As you probably already know, in Canada we face a unique challenge with 347V branch circuits.
As a relatively small marketplace, driver manufacturers across the globe are reluctant to spend the time, energy, and associated costs to develop 347V drivers. As such, whenever possible, CSC LED incorporates proven, reliable, high voltage drivers to accommodate our customer’s need for 347V applications. In many of our fixtures, virtually identical DLC accepted drivers are used for high/low voltage inputs. DLC does not distinguish between or require separate listings for the two voltage inputs. All performance parameters remain the same.
That being said, in many cases, a step-down transformer is a more practical and/or cost effective solution. We are often asked if the step-down transformer will affect the DLC listing in any way. The answer is no, it does not. DLC focuses on the overall performance of the luminaire including: driver reliability, LED light engine, overall fixture efficacy, colour shifting, etc. The addition of a step-down transformer does not affect any of these performance features. DLC does not currently list voltage inputs in their listings. In some cases, CSC LED may have dual DLC listings for the same product with low and high voltage drivers. This is a voluntary step we have taken to try and make our customers search and rebate application processes as seamless as possible.
STEP-DOWN TRANSFORMER / DLC EXAMPLE:
CSC LED panel lights have a 120-277V universal driver input. For 347V applications, we supply a simple knockout mount lighting transformer (347V- 240V) which takes seconds to install in the field. This transformer is cUL listed for this very purpose and does NOT affect the fixture’s DLC listing.
