PRODUCT DATA
OSP/OSA Power Pack Series
FEATURES
OSP20-ND0
• Self-contained transformer and relay
• Internal voltage regulator – regulated 24VDC
current, 150mA output
• Fast installation - mounts inside or outside of
a junction box, or inside a fluorescent ballast
cavity with a simple twist-on nut
• Single or multiple luminaire control
• Zero-crossing circuitry
• UL 2043 Plenum Rated
• Companion Add-A-Relay provides additional
capacity (OSA20-R00)
• NAFTA compliant
OSP20-RD0/OSP15-R30
Includes the same features as the OSP20-ND0,
plus:
• Dry contact relay for combined sensor control
of lighting and heating/air conditioning
• Dry contact for designing controlled closure
• Form A relay for interface to BAS/BMS
OSP20-RDH
Includes the same features as the OSP20-RD0,
plus:
• Auto-ON and manual-ON inputs for occupancy
sensors
• Hold-ON input — when activated, unit is always
ON regardless of any other input
• Hold-OFF input — when activated, unit is always
OFF regardless of any other input
• Local inputs for momentary or maintained dry
contact low voltage switching
• Robust mechanical batching relay designed to
perform as a Form C normally closed device
• Increased power supply output to 255mA
• Upon loss of power, latching relay maintains
current state (closed or open)
• H.I.S. >(High In-rush Stability)
• Heavy-duty zero-crossing circuitry
• Robust mechanical latching relay
OSA20-R00
•15A relay can be added to any OSP20 power
pack for flexible design
• Provides cost-conscious design flexibility
• Inexpensive solution for mixed voltage lighting
design
• Used for expanding circuit switching capacity
• Use OSP20 power packs for emergency lighting
circuits and OSA20 Add-A-Relays for
inexpensive control of normal lighting
