Preliminary Data
MICROLV9
TM
Low Voltage LED Power Driver
Product Overview
The MicroLV
TM
range of LED Power Drivers is ideal
for driving Luxeon
TM
LEDs from a range of low
voltage power supplies.
The compact and efficient power electronics ensure
optimum operation of LEDs through a highly stable
constant current output.
The wide ranging input voltage enables one driver
solution to be used in a host of low voltage LED
lighting applications.
A unique power saving mode allows a reduced output
current to be selected with a simple switch. This
feature is useful in solar recharge and other battery
powered applications.
Typical Applications
Solar powered lighting
Architectural lighting
Marker & Orientation lights
Reading Lamps
Track Lighting
Display Cases
Signalling
Signage
Cycle, Caving and Flash Lights
