An LED fixture is only as good as its driver. Depend on Keystone’s 70+ year legacy of building world-class lighting power electronics for superior reliability and performance. Keystone offers a wide array of 0-10V dimmable LED drivers in a variety of form factors.We factory test 100% of every production run, so when you install a Keystone LED driver, you can count on it to perform. Keystone’s constant current LED drivers are ideal for general lighting applications in industrial, commercial, and residential environments where efficiency matters most. Constant current LED drivers maximize light output without over stressing the LEDs to provide consistent, even light. By controlling the maximum current going through the system, these LED drivers prevent thermal runaway. These drivers are required when the driver is used to power the LED load directly. With constant current drivers, the output current is fixed by the driver, while the output voltage varies depending on the LED load. The more LEDs the driver is powering, the greater the output voltage will be, up to a maximum as allowed by the driver specifications. |
