Constant Current Demonstration Board suits LED applications.
June 19, 2008 -
Providing regulated current as required for direct-drive multi-LED applications, Model P048F048T24AL-CC can be used to deliver adjustable current up to 240 W (5 A at 48 V) when employed as standalone non-isolated source, or can be combined with VTM(TM) transformers to provide adjustable isolated current up to 100 A. Device offers current accuracy of 99.7% across load range. It includes fused PRM inputs, provision for mounting heat sink, and system enable and disable.
V.I Chip, Inc. Announces New LED Constant Current Demonstration Board
Andover, MA, May 27, 2008...V.I Chip, Inc., a subsidiary of Vicor Corporation (NASDAQ: VICR), has announced a constant current (CC) PRM(TM) regulator demonstration board for light emitting diode (LED) applications such as street & stadium lighting, high-end projectors, active outdoor advertising and architectural installations.
The board provides a precisely regulated current as required for direct-drive multi-LED applications where the intensity and brightness are controlled by regulating the current through the LEDs. The board can be used to provide adjustable current up to 240 W (5 A at 48 V) when employed as a standalone non-isolated source or can be combined with the range of VTM(TM) transformers to provide an adjustable isolated current up to 100 A.
"In terms of efficiency, a PRM+VTM pair uses less than 1 W for every 1,000 Lumens generated by the LEDs for high performance applications," said Stephen Oliver, Vice President of Marketing and Sales. "This is a perfect complement to using the BCM(TM) bus converters with low voltage driver ICs for lower power applications such as LED TV backlighting."
The CC board demonstrates the high power density of the PRM with current accuracy of 99.7% across the load range. The board has Kelvin connections for measuring the efficiency of the V.I Chip(TM) components independent of load connect losses. Oscilloscope probe jacks are available for measuring output voltage, including output voltage ripple. The board has fused PRM inputs, provision for mounting an optional V.I Chip pushpin heat sink, and system enable and disable.
The LED demonstration board (P048F048T24AL-CC) is priced at $125 and is available from stock. To order, contact Vicor Customer Service at 800-735-6200 or e-mail custserv@vicr.com.
