Leviton OSP Power Pack

Combines transformer relay functions, occupancy sensor control, and manual/automatic operation into a single high-performance unit.

The Power Pack contains a power supply, a load switching relay and an HVAC relay. The power supply provides Class II low-voltage power for OSCxx, OSWxx, ODCxx, and ODWxx Series Occupancy Sensors. The OSP Power Packs can also supply power to the OSA20, Add-A-Relay. The relay in the Power Pack is controlled by the occupancy sensors connected via the 22 Gauge Blue "occupancy" wire. Multiple occupancy sensors can be connected to a single Power Pack in order to fully cover an area. The Power Packs include zero cross switching circuitry to minimize inrush current associated with incandescent and electronic ballasts. This reduces wear and tear on the relay contacts making the Power Pack last longer.

The OSP20-RDH is in the Leviton Power Pack family, providing a wide array of switching solutions into a single unit. Exclusive Leviton High Inrush Stability (H.I.S.) circuitry is specifically designed to handle today's high inrush electronic ballast loads and offer unmatched durability and service.

• For use with OSCxx, OSWxx, ODCxx, and ODWxx Occupancy Sensors
• Title 24 Compliant
• Hold On/ Hold Off capabilities
• Regulated 24VDC, 150mA output current
• Mounts inside Fluorescent Ballast cavity
• Mounts inside or outside Junction Box
• Rated for Plenum spaces

The AutoOn/Override Power Pack can be turned ON and OFF automatically using an occupancy sensor input, a timer, panel or BAS input, and manually from an optional low voltage momentary switch.

APPLICATIONS

Use a Leviton Power Pack with Leviton Occupancy Sensors in the following applications:

• Bi-level lighting applications
• Classrooms
• Conference Rooms
• Offices
• Load Shed/Interface Hold OFF Applications
• Retail Hold ON/Bypass Applications
• Anywhere optimal lighting and energy savings are desired

FEATURES

• Extreme durability: exceeds WS-896 Federal Specification duty cycle requirements for specification grade toggle switches.
• Exclusive H.I.S. (High Inrush Stability) circuit designed to handle high inrush electronic ballast loads, including T5HO and T4 ballasts.
• Zero crossing design for reliability and extended life.
• Mechanical latching relay for dependability and robust for all load types.
• Return-to-on design provides fail safe operation in the event of power loss or malfunction.
• Transformer Relay Function: OSP20-RDH/RNH replaces traditional transformer relays and provides occupancy sensors control. Ideal for use where code requirements/jurisdictions prohibit the use of 277V switch legs.
• Manual-ON or Automatic-ON functionality for use in bi-level lighting control per CEC Title 24 requirements.
• UL 2043 Plenum Rated.
• CUL/US, FCC and NOM certified.
• Meets ASHRAE Standard 90.1 requirements.
• Endurance tested to over 1,000,000 cycles at full load.
• Integrates with low voltage momentary and maintained switches to control occupancy sensors.
• Conduit adaptor included for low voltage connections.

Leviton's OSP Series Power Packs are UL 2043 plenum-rated. The polycarbonate housing is UL 94HB rated, evaluated to the 5" flammability requirement, with Teflon-coated low-voltage leads. This plenum rating provides options to install the Power Pack in a junction box, fluorescent ballast cavity, or air handling space above the ceiling commonly referred to as a "Return Air Plenum".

The plenum rating ensures that Power Pack materials have passed rigorous burn testing standards and are suitable for installation in plenum spaces used to transport environmental air. The plenum space above a suspended ceiling or below a raised floor is typically used as the air return for a building's HVAC system. A fire in a plenum may go undetected and produce toxic fumes that can be dispersed throughout the entire building by the HVAC system. As a result, fumes anywhere in the building could endanger occupants. Installing products with plenum-rated materials that burn at a much higher temperature and emit fewer fumes can minimize this risk.
