EL/CCFL inverters are power supplies designed to power cold cathode lamps and light emitting diode (LED) lighting fixtures. These inverters convert alternating current (AC) input power into direct current (DC) that is used to operate the light source. EL/CCFL inverters use advanced switching technologies to ensure reliable operation and a long lifespan. They come with safety features such as short circuit protection, thermal overload and over-voltage protection. EL/CCFL inverters are used in a variety of display applications, such as LCD and plasma televisions, digital signage, backlighting for LCD and other displays, indoor and outdoor signage, and architectural lighting applications. Accessories such as dimmers and ballasts can be used with EL/CCFL inverters to assist in the operation of the lamps. Dimmers allow for control of the power output of the inverter, while ballasts regulate the current flow from the inverter and also help to reduce energy consumption, resulting in longer lamp life.
