Full text manual (for reference)
Product bulletin for the Leviton OSP20-RDH / OSP20-RNH Super Duty Power Pack — the latest in the Leviton power pack family, combining transformer relay functions, occupancy sensor control, and manual/automatic operation into a single high-performance unit.
Overview
The OSP20-RDH/RNH uses Leviton's exclusive High Inrush Stability (H.I.S.™) circuitry, specifically designed to handle today's high inrush electronic ballast loads — including the latest T5HO and T4 ballasts — with unmatched durability and service life.
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
Key Features
- Extreme durability: exceeds WS-896 Federal Specification duty cycle requirements for specification-grade toggle switches
- Exclusive H.I.S. circuit designed to handle high inrush electronic ballast loads
- Zero-crossing design for reliability and extended life
- Mechanical latching relay — dependable 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: replaces traditional transformer relays and provides occupancy sensor control — ideal where code requirements/jurisdictions prohibit the use of 277V switch legs
- Manual-ON or Automatic-ON functionality for bi-level lighting control per CEC Title 24 requirements
- UL 2043 Plenum Rated
- 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
Wiring Diagrams
A bi-level switching diagram is also included in the full PDF, showing Zone 1 (Auto-ON) and Zone 2 (Manual-ON) wiring with color-coded low-voltage conductors, occupancy sensor connections, and local switch terminations.

Power Pack Capacity Formula
Leviton power packs can power one or more occupancy sensors. Since current consumption varies by sensor model, use this formula to determine the correct number of power packs and add-a-relays needed:
(# of Sensor Model A × Sensor A current consumption) + (# of Sensor Model B × Sensor B current consumption) + (# of Add-a-Relays × 50mA) < Power supply output per the ordering chart above.
| Sensor Model | Current Consumption |
|---|---|
| OSC04-I, OSC15-I | 10mA |
| OSWHB-I, OSWLR-I, OSWWV-I | 15mA |
| OSW12-M | 25mA |
| OSC20-M, OSC20-U | 30mA |
| OSC05-U, OSC05-M | 32mA |
| OSC10-U, OSC10-M | 40mA |
| OSA20-R Add-a-Relay | 50mA |
