Many LED & conventional lighting products are designed to derive power from standard 120V or 240V power sources. Power supplies for these devices\u00a0(typically called \u201cDrivers\u201d)<\/em>\u00a0may be designed to operate at\u00a0either<\/u>\u00a0of these voltages, or often, at any voltage between\u00a0100-277V<\/strong>\u00a0(universal input supplies).<\/strong><\/p>\n Many commercial & industrial installations receive primary power at\u00a0347V (in Canada) or 480V (US), which often exceeds the rated input voltage for most lighting products. It is hazardous to operate a device beyond its rated voltage & is not acceptable by the local electrical authority. LED High Bay Light is the most popular light used in industrial applications. That’s why many electricians in North America are looking for a 347V or 480V input High Bay Light. Note:<\/strong>\u00a0Electrical supply in both Canada and the US typically operates at 60 Hz (frequency).<\/p>\n Note: \u00a0<\/strong>Nominal standard supply voltages in the USA<\/p>\n The U.S. has many similarities with Canada on lower voltage side (208\/120V 3-phase & 240\/120V split-phase supply) but differs on the higher voltage side as follows:<\/p>\n A supplementary device that reduces or \u201csteps\u201d the voltage down is required.\u00a0 This is when an installer would use a\u00a0step-down autotransformer<\/strong>.<\/p>\n Autotransformers<\/strong>\u00a0are a simple and reliable style of transformer consisting of a\u00a0single coil<\/u>\u00a0wound around a steel core that takes a higher voltage input (e.g. 347 or 480V) and \u201csteps it down\u201d to a lower voltage (e.g. 240V or 120V).<\/p>\n Tip:<\/strong>\u00a0These transformers must bear Safety Certification markings to show compliance with safety standards to the local electrical inspection authority.<\/p>\n Don’t want to use autotransformers? Then try our 347V or 480V input High Bay Light.<\/strong><\/p>\n Fireflier provides a much easier solution which allows you to use our high bay light directly with 347V or 480V input voltage without transformers. Adopted with our customized AC200-480V Sosen or Meanwell driver, our Ripple UFO LED High Bay Light<\/a> and Crown UFO LED High Bay Light<\/a> can work normally under AC277\/AC347\/AC480V input high voltage. The available power is 80W, 100W, 150W, 200W, 240W.<\/p>\nThe challenge<\/h3>\n
