Application
The LBU10-P is a universal input (120-277V) emergency LED battery pack that
works with an AC LED driver to allow an LED lighting load to be used in both
normal and emergency operation. When normal AC power is lost, the LBU10-P
operates to provide 10 watts of constant emergency power at a rated output
voltage of 20-56Vdc. The constant power design provides backup for a minimum of
90 minutes with no loss of emergency lumen output. When used with emergency-
only LED fixtures, no AC driver is needed. The UL924 Listing allows for both field
and factory installations of suitable LED loads including LED luminaires, DC voltage
driven LED replacements for fluorescent lamps and others.

Description
Remote Test Switch/Indicator
PLRTS is an optional test switch that includes a wall
plate for a single gang J-box. Only one LBU10-P series
emergency driver can be wired to each PLRTS switch at a
time. Remote switch is intended to be used in place of the
internal switch supplied with the driver. Use Class 2 wiring
methods for installing switch and wiring. Switch wire
length can be 50ft maximum from the emergency driver.

Illumination
The LBU10-P will operate an LED load, that has a power rating of 10 watts or greater, for a minimum of 90 minutes. Using the LED
load’s efficacy in lm/w, as published by the Design Lights Consortium website (http://www.designlights.org), EnergyStar - Certified Products -
product finder website (http://www. energystar.gov/productfinder) or given by the luminaire manufacturer on product catalog specification
sheets, lumen output can be calculated by multiplying by the LBU10-P output power (10w).
Specifications
Operation
The LBU10-P emergency LED Driver and battery pack is designed to provide a minimum of 90 minutes of emergency lighting to commercial or
industrial LED fixtures. Operation is fully automatic. A solid-state charger maintains the battery at full charge as long as utility power is present.
Upon interruption of utility power, the unit will activate and the automatic transfer circuit will switch to the emergency mode, keeping the LED
load illuminated for a minimum of 90 minutes. Lumen output during emergency mode is estimated as described below. Upon restoration of util-
ity power, the LBU10-P emergency battery pack will return to the charging mode. Full battery recharge is accomplished within 24 hours. A test
switch and LED status indicator light is provided for testing and monitoring of unit performance.
You can estimate the egress lighting illumination levels by doing the following:
A) Find the efficacy of the LED load, which will be found in the Design Lights Consortium database. This number will be given in lumens
per watt (lm/w).
B) Lumens can be calculated by multiplying the output power of the emergency LED driver (10W) by the efficacy of the LED load. In
many cases the actual lumen output in emergency mode will be greater than this calculation yields, however it will provide a good
estimate for beginning the lighting design of the system.
Lumens In Emergency Mode = Lumens Per Watt of Fixture * Output Power of Chosen Product
(LUMENS) = (LM/W) * W
C) Using the results of this calculation and industry standard lighting design tools, calculate the anticipated illumination levels in the
path of egress.
NOTE: After installation, it will be necessary to measure the egress lighting illumination levels to ensure compliance
with national, state and local code requirements.
Installation
The LBU10-P Emergency LED Driver and battery pack does not affect normal LED fixture operation and may be used with either switched or
unswitched fixtures. If a switched fixture is used, an unswitched hot lead must be connected to the emergency ballast. The emergency battery
packs must be fed from the same branch circuit as the AC LED driver. Due to its thermoplastic construction, the LBU10-P must either be installed
inside the fixture, or enclosed if remote mounted outside the fixture. The LBU10-P emergency battery pack is suitable for use in damp locations
where the ambient temperature is between 0°C (32°F) and 55°C (131°F). It is not suitable for installation in heated air outlet fixtures and wet or
hazardous location fixtures.
