Luminaires: Constant Voltage Drivers
• The LED light engine requires constant voltage instead
Copyright 2008 Lutron Electronics Co., Inc.All rights reserved. 11
• The LED light engine requires constant voltage instead
of constant current
• User needs flexibility in number of luminaires or length
of cove controlled by one power supply
• Typical Applications: accent, display, cove
