Thomas Research Products has issued a new expanded LED driver catalog for 2013. New products included this year are DC-input drivers. Featured are the company's reduced-size premium PLED series drivers. The extensive line of drivers listed in the catalog range from 12 through 300 watts. Constant-current, dimmable, and constant-voltage models are included. LED Drivers from TRP are optimized for quality, efficiency, longevity, and cost-competitiveness. All LED Drivers from TRP are UL 1310 or 8750 compliant, RoHS compliant, CE certified, and meet FCC requirements. All offer active power-factor correction and are protected from output over-voltage, over-current and short-circuit conditions. All models are either IP66 or IP67 rated, making them suitable for use in indoor and outdoor applications. Also featured are TRP's popular accessories for LED luminaires, including surge protectors, 480V step-down transformers plus recently introduced step-dimming modules.
