Hubbell Lighting Components
ELGIN, Ill., Dec. 11, 2014 — 
Offering OEMs a flexible, easy way to reduce complex parts inventory, the LED39WPR series of constant-current LED drivers from Thomas Research Products does not require a computer workstation or software tools.
Output current is selectable from 190 to 700 mA by simply plugging in the appropriate resister. Configuration can be done on the production line.
The drivers are designed for use in downlight luminaires and include 0- to 10-V dimming. They also offer flicker-free output with high power factor and low total harmonic distortion (THD).
