hz; Control Modes: Auto-ON, Manual-ON, and local switch input capability; Power Output: 24VDC, 225mA for occupancy sensors; Relay Design: Mechanically held latching relay; Protection: Fail-safe return-to-closed (ON) circuitry; Inrush Handling: High Inrush Stability (H.I.S.) circuitry; Certifications: UL/cUL listed for energy management equipment.
• Contractor-relevant details: The mechanically held relay reduces standby energy use, and the fail-safe ON feature enhances safety during fault conditions, while the high inrush stability supports modern LED and ballast loads without nuisance tripping.

Performance / Benefits

This power pack enables reliable switching of high-voltage lighting loads while providing low-voltage power to occupancy sensors, simplifying system wiring in commercial applications. The mechanically held relay reduces standby power consumption, while fail-safe circuitry ensures lights default to ON for safety during faults. High inrush stability supports electronic ballasts and LED loads, helping prevent premature failures and improving overall system reliability.
